grout haze on black galaxy granite

Q. I just put a laticrete unsanded grout on my granite. After two days of scrubbing, I still have a haze. Trying vinegar, kinda working, but not enough. When and If I ever do get it cleaned off, what product can I use that will give black galaxy tiles a wet look? they are on a wall and on a floor surounding a wood stove. Thanks, Cheryl
 
A. Hi Cheryl. To get the haze off you will need a stronger acid such as phosporic acid. It is bottled as a grout residue remover or you could use a soap film remover for natural stone such as MB-3 Soap Film Remover and a scrub brush.
 
It wouldn't hurt to have a pro do it. (You can find a good one in your area by visiting the Find a PRO section at www.stoneandtilepros.com)
 
As far as giving the black galaxy a wet look, unless your black galaxy has a honed finish it should have a highly polished luster and no reason to enhance the look. Black galaxy, just so you know, when polished is non-porous and does not need to be sealed. If it is honed then you could use an enhancer like MB Stonecare MB-6 to deepen the color of the stone. You will have to apply it carefully and follow the directions. If you have any questions give us a call.
