Hi belle phoebe - no, I haven't had any issues at all like that, after about four months of use. Honestly I don't know what the fabricator used to seal it, but noting has come close to getting to our counters (no stains, etching, water rings, etc.). I will try to find out tomorrow and let you know. Good luck!

Hi again - I heard from my fabricator. They used an industrial silicone-based sealant from GranQuartz, called 413S. I'm not certain that it is available to individuals (as opposed to fabricators), but it might not hurt to ask your fabricator about it. I've pasted in a link to the product on the GranQuartz website.

I am looking forward to the answers - my white moon (luce di luna) quartzite was installed recently and I have done a few post sealer tests - ketchup, red wine and vinegar did not leave a mark but oil did. Hopefully somewhere out there is a sealer that is good at keeping oil out.

Thanks to all of you. I will investigate the possibilities and look forward to hearing back from flseadog, too. The poultice is still unresolved, since it caused more water to soak into the stone. The weather is super-humid here, so nothing is drying very quickly. I am considering trying to find something else to try and draw the water out. wonder if I could use those water-holding crystals people use for plants. Thoughts?

I did some research this morning and found this site - I like some of the non-chemical solutions.

One more - I also did searches on the John Bridge forum and found more recommendations so I feel good that at least there are solutions available.

Belle phoebe, I hope your problem has been solved. The fabricator we used said they used Stone Care International products in their shop. This seems to keep everything from staining except oil that sits for a few hours. We did have another tile and stone installation company here yesterday to do some work and they said they use nothing but the Miracle 511 products. Of the 3 subs we used for tile and stone when we were doing our new build, they did the best most meticulous work so I tend to put faith in what they say. I asked them about your problem and they said if you try the 511 you should wipe it on sparingly and to use a soft terry or microfiber towel to wipe off any excess immediately. HTH.

Hello Fellow Luce Owners! We have had our beautiful countertops installed for a week now and have discovered that yes, oil leaves a stain. I realize this is an old blog, however, if you can give me any suggestions on how to get it out, I (and my husband) would be most appreciative! The stain is is a nice ring from a cup of bacon fat drippings I left out over night ( I didn't want to pour it down my drain) :( It was sealed with a sealer that the installers said "Oh no, you can't get this stuff".
