Trying to help a customer out on an issue in a room I didn't actually tile. He has a downstairs cloakroom room with large format tiles, grey stone effect print. The room above had a bad leak and the water from a poorly tightened heating pipe ran down below. The end result is what you could call a shading in certain areas when dry. I've never come across anything like it to be honest.
Showing photos here is a bit pointless because the tile pattern hides it in that format, but you can see it in person and there is an issue. My thoughts were it was something in the heating pipes, inhibitor residue, or just general muck, but it's a new system and inhibitors hadn't been added at that point. Which means it's basically just hot water that's stained them. Odd
Wondered if anyone had come across similar and could recommend a cleaner to try
