I was called out to clean a Porcelain tiled floor at a newly built property in Winwick near Huntingdon. The tiles were heavily marked with grout and dirt and were impossible to get clean. To make things worse the tiles were pale, almost white, in colour which made the staining more obvious. It was clear to me that the builder had not managed to polish off all the grout after tiling and this had now set hard on the surface.
This is a very common problem known as Grout Haze and fortunately there is a solution, in that it can be removed by giving the tiles a rinse with an acidic tile cleaner called Tile Doctor Grout Clean-up. To prove the point, I carried out a quick demonstration so the new owners could appreciate the difference.
I always like to test porcelain tiles for a reaction to acid prior to commencing work as acidic cleaners can have a negative effect on some types of polished porcelain however this one had a textured feel to it so there was no issue.
Removing Grout Haze from Pale Porcelain Kitchen Tiles
The test went well so having got the go head I began by first cleaning the tiles with a medium dilution of Tile Doctor Pro-Clean, this was left for about ten minutes before being worked into the tile with a black scrubbing pad fitted to a rotary machine. I also used a stiff brush along the grout lines to make sure the grout was as clean as the tile.
This process generates a lot of soiling which was then extracted using a truck mount machine. By Truck Mount I’m referring to a powerful cleaning machine that’s fitted into my van, it blasts the floor with hot water and then immediately extracts it using an equally powerful vacuum to grey tank in the vehicle, it’s incredibly effective and leaves very little water on the floor afterwards.
The next step was to tackle the grout haze and this is done as before by Acid Washing the floor using a dilution of Tile Doctor Grout Clean-up and scrubbing into the tile as before. Again, the resultant soils were extracted as before using the truck mount.
Sealing Pale Porcelain Kitchen Tiles and Grout
The floor was then speed dried using Dripods which are small horizontal fans designed to blow air downwards and ideal for drying carpets and hard floors. Once dry, a coat of Tile Doctor Ultra-Seal was applied, left to dry and any excess buffed away with a White pad.
The work was completed in one day and completely transformed the floor much to the delight of my customer who left the following message in a subsequent email:
I’m pleased to say I have since returned to the neighbourhood and completed another identical grout removal job at a neighbour’s property who had the same issue with builder.
