1 Answer


For minor buildup and staining, there are scouring and polishing compounds and sticks - check with your local countertop store for these - though requires you to know whether your sink is pure resin, resin composite, quartz compounded, epoxy quartz, or whatever - there are about a half dozen different compositions and binders. Ditto for the sealer you need after you have cleaned it up.

If at all significant buildup, takes a LOT of elbow grease - contractor would use primarily an angle grinder with polishing discs and pads on it to work through several different compounds to restore it, smooth it, then polish it - then would reseal it also.

Otherwise, professional Countertops would be your Search the List category for a contractor to do this.
