Granite was sealed and is now hazy - how do I clean it?

The title says it all. The stone fabricator sealed my Ubatuba, and now it's hazy. How do I clean off the haze?

Bumping to see if anyone will answer. I was sure I'd seen the answer to this on this forum awhile ago, before I had hazy granite in *my* kitchen ...

Your UT should NOT have been sealed :( It's too dense. Sealer can't penetrate the surface. I can't remember the exact details and products needed but acetone and steel wool comes to mind. I'd put out a APB for Bill Vincent and/or go to the John Bridge tile forum and ask them how to remove the sealer from your granite. Sorry :(

That is correct. Uba Tuba does not need sealing and should not have been. Any chance getting the fabricator back and removing the sealer at his own expense? He's the one that messed it up. NancyLouise

Oh I am so sorry you are going through this.
I was told by our installer to not overseal with home
seal kits. Hazy appearance is oversealing the granite.
To avoid this problem we needed to wash the granite and
let it dry for 6 to 10 hours before sealing it.
Otherwise a hazy cloudy appearance will show up.
I am not a granite guru just a granite owner.

Here is a link that might explain what is going.
I have no idea how to fix it.

Q. Why do my Granite countertops look hazy?
A. This is usually caused by cleaning the surfaces of your Granite countertops but not completely drying it. It may also be caused by using too much soap when cleaning your Granite countertops. We recommend using a damp towel followed by a dry towel to remove the haze. Sealing with a water-based sealer can also leave Granite countertops looking cloudy.

Sometimes the haze could be excess sealer (any that wasn't absorbed if it's a penetrating sealer) that dried on the surface. If that's the case, you could try buff it off w/ a piece of 0000 or 000 steel wool. I have used 00 on ours without scratching, but don't know your granite well enough to tell you to use that (you could try it in an inconspicuous spot if the 000 and 0000 are too "fine" to do anything).

As per our stoneyard's instructions, we'd applied our sealer (KR-33; definitely not water-based), and then left it on to "cure" overnight--buffing off any haze 24 hrs later (just dried residue, non-sticky BTW) with the steel wool. Some spots took a little light elbow grease, but it all came off.

Try emailing one of the following GWers about this. They're both "in the industry" and should be able to help:

* StoneGirl (see her email on her page: https://auth.gardenweb.com/members/stonegirl)

and/or

* Kevin (info@azschoolofrock.com) (mention that you're from GW)

For either/both, include the link to this thread in your email:

CLean it with acetone and allow to dry.

Wow. A lot of misinformation here. Cat mom is on the money. The haze is the sealer that was allowed to dry. You usually can remove it by applying the sealer again and wiping it all off (yes, lots of wasted sealer). Let the fabricator fix the problem.

On a side note... ALL natural stone is porous to some degree. Uba Tuba is a rather dense stone but I still recommend to seal it.

Just FYI - we tried the use sealer to remove sealer trick and it didn't work. Acetone did the job, though (and is much cheaper). You can get it at HD in the paint section.

I've never heard of anyone recommending to seal Uba Tuba.
