You can try using a hair dryer to see if you can speed up the drying.

Do you know if they sealed the stone? Once the stain is out, sealing is what can hopefully prevent that from happening again.

I'm sorry that happened to you - it is a gorgeous stone, and unfortunately quartzites can be tricky when it comes to porosity and sealing.

Karin_mt..... I paid for them to seal it but I’m now questioning it. Is there any trick for sealing quartzite?? Does it need extra??

I'd take a Bernz-O-Matic to it.

What is that??

If it's an oil stain, try an acetone soaked paper towel covered in Saran Wrap with the edges taped.

They already did a poultice treatment

It may need extra thorough sealing - some quartzites are fairly porous and this problem crops up here with some regularity.

Not all quartzites are prone to this. Here's an article that explains why it happens.

Thank you!! That was very helpful! Clearly mine is a more Porous stone. I was extremely thorough in my research beforehand. I brought glass to stone yards to do the “scratch test”. I brought samples home of various stones and let lemon juice, olive oil and red wine sit overnight. Of course Taj Majal wiped up right away so that convinced me quartzite was the way to go. That article mentioned Taj Mahal and fully explains to me why that is different from my white lux quartzite. Do you know anything more about specifically sealing this type of porous quartzite in case my fabricator doesn’t? Is there a specific brand? One just for quartzite?

You don’t have to have the fabricator seal your counters. It is not difficult to do. It may require several coats to get a proper seal when dealing with more porous materials. You just have to make sure to use a good stone counter sealer. Look into Tenax Proseal. Make sure you get the stains out first and area is dry before sealing.

There isn't a sealer specifically for quartzite, but there are several good sealers. One that was recommended when I was testing various materials is Dry Treat Stain Proof impregnating sealer.

I'm not that knowledgeable about the details of sealing - sorry! There are others here who work with natural stone OldRyder is one of them. He might have more insight for you. Vinmarks also had good advice too!

"They already did a poultice treatment"

Yeah, and it didn't turn out so hot. Just because you've tried one thing doesn't mean you should't try something else.

Mcc, how long did it take for your countertops to ultimately dry from the poultice?

A little too long. After months and months of dealing with this, I have noticed that the stains are less noticeable (and eventually fade away) than the actual poltice drying process. However, I do lay a kitchen towel down on my counter when I’m cooking with oil

Wow that’s so frustrating. Sorry to hear. Do you mean that the poultice wet stain never went away fully?

Oh no it definitely goes away!

Ok that’s good to hear. I was thinking I ruined my countertops by trying a poultice. It’s been 1 day of drying and not much change. I agree with you - next time I will just leave the stain alone. It was much less scary than this poultice moisture.

Do you remember if it was a week or a month (or longer) for the poultice moisture stain to dry?

Thank you!

I also have leathered white lux and I find it stains from oil. @Mcc have you found a good sealer for this specific stone?

@Debra Tenax Proseal.
