Tile cleaning

By | May 12, 2017

Hi, we have just had an ensuite tiled and the tilers did not do a very good job cleaning up the floor grout. The floor tiles are a matt textured tile and there is a thin layer of powdery grout left in places that will not come off with standard domestic cleaners. The size is approximately 1.8 x 4m with free standing bath, vanity and toilet in place. Is this something you can help with?
