Haze from Sealing Granite Countertops


I just sealed my new granite countertops and I'm experiencing a haze or a film on the surface.

How do I clean it off?


A haze or residue left after sealing granite countertops (or marble, floor tile, or any natural stone) is the result of the sealer drying on the surface, which should not happen.

Hazy streaks after sealing can occur for two reasons:

1. The granite countertops did not need sealing. Many granite colors are naturally dense, non-absorbent and cannot (should not) be sealed. This is also true with some marble, travertine, etc.

I know you read and hear that "all" granite "must" be sealed, but that is flat out false. If a sealer is applied when not needed, it just sits on top without absorbing and leaves a hazy, streaky or blotchy granite sealer residue.

Luckily, it is easy to determine if and/or when your granite countertop (or any natural stone) needs sealing by simply performing the water test for sealing granite countertops.

2. The granite sealer was improperly applied. If the granite countertops did need sealing but the sealer was (incorrectly) left to dry on the surface, you'll get the streaky-hazy residue.

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 product applied, so no sealer residue remains on the surface.... but it is still a 100% incorrect way to apply an impregnating stone sealer.

Never blindly slap on a sealer. First, always determine if the granite countertop (or any stone or tile) 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!

How To Remove Granite Sealer Residue:

Now that you have the streaks, you'll have to try and remove the sealer residue from the surface.

Remember, stone sealers are designed to remain on the stone for as long as possible and take a relatively long time (a few years) to break down or wear away.

Thus, removing granite sealer residue that has dried or cured on the surface can be tricky and troublesome.

Here's a few potential solutions to try:

You may get lucky scrubbing with steel wool or a magic eraser. Do this on granite or honed marble & travertine only. Such abrasives could scratch a polished finish on marble or travertine.

In most cases, you'll have to strip off the sealer residue using certain solvents. The exact choice (acetone, mineral spirits, methylene chloride) will depend on how tough it is to remove.

You'll find complete instructions in the All About Sealing Granite & Marble ebook.

After stripping off the haze you may need to re-seal the granite, but of course you will test it first to see if it indeed needs a stone sealer ... or not.

granite countertop haze around sink
by: Ron

I have had granite counters in my last 3 homes. The granite in my present kitchen has a haze on it right at the apron of the kitchen sink. It looks lousy.

I have had it stripped, & polished 3x & the shine lasts 3 days.

I live in SE FL. I lived in NYC for many years with Wilsonart laminate counters that were 15 years old when I sold my condo and looked like they had just been installed.

My next house will be BACK to laminate or Corian. I am OVER cleaning & polishing granite!!!

==== Countertop Specialty comment:

Very unlikely that the haze around the sink is a problem with the granite countertop. It's almost certainly due to mineral deposits from hard water.

Stripping and polishing will remove this, but as soon as any water dries on the granite it will leave behind hazy mineral deposits.

Hard water can be difficult to remove with standard cleaners.

You may be able to remove buildup with 0000 steel wool, but typically you'll also need a specialized cleaner like this Hard Water / Soap Scum Remover made specifically for use on marble & granite countertops.

You'd get this build-up no matter what type of countertop material is installed.

Spotty film on black galaxy granite
by: Mike

Just installed new black galaxy counters in a new kitchen and there is a spotty film under the shine. I was told by the installer it needs to be sealed but sealing didn't take the film away . It almost looks like the granite was left out in the rain and it appears to be water stains under the finish.

===== Countertop Specialty comment:

Typically, a haze or film on granite is from improper application of a sealer. Sealer residue will leave a streaky haze.

Usually, black galaxy granite will not need to be sealed since it is naturally stain-resistant and a sealer will not clean or remove anything.

A "spotty" haze is somewhat curious. It could be hard water deposits. Tough to know without seeing it or knowing the exact history.

Scrubbing with acetone and 0000-grade steel wool may remove it. Also, note that the "shine" is not on top of the granite. It is part of the granite. The granite itself has been ground or sanded smooth to a shiny finish.

Magic Eraser

Thanks so much for your recommendation of Magic Eraser to clean the haze. Just had new granite counter tops installed and got the "haze". So relieved to have found a cure. Thanks again!

Haze on Ubatuba
by: Nick

I just had installled my counter tops with Ubatuba about a month ago.

I've noticed that only the countertop on the island has a haze to it.

The company came back and applied more sealant but this did not work. They had use Adria Protection sealer. Any ideas?

==== Countertop Specialty comment:

Uba Tuba granite is usually very dense and very low absorbency so doesn't need a sealer. You need to test it to be sure, but typically does not need it.

The haze is probably from the sealer they put on the first time. Applying more sealer, scrubbing, and then wiping off all excess and drying can sometimes remove the haze, but only if done within a day or two of the original application.

You'll likely need to use a potent solvent like methylene chloride to strip off the hazy film.

Magic Eraser worked
by: NY5

Thanks so much for all the responses here. I too used Magic Eraser and it removed all the residue that looks like it might have been from improper sealing.

Hazy Dull Granite Countertop with Water Stains

by Carol Laffite
(Lancaster, CA)


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 can't see it when you look DOWN at it, only when you look at it from the side. It's a combination of streaks and now water stains or spots and glass rings too.

I've only had the house one year. I don't know if it was ever 'sealed'. I've never sealed it. What can I buy to fix this?


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 residue from improper sealing technique.

If a sealer is applied on a granite countertop (or any type of natural stone) 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, blotchy, or 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 sealer residue can be difficult. You'll likely have to use powerful solvent like methylene chloride to strip it off.

Despite what you may read that sealing granite countertops must be done on all granite every year, it's not true.

Many granite colors need a sealer applied, however, very few granite countertops will need annual resealing.

Frequency for applying a granite sealer depends on many variables, but most surfaces will go 3-5 years before needing more sealer. Some can go 10 years and if you use a permanent granite sealer like Senguard, you'll never have to re-seal.

The "water stains" and glass rings are not actually from water and they are not stains. These are from acidic substances etching the sealer residue on the surface... not the granite itself.

Follow the e-book instructions (link near top) on how to remove sealer residue and you should get rid of the water marks and get your shine back!

Hazy Ghost Spot on Black Granite

by joe moreno
(greeley co.)


Our black granite countertop has hazy rings and a hazy ghost spot. What can we do to clean it up?


Used to be that 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 them more black and this dye will etch creating the "ghost spots" you describe.

Improper sealer application could be to blame as well. Putting a sealer on a non-absorbent black granite countertop is trouble.

The sealer remains on the surface rather than absorbing into the stone and forms a film that can etch creating the rings and dull spots.

In any case, you'll need to remove whatever is on the surface using solvents. Try acetone or methylene chloride (found in paint strippers).

If the MC doesn't work, then likely you have a a rare granite that etches but most likely it is a sealer residue or doctoring dye issue.

Haze On New Granite Countertops


I had Santa Cecilia granite countertops 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 and applying a granite sealer does not present problems with absorption which can result in problematic film.

A common sealer application error is to let the sealer dry on the surface. This often results in the streaky haze.

The glass rings are from acidic substances etching the sealer residue left on the countertop surface (and not the granite itself).

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.

Why Is My Sealed Granite Blotchy?

by Mike Doyen
(Naples FL 34105)


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 sealer. Black granite countertops are typically so dense to be essentially non-absorbent and will not stain except in extreme circumstances.

In fact, most black granite cannot be sealed since the sealer will not absorb.

When a granite sealer is applied to a black granite like Absolute Black or Black Galaxy it just sits on top until it dries leaving a dull hazy, streaky, or blotchy sealer residue on top.

Now, if the sealer is wiped off completely prior to drying like it should be, then you may not develop any problem. It's not likely the sealer absorbed much if at all into black granite, but wiping down until dry at least avoids creating a haze problem.

If applied and left to dry, it is possible that some sealer absorbed in some spots and in other areas it didn't.

Anyway, here's how to remove sealer residue:

Strip it off by washing and scrubbing with methylene chloride. You may have luck re-applying the sealer to try and get it to re-absorb the dried sealer then remove all excess and dry completely. But may be too late.

Info about sealers, how to properly seal stone, and how to remove granite sealer residue is in the Sealing Granite & Marble ebook.

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.

All you need to do to determine if any stone needs sealing is to water test for sealing granite countertops the surface in several places.

dull granite
by: carolina lady

Just purchased a home 3 years old and the black granite counters in kitchen (especially sink area) are dull and hazy.

Have cleaned with soap and water and they will not shine like all other granite counters I have had.

Have just pulled out nasty caulking and wondering what steps to take to make this granite pop. Should the next step be caulk or more cleaning?

Need advice on products to use for both caulk and cleaning. Please help!! Thanks.

fixing dull granite haze
by: Ryan

Carolina lady... almost certainly your granite was improperly sealed. The dull haze is the sealer residue dried on the surface. It must be stripped off. Usually this is a nasty job using the solvent methylene chloride.

Marble counters stain
by: Heman

Hi, I'm a granite and marble installer. A customer came to me with a problem.

She has a honed Calacatta gold marble island. Every time she has a party she would have rings on here counter top.

Is there anything that can be done. We have honed it again and put sealer back on it but it still gets rings and we are afraid to take the sealer off cause it could stain.

The ring the glass make is not clearly round it's more like when the light hits it it's a dull round spot like when you put your fingers on black honed granite. Any advice?

===== Countertop Specialty comment:

Yes, marble is sensitive to acids like wine, coffee, fruit juices, etc. Such drinks are often served at parties and the acids in the drinks corrode and etch the marble leaving the dull rings.

Sealing won't prevent etching. An etch mark is not a stain. It is physical damage to the marble, so it must be refinished. Since it's a honed surface you can sand them out or just re-hone it every so often.

Removing Miracle 511 Impregnator sealer haze from Quartzite tiles
by: Anonymous


We have laid quartzite - natural stone - not manmade quartz material ( Golden Fantasy ) tiles and the installer applied too much of the Miracle 511 impregnator sealer.

It shows sticky and streaky patches on the tiles all over.

What can we do to remove the haze? When I wrote to Miracle, if we could remove the sealer, their answer was no, that particular sealer can not be stripped off.

So, wondering what can we do to just remove the haze?


==== Countertop Specialty comment:

It often can be difficult to strip off sealer residue haze, but try scrubbing with methylene chloride. This is a powerful and noxious solvent found in paint strippers.

Protect cabinets, etc. and use carefully as instructed. Solvents won't harm granite, but this is your best shot to remove the sealer haze.
