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 Buckinghamshire

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.


Limescale Stained Slate Shower Floor Renovated Penn

Removing Limescale from Slate Wet Room Tiles in Penn

This is a great example of what we can achieve with very stained Slate Tiles so well worth sharing. The customer was from Penn in Buckinghamshire and as you can see from the photo below the Slate tiled floor in their wet room was heavily stained with thick limescale mainly around the shower trap where the water collects.

Limescale Stained Slate Shower Floor Before Cleaning Penn

Buckinghamshire is known for its hard water problems which basically means the water contains high levels of calcium carbonate. These deposits are carried in the water and left on the tiles after each shower resulting in Limescale. You can reduce the problem by installing a water softener and it can be dissolved using some of the strong products you find in supermarkets however these are acidic and can etch natural stone if you are not careful. Always read the label!

In this case my customer had just moved into the house and wanted to improve the look of the bathroom and then eventually they planned to change the whole bathroom itself, but in the meantime wanted it cleaned and restored.

Cleaning a Slate Tiled Shower Floor

To renovate the Slate tiles, I started with the application of a strong dilution of an alkaline product made by Tile Doctor called Pro-Clean. This is a great grout cleaner and when used as a strong dilution it will also strip off any sealer remaining on the Slate.

I used the usual method of spraying the Pro-Clean onto the tile and grout and leaving it to soak in for at least ten minutes so it can get to work. It was then scrubbed in with hand tools and an 80-grit silicon carbide brush which is a very effective combination. This gave the stone a deep clean and removed some of the thick limescale on the tiles which was rinsed off with water.

Once the floor had been cleaned and stripped back, I used another Tile Doctor product called Grout Clean-up which is an acidic cleaner and is applied in the same way. Because the build-up of Limescale was so thing I found that a lot of pressure was needed when scrubbing the tiles and, in some areas, I needed to use a scrapper to take off the top layer.

Sealing a Slate Tiled Shower Floor

After cleaning off all the limescale and giving the stone a good rinse, I dried the floor using a white rag and left it to dry off so it would dry enough for sealing. After giving the floor time to dry I used tile doctors oil-based sealer called X-Tra seal putting down a thick coat and allowing the tiles to soak up the sealer. After some time, the floor was then buffed with a cloth to remove the excess and then a second coat was applied.

X-Tra Seal adds the oil back into the stone which restores the dark tones and bring out the natural colour in the Slate, its also rated for external use so will cope well with the damp conditions of the wet room. After that coat had dried a 6-inch 1500-grit buffing pad was used to remove excess sealer and add a slight sheen to the floor.

The fresh sealer should make the Slate less prone to limescale deposits however its not going to prevent the problem indefinitely. Also, for the aftercare of sealed shower tiles, I recommend Aqua-Pro which is a mild cleaning product designed for regular use and won’t harm the sealer like many of the stronger products you find in supermarkets.

Porcelain Tile and Grout Renovation Chalfont St Peter

End of Tenancy Renovation of Porcelain Tile and Grout in Chalfont St Peter

I recently paid a visit to a rental property in Chalfont St Peter which had Porcelain tiled floor which needed an End of Tenancy Clean. Porcelain tiling is a great choice for a rental property as its very to maintain however in this case it was the grout that was letting the floor down.

Porcelain Tiled Floor Before Cleaning Chalfont St Peter

It seems the previous tenant had tried using a white grout pen to colour the grout lines when they first moved in and since then the colourant has started flaking off resulting in a very patchy appearance and the exposed grout becoming darker.

The client wanted me to come in and clean the floor and to make the grout lines unison. The property wasn’t going to be rented out again as the owner was planning to move back in after living abroad for several years.

Deep Cleaning Porcelain Tile and Grout

On the first day I started giving the Porcelain tile and grout a much needed deep clean using a Rocky floor machine fitted with a Silicon Carbide brush and lubricated with a strong dilution of Tile Doctor Pro-Clean. Carbide brushes are perfect for hard floor cleaning and in this case had the additional advantage of cleaning away the flaky grout pen.

This cleaning process was applied section by section vacuuming up the slurry with a wet vacuum along the way. I then hand scrubbed the grout lines with Grout Colourant Pre-Treat Cleaner which is an effective ready-to-use cleaner designed to lightly etch the surface of the grout to ensure a better adhesion with the colourant. It also removes dirt, soil, soap scum and hard water deposits from grout joints. Once everywhere had been treated I mopped the floor with Neutral Tile Cleaner, rinsed with water, extracted with the wet vacuum again before finally leaving the floor to dry off overnight.

Applying White Grout Colourant to a Porcelain Tiled Floor

On day two I knew my main problem would be making sure that the White grout colourant was able to adhere to those areas of grout that had been coloured with the pen. I didn’t have to worry though as it worked perfectly. The application basically involves using a small brush to push the colourant into the grout lines and gently cleaning up the edge of the tiles to remove the excess colourant before it can dry.

After the first coat dried it brighten the floor massively however in some of areas you could still make out the old from the new so I needed to give the grout lines a second coat using the same technique as before. Once the second coat had been applied, I allowed it to settle and go off before giving the floor a check over to make sure I was happy with the result.

My customer was over the moon with the difference and was much relieved that the floor had been restored after the condition the previous tenants had left it in.

Ceramic Tiled Floor Before and After Renovation Uxbridge

Removal of Linseed Oil from a Ceramic Tiled Floor in Uxbridge

This is a small Ceramic tiled floor that a client had laid in his workshop next to his house in Uxbridge. As you can see from the photo the floor was in an indescribable mess and I was asked to pop round and quote for sorting it out. Uxbridge is actually classed as Middlesex but being close to the M25 and M40 I find it easy to reach.

Ceramic Tiled Workshop Floor Before Cleaning Uxbridge

As requested, I called in to survey the floor which was not a pretty site. In turns out that the tiler had applied boiled linseed oil to the floor (which the tiles did not need), and this had formed a horrible sticky residue on the surface. The client had conducted several unsuccessful attempts at cleaning up the floor and was unsure it could be rectified. Once of the attempts involved using acid which failed to remove the oil and unfortunately did do some damage to the grout causing it to discolour.

Undeterred, I was confident we could sort the problems out and restore the appearance of the tile and grout. I discussed with the client what we could do to clean the floor and we agreed a price to carry out the work out.

Cleaning a Ceramic Tiled Workshop Floor


Returning the following week, I first tackled the floor using Tile Doctor Pro-Clean applied neat, left to soak for ten minutes and then scrubbed in with a rotary floor buffer fitted with a black scrubbing pad. Pro-Clean is a highly concentrated multi-purpose tile cleaner, which when left to dwell, breaks down all types of dirt from oils through to grease and grime. It’s particularly good for very heavily soiled areas and it did a good job at removing the Linseed Oil. I rinsed the soiled solution with water and extracted the now soiled cleaning solution off the floor with wet vacuum. Wet vacuums are a great resource for Tile Doctor work, they make light work of removing liquids and this keeps the mess to a minimum.

I followed up the cleaning with a light buff of the tiles using Tile Doctor Grout Clean-up to remove the grout smears also left behind by the tiler. Cleaning the excess grout off the tiles made a huge difference to the floor, which you can see in the completed picture.

Ceramic tiles have a glazed surface that won’t accept a sealer or Linseed Oil for that matter. There is therefore no need to apply any sealer or coating to this type of tile. They are generally very hardwearing and a suitable choice for a workshop like this. Hopefully, now the sticky oil has been removed the client will find the floor much more durable and easier to maintain.

The treatment worked well and I was able to complete the project in one day. The floor now looks like it should have done following the initial installation. Although it is only a small area, the difference is quite dramatic. My client was certainly pleased with the transformation and left the following feedback.

“Andrew is an expert in his field, and after an inexperienced tiler incorrectly used boiled linseed oil, Andrew worked to restore the tiles to their original beauty. I felt confident in him, he was a pleasure to work with, and his extremely professional. Very happy & highly recommended”

Limestone Tiled Kitchen Floor Before and After Cleaning Knotty Green

Limestone Kitchen Floor Tiles Transformed in Knotty Green

Below are photographs of a Limestone tiled kitchen floor at a house in Knotty Green near Beaconsfield. The stone floor had lost its polish with use and now appeared flat and unattractive additionally the grout had darkened severely with dirt and was overdue a good scrub to get it clean.

Natural stone is actually a porous material that needs to be sealed in order to prevent dirt from becoming ingrained however unless its maintained constant foot traffic on floor tiles wears down the sealer leaving the stone vulnerable and difficult to clean effectively.

Burnishing and Cleaning a Limestone Tiled Kitchen Floor

If you have read other posts on my website, you will know that we find the best way to restore the appearance of polished stone is through the application of a set of diamond encrusted burnishing pads of varying grits to grind away dirt and slowly build the polish on the stone.

You start with the application of the coarse 400-grit pad which is fitted to a rotary buffer machine and applied to the floor with water to lubricate the process, the resultant slurry is then rinsed off with water and extracted with a wet vacuum. Next is the Medium 800-grit pad and then the Fine 1500-grit pad, both applied in exactly the same way.

Once I had completed the whole floor with three of the four pads I got to work cleaning the grout. For this, I used a strong dilution of Tile Doctor Pro Clean, our reliable alkaline cleaner, in combination with a handheld scrubbing brush. Once the grout was clean I gave the floor another rinse with water and then removed as much liquids and moisture as possible using the wet vacuum leaving it to dry off fully overnight.

Sealing a Limestone Tiled Kitchen Floor

The following day I returned to complete the floor starting with the application of the fourth diamond encrusted pad in the set of four which is a Very fine 3000-grit using a method we call a spray burnish which essentially involves applying the pad dry to the floor with a small amount of water sprayed on the stone. This process closes the pores in the floor and adds a good quality sheen to the tile.

Finally, I applied two coats of Tile Doctor Ultra Seal which is an impregnating sealer that penetrates into the pores of the stone to provide maximum stain protection from within. This sealer is also completely transparent, so it does not affect the natural look of the stone.

Ceramic Tile Wendover After

Deep Cleaning Textured Ceramic kitchen floor tiles Wendover Bucks

We were asked to clean these textured ceramic floor tiles in Wendover Bucks which had become heavily soiled and ingrained with dirt leaving the tiles with a black appearance, the grout lines had also become stained and discoloured. Our customer had tried all types of cleaning agents but could never get the desired effect.

Cleaning a Textured Ceramic Tiled Floor

A dilution of Tile Doctor Pro-Clean alkaline tile cleaner was applied throughout the tiled floor and worked in with the aid of a scrubbing pad fitted to a rotary machine, a stiff hand brush was also used along the grout lines and this managed to lift most of the soiling from the floor.

Next step was to use our powerful truck mounted heated turbo system which jet washed the remaining particles out of the crevasses of the stone. This system uses high pressure heated water though a spinner tool, it’s an amazing tool that returns the dirty water directly back to a recovery tank leaving the floor chemical free and neutralised.

Before leaving I recommended to the customer that regular use of Tile Doctor Neutral Tile cleaner would help to keep their tile and grout in better condition.

Ceramic Tile and Grout Before and After

Grout colour seal and Ceramic tile clean in Chalfont St Giles

We were asked to improve the appearance of this Ceramic tiled floor and Grout installed in a kitchen in Chalfont St Giles which over a few years had become difficult to keep clean and the grout lines had become stained and discoloured.

Ceramic Tile and Grout Before Ceramic Tile and Grout Before

Cleaning Tile and Grout

Our first task on day one was to clean the Ceramic tiles and Grout so we created a diluted 50/50 mixture of tile doctor Pro-Clean and Nanotech UltraClean, the two products combine to provide a very powerful tile friendly alkaline cleaner with tiny sized abrasive particles. This was left to soak into the tile and grout before being agitated and scrubbed with a scrubbing machine running on low speed. We also used stiff grout hand brushes along the grout lines. Once we were happy with the overall condition of the tile and grout it was washed down using clean water and the resultant soiled solution extracted from the floor using a wet vacuum. I’m pleased to say that using this method we were able to return the tile and grout back to its original colour.

Whilst this was a fantastic transformation the grout lines being porous would untreated soon become dirty and discoloured. The only answer to this problem is a permanent colour seal to the grout lines which not only aids the future floor cleaning, but improves the whole appearance of the floor.

Applying the Grout Colour

Before applying a Grout Colour it’s important to ensure the grout is clean of grease and dirt naturally we had just cleaned this floor so this was not a problem I only mention it in case you were considering taking on a similar task yourself.

Once the grout has dried you can start applying the colourant which is a relatively straightforward process of squeezing the product onto a toothbrush and running it onto the grout. Don’t be tempted to use an old toothbrush for this purpose as it may contaminate the colourant leading to discolouration in the finish.

We completed the project the next day using an Aqua Mix sand coloured Grout Colourant; the customer was extremely pleased and commented how whole clean and efficient the process was.
