Porcelain tiles are very hard wearing and a great choice for kitchens where they are likely to see a large amount of foot traffic, you do need to be careful however if they are the micro porous porcelain which as the name suggests are slightly porous and can trap dirt and become difficult to clean. The other problem you are likely to have with any tiled floor is the grout which has a porous top layer that can become stained.
This was the case with the kitchen floor tiles at this house in Glasgow where you can see from the photograph below the improvement in the centre of the floor where we had test cleaned the tiles; the grout used was dark in colour which hides the dirt so unfortunately you cannot tell from the photograph the improvement in the grout.
Deep Cleaning Porcelain Tile and Grout
To get the tile and grout really clean a strong dilution of Tile Doctor Pro-Clean was applied and left to soak in to the surface for around ten minutes before scrubbing it into the tile with a bonnet machine fitted with a black scrubbing pad and also a stiff hand brush along the grout lines. This was then rinsed away with warm water all of which was removed by a wet Vacuum. This whole process was repeated three times until we were satisfied that the tile and the grout was looking new again after which the floor was given a final wash with Tile Doctor Neutral Cleaner and then dried as much as possible using the wet vacuum.
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.
