Cleaning non-slip Ceramic Tiles
Judging by the level of soil build-up on the floor I mixed a solution of one part Tile Doctor Pro-Clean (a high alkaline cleaner) with five parts of water. This was then left to dwell on the tiles so the solution could seep into the crevices of the non-slip tile breaking it down and making it easier to clean.
I agitated the solution using scrubbing pads to remove the soil which once the dirty cleaning solution was rinsed away and removed using a wet vacuum made a dramatic difference to the overall appearance of the floor.
Removing Grout Smears from Ceramic Tiles
The floor looked much better however now it was clean I could see a film of grout haze residue on the surface of many of the tiles which had been left over from the initial installation. To tackle this problem I applied Tile Doctor Grout Clean-Up which along with grout haze this product can also remove rust stains and other mineral deposits. I was now happy with the condition of the ceramic tile and grout and after another rinse with water I promptly force dried the floor with a special fan in order to get the toilet ready for use again. You only need to look at the before and after photos to see the difference!
