Granite Countertop Dull Around Sink

by Kelly

QUESTION:

I have a Emerald Pearl granite countertop in my kitchen that is 8 years old. It looks great with the exception of some dullness around the sink.


In particular, it's dull in the area where I keep my dish rack for hand washed dishes.

Because the rack isn't that large, I've definitely left wet pots/pans on the granite itself. I've used Granite Gold daily cleaner and polish and it hasn't taken care of the dullness.

Any suggestions? Also, I have a small water stain around the base of the faucet that I'd like to remove.

What is the best method to polish granite, remove the stain and cleaner? Thank you.

ANSWER:

This could be a couple granite counter top maintenance issues.

Granite countertops will not etch easily under normal household use, however, some city water supplies can be slightly acidic.

And even though granite does not readily etch, constant exposure over time to any acidic substance could etch the surface resulting in the dull appearance. And eight years could be enough time.

The fact that you are seeing the "water stain" and dullness around the faucet and under the dish rack where water will typically accumulate is the key clue here.

If it is etching you'll need to call in a stone restoration professional to re-finish the etched areas. Since granite is so hard, there isn't any DIY products or methods for you as a homeowner to use.

The second possibility is that you have soap scum build up, which doesn't explain the "water stain" around the faucet too well, but could explain the dullness under the dish rack.

Dish soap or soap of any kind requires A LOT of water to truly rinse. Most often soapy residue still remains on rinsed surfaces (like pots, pans, plates) and could drip off onto your countertop.

Soapy build-up is why we recommend that you do NOT use soap for granite counter top maintenance or cleaning... you get a dull build up.

You should use only products safe for cleaning granite & marble.

If it is soap scum, you should be able to scratch it off a bit with a fingernail. If you can't seem to scratch any off, then it is likely etching. Soap scum is tenacious and a general granite cleaner usually will not take it off.

For removing soap scum use the Soap Scum / Hard Water Remover.

A third possibility would be etching of a granite sealer residue on the surface, but you would have noticed this right away (not after eight years) and you'd almost certainly see it over other food prep areas, etc., so this is not likely.

And Emerald Pearl is a tough granite (actually syenite) that would typically only etch under extreme circumstances or exposure to highly acidic substances, so dense it's nearly impossible to stain and rarely presents a granite counter top maintenance issue.

My bet is even though your water could be acidic and theoretically it is possible that 8-years of exposure could etch the granite... it's soap scum build-up.

If the Soap Scum Remover doesn't clean it off, then it is etching.

Granite around sink coarse and lost gloss
by: Jim

Our Madura Gold Granite countertop around the stainless steel sink has rubbed out and become coarse across from the faucet. Presumably the cause is from holding pots/pans against that area for leverage while scrubbing it. Any fixes besides getting a pro to look at it? Once the gloss there has gone, is there risk of water seeping into the entire area? Thanks

==== Countertop Specialty comment:

Wow, that's a lot of scrubbing pans! Granite is very durable and I imagine this occurred over many years (unless it is a very small and focused area that receive heavy use).

If you are certain the granite was once perfectly shiny and now has become dull and more raw, then yes... it is likely due to the combination of lots of water around the sink and the physical abrasion from the pots and pans wearing down the surface finish.

You'll have to hire a stone restoration pro to repolish the area. Then devise a different method for washing your pans. Maybe just put a cutting board down and set the pots on that, or a folded towel.

Dullness around sink edge
by: Cory

I have bianco antico granite counters in my kitchen. It is recently new (4 months since installation).

I have an inset stainless steel sink, and the edge of the granite where it is cut for the sink is rather dull and almost looks discolored.

We have a water softener, and we have not yet sealed our granite (nor do we know if we should??).

We've done the water test and it seems our granite is less porous. However, not quite sure what to do with the discoloration/dulling around the sink edge. Hopefully it wasn't a problem with how the granite was cut.

===== Countertop Specialty:

White granite countertops will typically need sealing, but definitely go by what the water test shows.

Edge dullness can often result with a resined granite where the top surface looks a bit darker than the edges.

Soap film or hard water can be an issue with build-up making the surface look dull, but this would happen on the surface around the sink as well and not just on the sink edges.

Hard to say exactly without seeing it. Send us this question via our Contact Us Form and we'll follow up with you. Take some photos that you can send us after we respond to the "Contact" form.

Dull Black Granite over dishwasher
by: Anonymous

I have just had a Black Pearl granite countertop installed. I love it. But now I have run my dishwasher a few times. And the edges over it are dull on my counters. Is this poor or wrong sealer? Is this something I will have happen no matter what?

===== ADMIN COMMENT:

Well, steam can wear on stone and make a polished surface dull, however, this process usually takes some time and usually on softer stones like marble.

Black pearl granite is typically pretty dense and usually does not need sealing. Any stone that is naturally dense, does not need sealing and should not have a sealer applied.

Sealers applied to granite countertops that do not need sealing usually end up with a hazy dull residue covering the surface.

Possibly that did not happen in your case, but I'd bet it is the sealer that is being affected and not the granite countertop itself.

But have your installer come take a look and/or a stone restoration pro.
