I am back two years later with another stain:(. Someone left a tray with some gravy underneath that had Tumeric in it on my counter and it has left stains all over in different areas. My counter top is Taj Mahal Quartzite. I cook a lot and have never had an issue with any food stains prior to this. Unfortunately I think the tray sat for a few hours on the countertop and seeped in. Any recommendations that have been tried and tested? I used a poultice in the past for another stain made from dichotomous earth and 40 clear peroxide. But I do not know if it’s ok to use on an oil based Tumeric stain:(. Please help!

We do not have edge staining. The only place we notice any change in color is along the seam where our faucet is. And mostly when my MIL decides to wash dishes at the holidays. LOL. Our dish towels are nearby and I just wipe up any excess water. If water does get through the seam and discolors the stone, it dries within a day and it’s back to normal. No issues like what is reported here. Our quartzite was labeled as Mykonos... looks to be similar to a Macaubus. We’ve had it almost a year and a half. We seal it twice a year. Takes about an hour to do (more so with dry time between sealant applications), but I can easily multitask and do other things, honestly it is not a big deal at all.

Based on my very limited experience, I would guess that the stone was still wet from water used during fabrication and that it was sealed before it had a chance to completely dry out. The darker parts are probably where more water was absorbed and the lighter parts are where less water was absorbed. We had a couple of light colored quartzite slabs that we did not realize the fabricator was storing outside. When it came time for fabrication to select what part of the stone to use, our stones were very splotchy -- it turned out it was because they were wet from the weeks of torrential rain -- the denser parts of the stone absorbed less water and looked very white in comparison to the less dense parts that had absorbed a lot of water. The stones were extremely splotchy looking. We had to wait a month for them to dry out -- the darker parts lightened up as the stone was drying out and the coloring became more uniform looking again. Once the stones are sealed, it becomes much harder for any water trapped inside to evaporate. BTW, I did an experiment with a small sample of our quartzite that our fabricator had chipped off for us a long time back to take around to do our tile and paint selections -- I put it in a cup that had a small amount of water at the bottom (most of the stone was above the water level)-- within just a few minutes, the water had wicked up into the stone way above the water level in the cup and the stone became much darker where the water got absorbed.

@joseph_corlett, Does a positive reveal mean the countertop sticks out a bit into the sink? That is how my current sink in a different house is mounted. In reading some other posts, I am getting leary of a light colored sink due to chance of staining although I love the look. Are certain brands more stain resistant than others? I don't let food sit in the sink. I'm also wondering if quartz is a bad idea for us vs granite which we currently have. Occasionally I wash my small dog in the sink as I can't physically lean over a bathtub to wash him and I worry about quartz getting scratched by the dog's nails. Thanks so much for your input.
