Don't panic yet! I bet that stain will fade within a day or two. I'm sure others will weigh in here, but I have granite on my island (a dark brown) and marble on my perimeters and every stain--oil, coffee, otherwise has disappeared after a day or two, if not immediately upon wiping.

as janefan said, the stain may fade or you may need to use a poultice to remove it - you should contact stonegirl who can probably give you the best advice on your particular granite.

By the way did you test a sample of your granite before you purchased it and did you have it sealed properly? After the stain disappears, you may need additional coats of sealer. You should find out from your fabricator what sealer they used on it.

I just had honed Jet Mist installed last week and a vegetable oil bottle left on it for maybe half an hour left a mark. It had faded by morning but was still there. The fabricator came and got it out (about 99% - only I can still see the faintest mark) using acetone and then he resealed it. I am going there this week to pick up more sealer. He said I should keep sealing it and it will become more impervious to stains. I did test a leftover piece (don't know if it is sealed or not) by leaving a wet glass overnight (no mark) and an oil bottle (dark oil mark that looks permanent). Some sites have said that certain granites should not be sealed and that it you do seal them you will have problems because the sealer will interact with whatever substance you get on it and that is what is making the mark, not the actual granite. All I know is that I am VERY confused. There are a hundred different opinions about granite: how to clean it, how often (or even if) to seal it, how impervious it is, etc. I'm stressed.

Your other option is to relax a little and let it start acquiring a few blemishes. After a little while it will attain a wonderful 'lived-with' and weathered appearance. If you keep it clean, nobody is ever going to mistake the wear marks for dirt, and it's going to look a bit more human than some unnaturally pristine surface.

Keep smiling :)

KMgard, sealing the stone again after the stain has been removed should get your stone out of the "high-maintenance" category.

Jeaneteach, some granites (or stones commercially called "granite") are very non-porous and don't need to be sealed. If excess sealer is left on those, it can sometimes leave white marks when it reacts with stuff. But you should be able to see if your stone needs sealing - if you put water on it and leave it for a bit, does it bead or does some soak in? Does the water leave a dark mark that disappears as it dries? If the water soaks in or leaves a dark mark, then the stone needs to be sealed some more. The directions on the sealer should be followed to wipe off the excess after it is applied.

I agree the best thing to do is to take whatever advice you trust, try to get rid of the stain, and if you can't just relax. Any countertop that doesn't like olive oil is not a fun kitchen countertop, so if it turns out olive oil does stain it, just relax and see if in a few months of excellent cooking you can stain the whole darn thing! I bet it will look fine in a few days whatever you do. And it not it will look fine with a patina.

The one thing that bothers me about my quartz is that if it does have something happen to it (no idea what, but I am a klutz so I might think of something) it won't look beautiful in the same way that worn natural materials look beautiful, even when (especially when) they are worn. So everything has a trade off.

You've made me feel a little better. Unfortunately just leaving it isn't an option-- it's very obvious-- about a 12" long by 3" wide DARK stain. Tried one online remedy, baking soda with club soda, to no avail. Now I will try dawn with flour(???). Like I said, I guess I'm fortunate it only happened on a small piece between the stove and pantry, and now I will know to be more careful with olive oil. It just stinks that we paid all this money for a countertop when my old laminate actually worked better as a cooking surface (for me).

Oh, and I definitely need to talk with the fabricator about sealing-- they said it was pre-sealed, but cloud_swift made me realize it's not sealed enough because even water leaves dark marks until it dries. I'm not an anal person-- I like things clean, and now I feel like this granite is turning me into a panicky, OCD worry-wort. Thanks for bringing me down to earth. :)

Once it is sealed properly, you won't have to worry about using olive oil or other liquids with it. I think that if you just leave the stain alone, the olive oil may evaporate. Or you could post a question asking for directions for removing the stain on the stoneadvice.com forum. The best poultice to use depends on the type of stain and they should be able to tell you what works for olive oil. It is also important to leave it on the stain long enough covered by plastic so that the poultice can draw the stain out.

A friend of mine had the same thing happen to her the first week her granite was installed. It was a spot about 2'' x 2'' left by butter. She took dish detergent, swirled it around on the stain, covered it with saran wrap and left it over night. It was gone the next morning.

I hope that you will get your problem resolved...but this happened to my marble counter-tops and never did get it out....and I just could not stand all of the etching, so took it out....but was not happy. As the "salesperson" said, "Everyone knows you shouldn't use marble in the kitchen!".....where was he when he was so happy to sell it to me? I feel your pain and hope you have better results.

Actually marble is an excellent surface for a kitchen - particularly for rolling out dough - but marble, unlike granite, will etch no matter how much you seal it and you have to be willing to accept that it will develop a patina over time. It's not for someone who wants a pristine looking countertop.

To continue what weissman said - There are significant differences between staining and etching. A sealer can prevent staining and a stain made on an unsealed (or not well enough sealed) stone can usually be removed with the right poultice. A sealer closes the pours of s stone but it doesn't sit on top of the stone so it won't prevent etching and etching means that some of the stone has been removed changing its texture so it doesn't go away unless you repolish the stone.

kmgard: try using acetone on your stain. That's what my fabricator did yesterday and it worked! He just poured some on the stain and rubbed it in and did that a few times. One time he pooled the acetone on the stain and let it sit for a few minutes. I had the same oil stain that you are describing. Hope this helps.
I do appreciate all the other advice on this thread. I have the same granite as you do, Boxerpups, and I love it love it love it and feel as you do, like it's my baby! Tonight I was running my hands over it and felt some grittiness (which I have felt before) so I got out the razor blade given to me by my fabricator and was gently scraping at any rough patch. Then I wiped the whole island down with a towel. I realized that the grittiness is just plain 'ol dirt/dust/grime which I never noticed on my old formica because I never rubbed my hands lovingly all over it constantly!
I don't mind breaking in the granite, but at the same time I don't want a ring or stain from some substance like oil or lemon juice. I am going to keep sealing it and hope for the best! In the meantime, I do love it! (Now caring for my stainless steel Wolf cooktop is another story!)

I had a plastic soap dispenser to fade on my light granite. I did a water/baking soda poultice twice to only find the stain larger. I then proceeded to do the peroxide/ baking soda poultice. I now have yellow granite!!!! I don't know how this has happened. But what started out as a 2"×3" dark spot is now an 8"×12" yellow awful looking spot. My granite is about 5 months old. Anyone experienced this and ha e advice??
