How do I remove these stains from a quartz work surface

[Legoless]

I tried a Bicarb paste but no joy.
it’s from a wet metal baking tray being left on the surface for an embarrassingly long amount of time.

Image would help (sorry for reflections)

CIF cream and rub hard with a cloth, that's what i was advised to use and it lifts every stain including tea/coffee/curry from mine.

Cif cream. Or Bar-keepers friend cream which is seriously the best cleaning product I have ever used.

I use the pink stuff tub of paste. dry cloth rub it on wet cloth to wipe it off.

Pink stuff should get that off.

barkeepers friend powder will get it off. Spray the area with water and chuck on the powder. Leave it for ten minutes and then rub it in and the mark will come off.

Amazing thank you. Ordering now

Try barkeepers friend
