Removing stain from white quartz

[Tilerbhoy]

the wife decided to clean contents from inside oven, the ones where you put it all in a bag and pour in chemicals and leave overnight, well the bag had a hole in it and she decided to put a towel down and stick it on the tiles without me knowing.
Came down in the morning looked it at it and said WTF, pulled it off the tiles and there’s a big rusty stain about 600 by 400 wide over 4 tiles.
The problem is it’s in the middle of a 20m floor with ufh.
I could have killed her
She’s tried bleaching it but it’s came back and now the area feels like sandpaper.
Any suggestions?

The likelyhood is you've chemically melted the Quartz with, it's not a stain as such it's actually altered the composition of the material. The oven cleaners are caustic and too much for man made quartz to deal with.

The only way you get rid of it is to grind and re polish, which is a very specialist job on quartz, or replace it.

The reality is if you have accidental damage cover on your home insurance this is a rip out and replace job.

I have pure white quartz worktops and got rust stains on it, after trying many different recomendations from my stone man I used collit bang limescale. Worked a treat and not a mark left

Bang and the stain is gone.......along with the polished surface

Hasnt affected my worktops, was concerned about that myself. Came down to rust stain or give it a go
