Hi there
Does anyone know how I can get rid of mould that has seeped from dingy grout onto the nearby limestone tiles. I tried applying white vinegar this morning, to no avail, and have tried bleach too, and it's no go.
I know that limestone is porous so even though we sealed the tiles when the bathroom was done (6 years ago), we're not meant to use certain cleaning products.
Either way, the mould is annoying me and I want to kill it. Any suggestions gratefully received!
