Last year I upgraded my countertops to some absolutely beautiful mesquite butcherblock coated in my favorite finish - Waterlox. Cha-ching!$$
Waterlox is impervious to everything except ammonia, which softens it.
Oh, yeah, also Oxyclean. Last fall Nancy soaked a blouse in Oxyclean and set the bowl on the countertop. The ring left by the wet bowl lip looked like a burning hot egg skillet had been left there. I initially thought that is what it was, but none of our pans matched the size exactly.
Since Waterlox penetrates wood and does not sit on top like poly, I had to sand down into the wood to remove the ring and then refinish that whole section of countertop to match the gloss. I'm so glad you only have to scuff Waterlox before recoating.
Last night she did it again.
mmmm, that's disappointing. I hadn't even had my coffee yet. I'm pretty proud of myself for my restraint. The words left in my brain by my restraint are still searing my grey-matter.
Here's the section I get to refinish again:
