Quartz Countertop Stain
QUESTION:
I have a HanStone quartz counter top. Tea stains it. The manufacturer has told me to leave a soap/water solution to seep in and then clean it.
But I thought quartz is non porous and should not stain. Is there a sealer I should use for quartz? Some of the stains are not coming out. I bought quartz to avoid this very problem. Please advise?
ANSWER:
Well, makers of quartz countertops like to tout their product as "non-porous," but they all hedge and claim stain-
resistant and not stain-proof.
Straight from HanStone website:
HanStone™ is a non-porous material that is highly resistant to stain, scratches and heat. However, it is not stain, scratch, or heat proof. How they can legally get away with these contradictory statements is beyond me. It's unfortunate that they feel the need to be misleading, but they have to try to gain an edge somehow since granite has a long-established and better reputation.
You probably wish you knew this sooner, but there are some varieties of granite that are truly stain-proof. They are so dense that nothing gets absorbed, unless maybe a liquid was able to sit a few days without evaporating, which of course is near impossible.
If you are setting tea cup on the countertop and spills are staining, then the surface is obviously porous.
HanStone warns not to use any solvent on their quartz countertop. This may damage the resin and color pigments. Solvents are used all the time to clean granite and marble.
Because of this, I'm a bit hesitant on making a recommendation about what you should do to clean it.
Cleaning The StainTypically in this situation with marble or granite I'd suggest using a poultice.
In your case, I don't have too much confidence that it would have any effect.
SealingI would call HanStone and ask them if a sealer will damage the surface. I doubt it will, but I'm not certain.
If not, then yes I'd apply one of these
recommended marble & granite sealers. Follow the directions carefully and wipe the excess sealer off the surface before it dries.
Good Luck,
