I've just had 2 new bathrooms installed. I'm happy with the work but I'm at a loss as to how to clean my tiles. I've scrubbed them down maybe 3 times but that film keeps re-appearing in places. I even bought some residue remover but it's not that great.
I've only attempted one bathroom and I'm dreading doing the second. Does anyone have any advice to offer re cleaning pls.
Thank you
