First of all, thank you for a fantastic site.

We have a large kitchen tabletop. All we know is that it is an Engineered Stone quartz countertop. It is light grey with darker colored dots. It has a shiny surface.

During social events, we have ended up with some rather serious etchings (we didn't conduct the lime test when we moved in).

The area covered by these etchings are approx. 10x10 inches and with your fingertips you can easily feel how the shiny layer is missing in that area, as well as being matte instead of shiny. Looks terrible.

The etching came after lime and soda stains were left for hours. Water doesn't stain at all.

We are wondering how we should proceed with repairing this etched area? Any tips or links much appreciated.


Thanks for the compliment about our site. We certainly work hard to educate our viewers and provide the most comprehensive and unbiased information available about natural stone and engineered stone.

Etching and any damage to engineered stone / quartz countertops is troublesome.

The marketing for quartz countertops would suggest that engineered stone is essentially stain and damage-proof.

Unfortunately, that is not the case. It can be stained and damaged by many things. And lighter colors tend to be more susceptible to damage than darker quartz countertop colors.

Also, damage to quartz is often permanent since what gets damaged is the colored resin, which cannot be repaired or restored.

This is where stone has a big advantage over quartz countertops. Stone can almost always be repair and restored to like new. Quartz typically cannot be repaired.

The good news is that significant damage to quartz or granite is not common.

But what to do in your case?

Well, quartz is very hard like granite, so there aren't any DIY products that can be used to repair etching.

Most likely re-polishing the quartz countertop is your only possibility.

I'd suggest contacting the manufacturer (if you can determine which company made your tops) and inquire about repair options and referral to a certified tech/fabricator in your area that can work on it.

Wish I could offer more concrete and actionable suggestions, but quartz countertops can be tricky when damaged and you have to go case by case on most.

Polish gone after backsplash installed
by: Anonymous

Out beautiful, high shine smooth quartz countertoo was installed and three days later, TEC grout was used on a wall to ceiling backsplash.

My gorgeous countertop is now dull and cloudy. Same exact countertop up in my bathroom never had grout and is perfectly shiny and smooth.

What's up with the grout ruining the kitchen counter. Will polishing restore the smooth shine?

==== Countertop Specialty comment:

It may not be the grout at all. It could be a "grout haze remover" or similar product that was used on the backsplash to clean up after grouting. Possibly it was also used to wipe off the countertop damaging the polish or resin of the quartz.

Repolishing quartz can be done, but it's not common. You'll want a person experience with quartz countertops. Although, repolishing may not solve any discoloration of the resin.

Solution for Quartz Countertop Etching with Limeaway?
by: Anonymous

This may seem idiotic, but our Quartz countertop was so extensively damaged ( etched dull big spots) that I am considering covering the remainder of the surface with the same product to at least have a uniform surface appearance. Please advise. Thank you!!

==== Countertop Specialty comment:

Well, in theory, the idea isn't bad since you probably cannot repair the etch-like damage.

The only problem is that it will be difficult to control how the Limeaway reacts over the entire surface. You may get fairly even color, but it could be somewhat splotchy as well.

Although, even if it does turn out splotchy, it may look better than one big etch mark.

Quartz countertop damaged by Bostik grout?
by: Anonymous

My quartz countertop was installed 10 days ago. Today, my backsplash was installed by installers and home improvement store suggested they use Bostik grout. Many areas of the counter look like the polish has been removed. Is there any way to restore my countertop?

======= Countertop Specialty comment:

It may be possible to restore the shine to the quartz countertop, however, it must first be determined what happened and why.

I suggest contacting both Bostik and the quartz countertop manufacturer.

From Bostik you want to know the composition of the grout, chemical ingredients, etc.

Then from the quartz maker you want to know if anything in the grout would damage.

You may be able to have the surface repolished, but be sure to use an experience pro. Also, speak to manufacturer for specifics.

And you may try using Bar-Keepers Friend and/or a "magic eraser". Both have been successful at times removing weird spots from quartz countertops.

quartzite (natural stone) etching
by: Anonymous


Maybe you can shed light on a debate about what is etching quartzite (the natural stone, not engineered). On one side of the debate are those that believe it is because the stone is not "true quartzite" because true quartzite is highly resistant to etching. What that side does not take into consideration though, is that the majority of slab products have a resin applied at the quarry before shipping (to prevent fractures, enhance color, etc.).

The other side of the debate believes etching is caused by a chemical reaction between the resin (not stone) and acid.

The last explanation seems to make the most sense because people with the same material are having different experiences with etching, where some etch and others do not. The second camp said it's because resins can have different ingredients depending on the country the stone was quarried/resined.

Appreciate your thoughts.

=== Comment: Well the debate will continue because either side could be right in any particular case.

Quartzite won't etch... some resins will and given that many/most are resined it's most likely these stones that experience the majority of etching problems.

However, it's possible to get mixed stones that don't behave like the traditional stone in that geological classification. Thus, it is possible that some stones labeled as "quartzite" could etch.

But these will be few... resins are most likely cause.
