Cleaning Anti Slip Floor Tiles
The floor tiled need a deep clean to bring out the ingrained dirt so we applied a strong solution of Tile Doctor Pro-Clean using two parts water to one part Pro-Clean and left it to soak into the tile for twenty minutes. The solution was then scrubbed into the tile using a rotary machine fitted with a black scrubbing pad. You could see the dirt coming out the pores of the tile and the resultant soiled solution was removed using a wet vacuum before washing the tiles down with clean water.Including the ladies, gents and hallway there was a lot of floor area to cover and some of the stubborn areas had to be re-treated so it was a long job but I think you will agree the floor now looks great.
