Grout Cleaning

Welcome to my Work History archive where you will find detailed examples of the cleaning and renovation of Grout carried out in South London

Cleaning and Renovating Grout

The top layer of grout is porous and can absorb grease, dirt and limescale. Spillages such as wine, lemonades or greasy substances will cause marks and patches in the joints in the floor. Grout between wall-tiles particularly in damp areas like bathrooms will become dirty and unattractive as a result of Mould, Mildew and Limescale.

Mould is one of the most unsightly problems, which usually starts off in the wettest area of the room, this could be the bottom of the shower or bath, then starts to spread and if left unchecked could cover a large area of the wall.

Another common issue we find is a problem known as Grout Haze or Grout Smearing where a thin layer of grout has been left to set on the surface of the tile. Once grout has set it is difficult to remove.

Discolouration of grout joints in bath or shower areas due to continued use of acid formulated shampoos and soaps. This causes yellow orange and pink stains to the grout over even a short period of time. Whilst Grout Joints can be cleaned, badly stained grout may need to be re-coloured.

Protecting your grout in advance with a sealer will prevent most of these issues and although relatively unknown in the UK, protection awareness is growing. Sealing forms an invisible barrier between the grout and the surface, this will then protect your investment for years to come.

We have solutions for all the problems listed above and below you will find detailed examples of work we have carried out in the past to resolve many of these issues. It should give you some idea of what’s involved and what can be achieved with the right techniques and products.


Bathroom Floor Grout Restoration in Tooting SW17

Bathroom Floor Tile Grout Restoration in Tooting SW17

A client was renovating a house in Tooting and wanted to see what could be done to improve the Ceramic floor tiles in the bathroom without the expense of a major overhaul. Having discussed the floor over the phone I was confident it could be improved and agreed a date to come over and survey the tiles and provided a quote for their renovation.

Bathroom Floor Grout Before Restoration in Tooting SW17

Except for one cracked tile, the tiles were in good condition and I could see it was really the grout that was bringing the bathroom down. The grout was generally discoloured and some had cracked and become loose. This cracking issue is indicative of using an inflexible grout when tiling on a wooden floor as these floors tend to have a bit of movement in them.

I discussed my renovation plan with the customer and provided a quote for carrying out the work which was accepted.

Renovating Bathroom Floor Grout

On the first day I set about raking out the cracked grout and stripping out the silicone between the tile and the bath. Silicone seems to attract mould and although it can be cleaned to some extent, I usually find its more effective to simply replace it. I then tidied up the bathroom to remove the waste grout and silicone, so the area was ready for grouting. I used a flexible White grout for this in order to match the original, although most of that was no longer White due to the staining.

I left the grout to set overnight and returned the next day to complete the job starting with the re-application of the silicone sealant, again in White but this time using an anti-mould variety. My attention then turned to the floor tile grouting which of course was now a mixture of fresh new grout and stained grout. I had realised this would be the result, so I had come prepared and was ready to apply Tile Doctor Grout Colourant in white to make everything uniform.

Before applying the colourant, I prepped the grout joint with Tile Doctor Pre-treat cleaner that is an acidic cleaning solution that is sprayed onto the grout and then scrubbed in. This cleans the grout joints, and the acidic nature of the cleaner helps prepare the grout to achieve a better bond with the colourant. The grout was then wiped with a wet sponge to remove the dirt and then dried ready for the colourant. Although the cleaner had helped to clean the grout and remove surface dirt it can’t do anything about deep seated staining, so colouring was still necessary.

Once the grout was dry the White grout colourant was painted onto the grout using a small brush wiping off any excess from the tile as I went. The Tile Doctor range of Grout Colourants come in eleven different colours and form an epoxy barrier over the grout preventing dirt from reaching the grout line and making it much easier to keep clean.

Once the colourant had dried, I gave the floor a quick clean with Tile Doctor Neutral Tile Cleaner to get the ceramic tiles clean and the job was complete. The refreshed grout now has a consistent white appearance, and it really lifted the appearance of the bathroom.

Porcelain Tile Bathroom Grout Cleaning Wandsworth

Porcelain Tiled Bathroom Grout Renovation in Wandsworth

This is a great example of how easy it is to improve the appearance of a tiled bathroom. In this case the property was in Wandsworth and the tiles were Porcelain. My client had originally asked if I could re-grout their bathroom tiles which included the shower, wall and floor tiles in a room that was around 5sqm.

Porcelain Bathroom Tile Before Grout Renovation Wandsworth

We discussed the bathroom, and I pointed out that if we re-grout the tiles it would only get grubby again at some point. The problem is that the grout is cementitious which leaves it rough and attracts dirt easily. I recommended cleaning up the grout and then applying a grout colourant which would seal the grout in making it much easier to clean. I also offered to remove the silicone sealant between the edges of the bath and tiles. Unfortunately, once mould gets into the silicone, you’re fighting a losing battle, and it is best to just replace it.

Re grouting a Porcelain Tiled Bathroom Floor

Before colouring the grout, it needs to be prepared with an acidic cleaner that will not only remove any dirt but also etch the surface of the grout to improve the bond. Tile Doctor Pre-Treat Cleaner is the product we use for this purpose, but I decided in this case to go with a different product as the floor tiles had some old silicone on them which had been left to dry out. To resolve this, I used a different product in the range called Tile Doctor Grout Clean-Up which is primarily designed for removing grout haze.

Porcelain Bathroom Tile During Grout Renovation Wandsworth

It was only a small area, so I worked the Tile Doctor Grout Clean-Up into the tiles and grout by hand and then rinsed it off with water and extracted with a wet vacuum. The grout was then dried, and I started applying the Tile Doctor Grout Colourant in white with a small brush wiping off the excess as I went. The colourant is available in a range of eleven colours so there is usually a match for most situations. The colourant adds an epoxy barrier over the grout; this then prevents dirt from going into the grout line and means the floor is much easier to keep clean.

The last step in the renovation involved carefully stripping out the old silicone and replacing it with a new anti-mould variety. This last step really finished off the bathroom giving the impression it was a new installation.

My clients were very happy with the result, the bathroom was transformed, and they were relieved that the problem was solved so easily.

For aftercare cleaning I recommended regular use of Tile Doctor Neutral Tile Cleaner which is a mild yet effective tile and grout cleaning product that would help keep the bathroom looking good going forward.

Shower Tile and Grout Cleaned and Renovated in Battersea Shower Cubicle

Ceramic Tiled Shower Cubicle Refreshed in Battersea

I was contacted by a customer in Battersea who was concerned about the state of their Ceramic Tiled shower cubicle. Ceramic tiles are glazed so usually very easy to keep clean however grout has a rough surface and attracts dirt easily. Where this happens it best to keep on top of the problem with regular cleaning as once you get a deep-seated stain on grout it’s very difficult to get it clean again.

The photograph below shows the worst of the problem where dirt had collected behind a wire basket that was fixed to the wall. The basket allowed dirt to build-up behind it and had deposited rust on the tile and grout.

Ceramic Shower Before Tile Cleaning Battersea

Maintaining grout is a large part of the work Tile Doctor does and we have several tried and tested products and processes for doing this. Having spoken to the client over the phone and having been sent photographs via email I created a quote for the work which should only take a few hours. My customer was happy with the quote and we agreed a date to do the work.

Cleaning a Ceramic Tiled Shower Cubicle

To begin, I cleaned the grout lines using our acidic cleaning product, Tile Doctor Grout Clean-Up. The product is decanted into a spray bottle and sprayed onto the tile and grout where it was left to dwell for ten minutes before being scrubbed in with a handheld scrubbing brush. Spraying the solution onto the wall mixes it with air to make it lighter and more able to stick to the wall.

Being a concentrated phosphoric acid cleaner, Grout Clean-Up effectively removes mineral deposits including rust and old grout smears from the tile surface to leaving it looking much fresher, it also prepares the grout for a superior bond with the grout colourant that was to be added later.

Following this, I rinsed down the tile and grout with water to remove the dislodged dirt. The next step was to remove all the existing silicone mastic with a sharp knife; the mastic sealant stained with mould and much in need of replacement. Once all the rubbish was swept out, I dried any remaining dampness from the grout and tiles with a heat gun.

I then moved onto to recolouring the grout using a Tile Doctor Grout Colourant which is simply painted onto the grout lines using a small brush and any excess wiped of the tile before it dries. There are eleven colours available in the Tile Doctor colourant range and in this case, we chose a colour to match the tiles.

Ceramic Shower After Tile Cleaning Battersea

The application of Grout Colourant not only colours the grout joints – it also seals the grout in so dirt can’t become stuck in its rough surface, this also makes it very easy to clean going forward.

Once the restoration was finished, I resealed the shower base with fresh mould resistant silicone mastic to match the tile and grout. Tile Doctor don’t sell this but there are many makes available from local DIY stores.

Black Slate Kitchen Floor Renovation Tooting

Black Slate Tiled Kitchen Floor Renovated in Tooting

The photos below are of a Black Slate Kitchen floor at a property in Tooting SW17, which as you can see had lost all its colour and character. I went over to survey the floor and discussed a renovation plan with the owner.

One of the problems was the grout which like the tile hadn’t faired very well over the years and being in the Kitchen was subject to staining. I explained that like all stone floors the Slate needed to be sealed in order to keep the dirt out of its pores and keep it looking its best. Sealers however wear down with use and in this case the floor hadn’t been deep cleaned and sealed for some time.

I costed out a renovation plan which included deep cleaning the Slate tile removing any remaining sealer in the process, renovating the grout, and then re-sealing the whole floor to bring back the appearance of the stone and protect it going forward. Happy with the quote we agreed a date to start the work.

Deep Cleaning a Natural Black Slate Tiled Kitchen Floor

Normally I would use a Tile Doctor product called Remove and Go to remove the sealer, however in this case testing had shown that what was left of the sealer could be removed with Pro-Clean which is also our go to Tile and Grout Cleaner.

I used a strong dilution of Pro-Clean to do this, spraying it onto the floor and leaving it to soak in for ten minutes and break down the dirt etc. Then using a black scrubbing pad fitted to a heavy rotary buffer machine it was worked into the Slate to release the dirt and old sealer. The floor was then rinsed with water and the soiling extracted with a wet vacuum.

The pads can struggle to get into the corners and edges of the floor and the recesses of the grout line. So, to complete the cleaning a handheld scrubbing brush was used and a wire brush run along the grout lines, again with more Tile Doctor Pro-Clean. After another rinse and extraction with the wet vacuum the floor was left to dry aided with a couple of floor blowers.

Grout Colouring and Sealing Black Slate Tiled Kitchen Floor

Once dry the grout was coloured with a Black Tile Doctor grout colourant which is basically painted onto the grout with a small brush and any excess wiped off the tile. This grout colourant gives the grout a uniform appearance and adds an impenetrable barrier over the grout sealing it in and keeping it safe from further staining. Keeping grout clean in a kitchen is always a problem so the colourant will protect it and make it very easy to clean.

Black Slate During Cleaning Grout Colouring Tooting

The last step was to seal the Slate for which I used Tile Doctor X-Tra Seal. This was chosen because it’s an impregnating oil-based sealer that will restore the beautiful dark colour in the stone. Impregnators work by occupying the tiny pores in the stone thereby forcing dirt to remain on the surface where they can easily be cleaned away.

Black Slate During Sealing Tooting

In the subject of maintenance cleaning, I recommend the use of Tile Doctor Neutral Tile Cleaner which is a gentle but effective cleaner that won’t harm the sealer. Many of the floor cleaning products you find in supermarkets etc are not for use on sealed stone, they contain strong chemicals such as bleach etc which will strip off the sealer prematurely so best avoided.

Bathroom Floor Grout Cleaning Colouring Gipsy Hill

Bathroom Floor Tile Grout Renovated in Gipsy Hill SE19

The Grout on this tiled floor in the bathroom of a property near Gipsy Hill SE19 was as you can see from the photo below in a bit of state. Originally White the colour of the grout had darkened to black in numerous areas and was bringing down the appearance of what was a lovely bathroom.

The floor tiles were Travertine effect Ceramic or Porcelain and as you would expect with tiles of this nature in very good condition. Ceramic and Porcelain tiles are not porous and so very easy to maintain, however what tends to happen is the dirt is washed off the tiles straight into the adjacent grout line where due to the rough nature of the grout it gets stuck.

Bathroom Floor Grout Before Cleaning Gipsy Hill

My renovation plan for tackling dirty grout is to start with a strong grout cleaner like Tile Doctor Pro-Clean and if the staining is still evident apply a Grout Colourant. I discussed this plan with owner of the property who were happy that one way or another the problem was about to be resolved.

Cleaning a Natural Black Ceramic Tiled Bathroom Floor

The first step in renovating this floor was to tackle the grout which was clearly the biggest issue with this floor. This work started by applying a strong dilution of Tile Doctor Pro-Clean along the grout lines and then waiting for about ten minutes before scrubbing it in with a wire brush. I also used a 6-inch Black scrubbing pad fitted to a hand-held polisher to clean the tiles which as mentioned earlier only needed a light clean. The floor was then rinsed with water and then dried with a wet vacuum to remove the excess water and slurry from the cleaning.

The grout responded well to the treatment but unfortunately the staining was simply too deeply seated to make it look new again so I decided to adopt plan B and apply a White Grout Colourant. These colourants have the added advantage of sealing in the grout and are very easy to clean.

The grout was force dried and then once I was happy it was dry enough, I started the process of applying the grout colourant to the grout lines. Grout Colouring is a straightforward and involves using a small brush to paint the colourant onto the grout and then wiping the excess off the tile as you go. We find a wet wipe works well for this. Two coats of Grout Colourant were applied.

Whilst that was drying, I stripped out the silicone sealant around the edges of the bathroom and replaced with new. This last step really finished off the transformation and it would have been obvious if I had missed it.

Once finished the floor looked like a new installation and the Grout Colourant should keep it looking that way for many years to come.

Natural Black Slate Bathroom Floor Tile Renovation Brixton

Black Slate Tiled Bathroom Floor Transformed in Brixton

This bathroom floor at a property in Brixton was laid with natural Black Slate tiles around five years ago and then badly restored/cleaned three years ago. Some of the more noticeable problems included a build-up of limescale on top of old patchy grout paint and the sealant on the slate was failing allowing the tiles to absorb dirt. The result was a a very unappealing and grubby looking floor.

Natural Black Slate Bathroom Floor Tiles Before Cleaning Brixton

Unhappy with what could be a stunning Black Slate floor the owner contacted Tile Doctor and I was asked to visit the property, survey the tiles, and provide a quote for its renovation.

Cleaning a Natural Black Slate Tiled Bathroom Floor

To get the grout clean of dirt it was scrubbed with a stiff brush and a strong dilution of Tile Doctor Pro-Clean. The grout was then spot treated with Tile Doctor Grout Clean-Up to help remove the old grout paint and a ready mixed grout used to fill gaps where the grout had become dislodged.

Next, I addressed the slate tiles and applied Tile Doctor Remove and Go to remove what was left of the old sealer, the solution was left on the tiles for ten minutes and then agitated with a brush to dislodge the old sealer and dirt. The floor was then rinsed with water and the soil extracted with a wet vacuum.

Once done I could see more work was needed so a 200 grit 6-inch pad was fitted to a hand-held buffer and run over the tiles to further clean up the tiles along with a carbide brush to help reduce the lippage between the tiles. Once done the floor was rinsed and extracted again with water multiple times to ensure no trace of products was left on the Slate.

Sealing a Natural Black Slate Tiled Bathroom Floor

The floor was left for a few hours so it could dry and when dry sealed with two coats of Tile Doctor Colour Grow applied with a paint pad and cloth to add protection and to make the dark shades in the stone stand out.

To complete the look a Tile Doctor Black Grout Colourant was then applied to the grout lines so it would match the dark Slate better. The colourant has the added advantage of sealing in the grout and making it much easier to keep clean.

My client was very pleased with the transformation and left the following feedback for me which is always appreciated:

“Really excellent job from Daniel & team. My natural slate bathroom floor looks better than when it was first laid. Superb communication and finished job. I can’t recommend them enough. 5*”

The client has since asked us to come back to complete more works on the Limestone bathroom walls which of course we are happy to oblige!

For aftercare I recommended the use of Tile Doctor Neutral Tile Cleaner for the regular cleaning of tiles. This pH neutral product will keep the limescale at bay and eliminates the build-up of soap, it is mild enough to use every day and has a nice fresh smell.

Removing Limescale from Porcelain Swimming Pool tiles in Oxshott

Removing Limescale from Porcelain Swimming Pool tiles in Oxshott

The owner of this swimming pool at a large residence in the suburban village of Oxshott had put the property on the market and naturally wanted the pool area to look its best. The pool was surrounded by Porcelain tiles which are very resilient and generally a good choice for a swimming pool surround, additionally the slate effect tiles in this post had a riven surface which would make them less slippery than the highly polished variety. The chemicals used in swimming pools however are quite strong and I suspect this has contributed to the build-up of Limescale on the surface of the tiles.

Cleaning Porcelain Tiles

The first job was to give the tiles a deep clean and this was done by scrubbing in Tile Doctor Pro-Clean diluted 1 part cleaner to four parts hot water using a black scrubbing pad fitted to a rotary machine. Once scrubbed the soiled cleaning solution was removed using a wet vacuum and the tiles given a thorough rinse. There were a lot of tiles to clean and naturally care has to be taken to avoid getting any cleaning solution in the pool.

Porcelain Pool Surround Oxshott Before Cleaning Porcelain Pool Surround Oxshott Before Cleaning

After rinsing the tiles were dried with the assistance of an air mover so we could get an idea of what other remedial work would be required and in this case it became clear where the areas with Limescale staining were.

Removing Limescale from Porcelain Tiles

To remove the Limescale each stain was spot treated using Tile Doctor Grout Clean-up which is a strong acid based cleaning product normally used to remove grout smears from tiles but also equally useful at dealing with mineral deposits such as Limescale. You have to be very careful with acids on tiles, especially natural stone so once it had done its job the tiles were thoroughly rinsed and the whole floor rinsed again once we have completed everything.

Marble Tiled Hallway Farnborough

Marble Tiled Hallway Cleaned and Polished in Farnborough

It’s not our local area but following a recommendation to this client by another customer we were asked to have clean and seal these Marble tiles in the hallway of a house in Farnborough.

Marble Tile Cleaning and Polishing

There was no sealer present on the Marble tiled floor so gave the floor a clean with a dilution of Tile Doctor Pro-Clean which is safe to use on stone floors, Pro-Clean is also very effective on grout so we took the opportunity to get into the grout lines as well. Once we were happy with the tile and grout we removed the soiled cleaning solution using a wet vacuum and washed the floor down with clean water.

The next step was to use a set of diamond encrusted burnishing Pads fitted to a rotary buffing machine to polish the floor. The pads come in a set and are very effective at restoring the shine back on Marble, Limestone and Travertine etc.

Once the floor was polished we applied two coats of Tile Doctor Ultra-Seal which provides a high level of surface protection whilst maintaining the natural look of the Marble tiles. Once the sealer had dried we buffed the floor again using a white polishing pad.

A solution of Tile Doctor Pro-Clean was applied to the floor and left to soak for a short while before being scrubbed in with a rotary machine fitted with a black scrubbing pad. The grout also need attention, unfortunately we don’t have a machine that will get into the grout lines so this had to be manually scrubbed by hand using a grout brush, which as you can imagine took some time to do. The soiled cleaning solution was then removed using a wet vacuum and the floor thoroughly rinsed with water and then left to dry overnight.

Once we were happy with the floor it and it had managed to dry off we sealed the floor using six coats of Tile Doctor Seal and Go which provides surface stain protection to the quarry tile and grout and also leaves a nice deep low sheen on the tile surface. The lady was over the moon with the results and her husband was even happier because it meant he didn’t have to pay out for a new kitchen.

Central London Office Slate After

Slate Floor Cleaning at a Central London Office

I was asked by a building company to look at some slate flooring that was laid during a refurbishment to the offices of a German television station based in central London.
The architect was not happy because there appeared to be some grout haze and some grout along the ridges that you get in slate. I carried out a demonstration to the building manager and she was pleased with the result and we were awarded the job.

Because of the nature of the business I had to do the job out of hours, which suited me because there were 4 toilet areas to do over 6 floors and I was able to get on with the job without any interruption.

Central London Office Slate Before Central London Office Slate Before

Slate Tile Cleaning

On my arrival I laid a coating of Tile Doctor Remove and Go mixed 50/50 with NanoTech Ultra-Clean to 2 toilets and left it to dwell while I brought all my equipment in and set up. These two products together create a very powerful stripper cleaning solution ideal for the job in hand. I left the products to soak into the tiled slate floor of the first toilet for an hour before scrubbing it in using water and a hand scrubbing brush. The soiled solution was then removed using a wet vacuum and then rinsed and sprayed with Tile Doctor Grout Clean-Up to remove any remaining grout haze off the surface of the tile. The slate was the given two mores rinses with clean water before being left to dry.

Before starting on the next floor I left a mixture of Remove and Go and NanoTech Ultra-Clean to dwell on the next floor. I then carried on with this process described above until all the floors were cleaned.

Slate Tile Sealing

Once the floors were dry I put a single coat of Tile Doctor Colour Grow sealer down on each floor which is a sealer which really brings out the natural colour of the stone.
The client had requested a shiny final finish so the sealing was completed using two coats of Tile Doctor Seal and Go on each floor.
