I've recently bought a house which was previously owned by a guy who obviously loved DIY, but might not have been quite as good at it as he thought
The bathroom has been tiled from floor to ceiling - some of the grout is needing replaced (which is easy enough) - but the tiles are needing cleaned.
Specifically - it looks like when the guy was removing the excess grout during fitting - he didn't clean the sponge or tile surface properly, and the tiles have a kind of white sandy texture on their surface - it makes them very difficult to clean properly (and almost impossible to shine)
Is there an easy way to remove the thin film of grout from the tile surface, so that I can then clean and buff the tile surface? A chemical or something perhaps that can make it easier to remove?
