Dear Home-Ec 101:
I have Corian counter tops and sink. The sink is stained because my family never cleans it. I try to clean it, but even with a special Corian cleaner or bleach, I cannot get the stains out after several cleanings.
The counter tops are clean, but dull. I tried a counter top polish and it did nothing. What am I doing wrong?
My sink is similar to Corian and frankly, I’d rather have stainless steel. I feel your pain. My sink, like all Corian sinks has a matte finish, which means it is safe to use a mildly abrasive cleaner. As I’ve mentioned before, my favorite is Bar Keepers Friend.
I apply it to the stains and rub gently, but not in a circular motion (their rules, not mine). On occasion I have to use good, old-fashioned elbow grease.
To help keep my sink looking nice and temporarily avoid new stains I wax it on occasion. Yes, that’s right, Carnauba Wax, it’s food grade.
As far as your counters go, DuPont says you can use a mild abrasive to remove stains and restore the finish. I have laminate counters, but if I were trying to restore shine to what is supposed to be a semi-gloss, or glossy finish, I might try Pledge or waxing, in a hidden area. If you choose to use Pledge, occasionally remove the build-up with mineral spirits.
