Cleaning Victorian Tiles
We set about cleaning the tile using Tile Doctor Pro-Clean which is a powerful alkaline cleaning product that is safe to use on tile and stone. It was applied with a mop and left it to dwell on the floor for ten minutes first in order to give it chance to soak into the tile and get to work on the dirt. It was then worked into the floor using a rotary machine fitted with a black scrubbing pad, stiff hand brushes and a substantial amount of elbow grease was used to tackle the stubborn stains and along the grout lines. The soiled water was picked up with a wet and dry vacuum and once we were happy the floor was clean it was given a thorough rinse with fresh water to remove any leftover chemical and then left to dry.Sealing Victorian Tiles
Once the floor was dry we were able to seal it using four coats of Tile Doctor Seal and Go which adds a nice shine to the floor as well as providing a surface seal that will help protect the tile from stains going forward.It was quite a transformation and well worth the effort as you can see from the photographs above.
