Efflorescence issue

[abtilequestions]

Hi! Hoping for some advice on fixing this efflorescence. Only have this issue in the shower. Have the same tiles elsewhere without issue. Have tried vinegar, have tried dravco tile cleaner and have tried 12% hydrogen peroxide. Each one has made no change. Each one gave a good scrub with.

Try to scrape a small portion with a Stanley blade, see how it goes.

We have some good threads on this use the forum search. I'm just finishing off this blog and am off to sleep. Will be back in about 9 hours (I'm also on school run).

Looks more like lime residue to me tbh. Are there any powdery deposits or is it just staining?

It’s just staining. No powder at all. I’ve tried CLR so if it was lime I’d think it would have improved.

There is water sitting on the floor, no pitch down towards the drain. You can stain the grout joints, or you can rake out and regrout.

Is that grouted ? If it is that needs to be re grouted as there is many holes in the joints that will lead too a failed floor especially on a wet tray floor. As for the residue go too a tile shop and buy some tile acid let it sit on the affected areas then wash off.
