We were asked to take a look at these Marble effect Porcelain floor tiles installed in the Kitchen of a house in Maidenhead. Porcelain are a very robust tile which unlike natural stone does not normally need a sealer; they can still become surface stained however especially in a kitchen but the grout is more likely to become stained than the tile which was certainly the case with this floor.
Cleaning black Porcelain floor tiles
To get the Tile and Grout clean we applied a mild dilution of Tile Doctor Pro-Clean which was left to dwell and soak into the tile and grout for twenty to thirty minutes to help break down the oils, grease, skin fats, food fats and other soils which are found in the kitchen and stain the floor. The solution was then worked into the tile using a heavy rotary machine fitted with a white pad and also manually into the grout using a stiff grout scrubbing brush.
The next step was to remove the soiled cleaning solution and give the floor a good rinse and for this we have invested in a high pressure, hot water, vacuum system that has been installed in our van. This tile and grout cleaning machine simultaneously extracts dirty solutions from the floor whilst blasting engrained soiling away from the grout and tiles.
After deep cleaning and extraction the floor was allowed to dry for a period of 1 hour and an air mover was introduce to help encourage drying.
The Porcelain tiles were now looking fantastic and the grout improved however the trouble with grout is that it is porous, and so gets dirty quickly and is difficult to clean. So to get the Grout back to the colour it once was we applied a Grout Colourant to the grout lines which not only restored the uniform appearance of the grout but also adds an impervious layer to the grout protecting it from staining and making it easy to clean going forward.
Like a sealer the grout colourant can be damaged through the use of aggressive cleaning products and heavy scrubbing so for aftercare I recommended the use of a mild cleaning solution such as Tile Doctor Neutral Tile Cleaner applied with a microfiber cloth to simply wipe the grout lines clean again.
These Porcelain floor tiles had been laid in the hallway of a block of flats in Luton and had seen a fair amount of foot traffic resulting in the usual build-up of dirt and grime making it well overdue for a deep clean.
Cleaning Ceramic Floor Tiles
To clean Porcelain tiles I would normally just apply Tile Doctor Pro-Clean however given the amount of dirt in the tile we needed all the help we could get so the Pro-Clean was mixed 50/50 with NanoTech Ultra Clean which results in the creation of a powerful tile cleaner that contains Nano sized abrasive particles that can penetrate deep into the dirt. The cleaning solution was left to dwell on the surface of the tile for twenty minutes before scrubbing the floor with rotary machine fitted with a black scrubbing pad. You could see the dirt coming out of the floor at this point so once the whole floor was scrubbed I switched to a Rotovac machine which applies and removes water at high pressure to remove the soil and rinse the floor at the same time.
You can see from the photograph above which was taken with the Rotovac machine in use the difference in the tiled floor.
