I have a walk-in shower with dark-grey tiles; some water landed and stayed outside the usual shower area (a drip-tray sized area ) and is an ugly pale-white shade now.
I need to fix. How? I've heard of white vinegar solutions but has anyone tried this? (Added to which, I'm unsure of my local store (overseas) has white vinegar).
