Any ideas on how to clean these?!

Sorry for the very boring thread! I have some dark grey tiles in a wet room and, due to living in a hard water area, they always look horrible. I don’t know exactly what they’re made of - something slatey but not slate perhaps? .

I’ve washed them today and this is what they look like. I just can never get them looking good.

You could spray the tiles with limescale remover, and leave it to work. Then rinse.

Or if it’s a very large area, lay kitchen roll all over the tiles and spray the paper with white malt vinegar so that it’s soaked. Vinegar is mild acid and dissolves the limescale residue.

There is a company called HG who make all sorts cleaners for stone floors, they sell through Lakeland.

Are you sure it’s not slate?

Limescale remover. I find viakal the best. They do it in gel form too. Pour over, wipe so it covers all the tiles and leave for an hour before rinsing.

I had a slate topped vanity unit and kitchen shelf thing, looked lovely, super smooth, but could never get water marks out. Not very helpful sorry, unless it helps you id it as slate!

Actually it may have been soap marks. Limescale remover didn't help. (It does for everything else!)

Thank you for the replies. I’ve tried various limescale removers but not had much luck. It’s weird because this has only been happening for about four months. I’ll give the kitchen roll suggestion a try. Thanks again :)

If your tiles are slate and have not been treated with any oils, it will suck up everything. Acids are not recommended. Try putting a thin layer of linseed oil on a little patch and see if it cancels out the white, remove any excess oil after 15 min.

Stone oils bought specifically for this is basically linseed oil sometimes mixed with white spirit. (Much more expensive).

Thank you madam, I’ll get some linseed oil and report back (because I’m sure you’ll all be desperate to know the outcome!)

I'm holding my breath . Good luck.
