Black Galaxy Discoloration

We put in black galaxy countertops about 2 weeks ago and just noticed a ring shaped lighter discoloration in the countertop. I've tried polishing it and using steel wool #0000 but to no avail. I've also done the lemon test and it passed. Any advice on what to use to try to remove the discoloration? We have no idea what caused it. I wanted to check with an expert before putting any type of chemicals on the countertop. Findstone forum is extremely helpful because we initially thought that the countertop had not been sealed (it supposedly comes with a 15 year sealer) and we thought we would need to reseal but after reading several strings in the Findstone forum, we discovered that we should not need to ever seal them. I was hesitant to reseal because I sealed the grout on some black galaxy tiles on the floor and ended up with white streaks and a hazy appearance. A razor bland and the steel wool did take remove the streaks but I did not want to do that to my countertop. Any help you can provide would be extremely appreciated! Thanks.

 

Dear Jennifer:

I already answered your query on the findstone.com forum. ( http://forums.findstone.com/forum_posts.asp?TID=2042)

Do this: spill some vinegar on your countertop and let it sit there for a couple of minutes. Wipe if dry. If you will see a lighter discoloration, it's either the sealer or the stone was maliciously doctored. (Pay a visit at: http://www.doctoredstone.org and read all about that “marvelous” practice. There's the Chapter of my book that makes reference to that particular subject in its entirety, with pictures and all. One of the pictures is Black Galaxy.)

But, like I said in the forum, have those geniuses that applied an impregnator to norite thinking that's granite come out and remove the possible residue that it may be left behind. And let's hope that it was just that.

Send a picture or two if you could, and keep me posted. You came to the right place, and we will take care of your problem – it's a promise. But only if you're willing to fight to the bitter end.

If not, pardon me for being blunt, do not waste our time.

Where do you live?

 

Needless to say, if marblecleaning.org could have its ways, situations like this one would not exist. But we can't do anything by ourselves. We need the support of the consumers to succeed. On that spirit…
