2. The granite sealer was improperly applied. If the granite countertops did need sealing, but the granite sealer was improperly applied and left to dry on the surface you'll get the streaky haze.
The most important step when sealing granite countertops (or any stone installation) is to completely remove all excess sealer and residue from the granite countertop surface.
Unfortunately, many installers do not know this and will tell homeowners to apply a granite sealer and just leave it to soak it. Crummy advice.
They can get away with this on many stones that are porous enough to absorb all the granite sealer applied, so no surface residue remains.... but it is still 100% incorrect way to apply an impregnating sealer.
Don't just blindly slap on an impregnating sealer. You should always first determine if the granite countertop (or any stone) even needs sealing by testing the stone as noted.
When testing demonstrates that the surface "could" be sealed, then you make a judgement call (location, use, risk of staining) whether or not to actually apply a stone sealer, but you never apply a granite sealer "just to be safe".
When testing tells you the stone does not need or even cannot be sealed, then don't do it!
Now that you have the streaks, you'll have to strip the cured granite sealer residue from the surface.
I don't know how to restore it to a shiny granite countertop.
No matter what I do to 'polish' it, the haze returns as soon as I wipe off the polish. Imagine a kid covered his hands with toothpaste and rubbed it all over the counter.
You cant see it when you look DOWN at it, only when you look at it from the side. Its a combination of streaks and water spots.
What can I buy to fix this? I've only had the house one year. I don't know if it was ever 'sealed'. I've never sealed it.
Well since you are not certain what has been done to this granite countertop, I can't be certain either, however, what you describe is classic granite sealer haze from improper sealing technique.
If a sealer is applied on a granite countertop where the stone is too dense and already naturally stain-resistant, then all that will happen is the sealer will dry on the surface leaving a dull, streaky haze like you describe.
This can also happen on a granite countertop that should be sealed, but the excess sealer was not removed properly and again it dried on the surface.
I suspect this is what happened in your case. Unfortunately, removing the hazy cured granite sealer can be difficult. You'll likely have to use a potent and noxious solvent like methylene chloride.
You'll find complete information regarding sealing granite countertops and stipping sealers in the "All About Sealing e-book" (links above and below)
Despite what you may read that sealing granite countertops must be done on all granite every year, it's not true.
Many granites need a granite sealer applied, however, very few granite countertops will need annual resealing.
our black granite counter top has hazy rings and a hazy ghost spot what can we do to clean it up?
Used to be most varieties of black granite were nearly stain-proof and did not etch.
Now, many black granite countertop slabs are dog stones that will etch or have been doctored with a coloring agent to make more black and this coloring will etch creating the "ghost spots" you describe.
Or another common error is to apply a granite sealer to a non-absorbent black granite countertop. The sealer remains on the surface rather than absorbing into the stone and it's the sealer that is etching.
In any case, you'll need to strip off whatever is on the surface using methylene chloride.
In some cases lime-away works better, but this is a very acidic product, should not be used on stone in general and will etch your stone if it is indeed a dog stone with calcite.
So, best to use the MC first.
For more info on granite sealers, how to apply and how to strip granite sealers check out the All About Sealers ebook (see links on this page).
Also, you may want to test your granite with the FORENSICS Granite Test Kit to determine exactly what the problem is, so you can use the correct solution.
If the MC doesn't work, then likely you have a bad stone.
I had Santa Cecilia granite counter tops installed and I notice a haze on the granite.
Now two weeks into it I am noticing round water stains from glasses left to long on the countertop. What is this?
Most likely this is due to improper application of a granite sealer.
Santa Cecilia typically is not very dense, thus applying a granite sealer does not present problems with absorption,etc.
But if the sealer was left to dry on the surface (which is incorrect procedure), then you'll get the haze. And the glass rings are from acidic substances etching the sealer (not the granite itself) left on the countertop surface.
To solve this issue you'll need to strip the sealer off the surface using methylene chloride, which is a powerful and noxious solvent.
The "All About Sealing" e-book mentioned several times (with links) on this page details exactly how to do it.
I used SCI cleaner to clean my black granite and 8 hours later used SCI Sealor to seal it. The black granite in the bathroon (which was done 24 hours ago) looks fine. The black granite in the kitchen (which was done 6 hours ago) has black blotchy spots all over it.
Do I have a problem? If so, what should I do?
Without knowing exactly how the granite sealer was applied I can't say why one seems fine and the other blotchy, but....
Most black granite does not need a granite sealer. Black granites are typically so dense to be essentially non-absorbent and will not stain except in extreme circumstancses.
In fact, most black granite cannot be sealed since the sealer will not absorb.
What happens when a granite sealer is applied to a black granite like Absolute Black or Black Galaxy is that it just sits on top until it dries leaving a dull hazy and/or blotchy film on top.
Now, if the sealer is wiped off completely prior to drying like it should be then you may not develop any problem. Not likely the sealer has absorbed at all, but wiping down until dry at least avoids creating a problem.
If you did apply the granite sealer and just let it sit until dry it is possible that some absorbed and other areas it didn't.
Anyway, you'll need to strip off the sealer using methylene chloride. You may have luck re-applying the granite sealer to try and get it to re-absorb the dried sealer then remove, but may be too late.
You'll find complete information about granite sealers, how to properly seal stone and how to strip improperly applied sealer in the All About Sealing Granite & Marble ebook.
And for future reference not all granite or stone must be sealed. Yeah I know you read that a lot, but it comes mainly from granite sealer manufacturers.
