Porcelain Tile Cleaning

Welcome to my Work History archive where you will find detailed examples of the cleaning and renovation of Porcelain tiles carried out in Northamptonshire

Cleaning and Polishing Porcelain tiles

Harder than ceramic tiles modern production methods have allowed a growth in the availability and design of Porcelain tiles which are known for their durability and water resistance making them a popular option for floors. Like Ceramic, Porcelain tiles are generally very easy to clean and need little maintenance however some are micro porous and do require sealing, you will need to ask you supplier which type you have installed as it can be very difficult to tell.

If your Porcelain tiles are of the micro porous variety then they will need to be sealed to avoid a build-up of dirt in the pores of the tile. For this we recommend Tile Doctor Ultra-Seal which works by impregnating the pores to ensure dirt can’t become ingrained there without changing the appearance of the tile itself.

Apart from sealing the biggest issues with this type of tile are usually grout related. Either the adjacent grout discolours over time or the tiler has been unable to remove excess grout from the surface of the tile, an issue known as Grout Haze or Grout Smears. Modern grouts can be particularly susceptible to the grout haze issue due to shorter working times and polymers in the grout which make it difficult to remove once dry. If this sounds familiar do contact us so we can advise you on how best to remove it.

Below you will find detailed examples of work we have carried out in the past, it should give you some idea of what’s involved and what can be achieved with the right techniques and products.

Grout Haze Removed From Porcelain Floor Tiles Northampton

Removing Polymer Grout Haze following Porcelain Floor Installation in Northampton

This client from Northampton called contact me about their newly installed Porcelain tiles which appeared to be much darker than they remembered from in the shop. They were disappointed with their appearance and so I agreed a time to pop round, diagnose the issues and come up with a solution.

Grout Haze Before Removal From Porcelain Floor Tiles Northampton

Once at the property I quickly established after testing a couple of tiles that there was grout haze over the entire area from installation. This happens when the grout starts to dry on the tile before it is cleaned and fully rinsed off. This problem was compounded by the customer vigorously mopping the floor with several different products trying to resolve this issue themselves and the product building up and attracting more soil to the areas, therefore darkening it further.

The test clean I conducted removed the grout haze to reveal the tile they had been originally expecting. Impressed with the results from the test they asked me to repeat the process on the whole floor which included the kitchen and adjoining dining area. I worked out a quote which was agreed and a date scheduled for my return.

Removing Grout Haze from a Porcelain Tiled Floor

Fortunately, the owner knew which grouting product was used when laying the floor, this was very useful as polymer-based grouts need a different approach to traditional grouts. As it turns out it was a polymer-based grout which makes sense as they are known to set faster and cause this problem as a result.

The process I used was to apply Tile Doctor Remove and Go to a workable section of the floor which was approximately 8m2. The solution was allowed to dwell for ten minutes or so prior to agitating with a rotary brush machine. This area was then rinsed off with water and a wet and dry pick-up machine. This process is used to break down the polymers in the grout but does not fully remove the haze from the tiles, that is covered in the next section.

Part two of treating the grout haze involves the application of Tile Doctor Grout Clean-Up to the tile and allowing it to dwell for a further ten minutes, a black buffing pad is then used with the rotary machine to scrub the product into the Porcelain tile. As before the soiled solution is removed with another rinse and extracted with the wet and dry pick-up machine.

Once that was done, I inspected the floor to ensure all the grout haze has been removed and repeated the 2nd stage process where required.

Sealing a Porcelain Tiled Floor

I allowed the floors to dry off overnight and returned the following day to apply Tile Doctor Ultra Seal Sealant over all the areas, this is especially good for protecting the grout lines from staining.

Given the dark colour of the Porcelain tiles it’s difficult to appreciate the improvement from the photographs, my customer was extremely happy with the result though and left the following glowing review:

“Fabulous service from Phil and great results really really pleased. Lovely man and very hard working. Thank you”

Before leaving I made sure to discuss aftercare cleaning, which for this floor I recommend using Tile Doctor pH Neutral Tile Cleaner which is a gentle but effective cleaning product designed for use on sealed tile and stone.

Dirty Grout in Titchmarsh Kitchen After Cleaning

Cleaning up newly installed Grout in Titchmarsh

This customer from Titchmarsh near Kettering was unhappy that the Porcelain floor tiles that were installed in her kitchen six months prior were proving difficult to clean and that the grout line had turned from a grey to black and whatever she tried she just could not keep this floor clean. On inspection I soon discovered that no or very little sealer had been applied to the Porcelain which is not unusual as most Porcelain does not require a sealer however Micro Porous Porcelain does and she should have been advised by the shop that sold her the tiles that this was the case. A quote was given which she was happy with and I returned the following week to sort the problem out.

Deep Cleaning Porcelain Tile and Grout

To protect the kitchen units I covered them in a plastic and then moved onto to deep cleaning the tiles with a dilution of Tile doctor Pro Clean which was applied and left to soak in for a while before hand scrubbing the floor on my hands and knees with stiff brushes. This did made an improvement but something stronger was required to get the grout looking better so it was back down to the floor with hand brushes again but this time I used Tile Doctor Grout Clean-Up which is an acid that can remove grout smears and mineral deposits, in the end I actually used two litres of Grout Clean-Up to restore the grout to about 95% of its correct appearance and once done I gave the floor a thorough wash down to remove any trace of product.

Dirty Grout in Titchmarsh Kitchen During Cleaning

Sealing Porcelain Tile and Grout

This grout should have been correctly sealed from day one and luckily for the client it came up to her satisfaction otherwise the only other option would have been to use a Grout Colourant which would have been more costly but cheaper than replacing the grout altogether. Had the grout been much older this may have been the best option as I suspect the result from cleaning would have been less effective. The last step was to seal the tiles and grout using Tile Doctor Ultra Seal which is a natural look sealer that provides maximum stain protection and is recommended for use in kitchens. Before leaving I gave the client written instructions on maintenance which she found very helpful.
