Help with stained granite hearth

4 years ago

We are building a house. We chose a granite for our fireplace surround/hearth. The granite is called Silver Spring (at least here, in Kansas City). I have a friend who has this granite as the top of a large island in a mudroom/laundry area. When the granite got installed, it had dark circles in the stone where it looked like the handles the installers use left a mark. The installers had to give us a new piece of granite b/c they didn't come out. Now, we have marks again that look like rectangles. I believe two kitchen drawers were set on the slab for a few days. I don't know why that would leave a mark. Does anyone have any idea on what to do about this? Seems crazy with granite. This isn't a tempermental marble. I guess maybe it is a tempermental granite! If you have any idea on how to get out these dark marks, I would love to hear it. Or, has anyone had anything like this happen on granite? Thanks in advance. Photos of both instances below.

"Stain Reaper" sounds like a good costume to wear to the Houzz Halloween party.

Joseph, if you recommend this product, I will try it. Do you have a brand you recommend? Also, we do wonder if it was an adhesive.

Your stone looks like unoiked soapstone to me. Possibly oil marks. Try dawn dishwashing detergent.

Sorry, but it doesn't look anything like an unoiled soapstone. Also, since soapstone is not porous and does not stain, it would not have those marks.

Can you get the fabricator to come back and fix this, or even replace that piece?

I think @Joseph Corlett, LLC said google a poultice because there is no brand. You make it yourself and apply it and let it sit. There is one well-known one by a stone expert named Maurizio Bertoli (he has sadly passed away). I'll see if I can find it.

Thanks to all of you. We have already had this replaced once...I don't think I can have the stone people replace it again unless I can prove their installation was the problem. Joseph, I looked at the site, Do you think the Stain Reaper is the product I need?

Get pure acetone from your local Sally's Beauty Supply and mix little by little with baking soda until it's the consistency of peanut butter. Put over the stained areas, cover with plastic wrap and put painter's tape around the edges. Leave on a couple of days. Remove the plastic wrap and allow the acetone and baking soda to air dry. As it evaporates, it will *hopefully* pull whatever has soaked into the stone out with it. I did this several times in a previous kitchen.
