Can clean won't clean

[HawkEye244]

I've cleaned the bathroom tiles 2-3 times now and despite working hard at it a dusty film grows back on them no matter how many times I clean them. Help

Are these new tiles? If so try a white toweling cloth and Methylated spirits.

sounds like grout residue. can you tell us the kind of tiles e.g. natural stone, porcelain, ceramic?

you can try buffing with a dry cloth, if that doesnt work then depending on the type of tile you'll need a very mild acid based cleaner such as lithofin cement away

yep ok. you need a grout film remover if the dry cloth buffing doesnt work. its a common issue. ltp, lithofin, hg or fila all do one
