SOS has mineral oil in it. That could be what damaged your counter top.
I’m just warning to wipe the bottle off carefully after use and don’t set it on Formica. Also, don’t splash Naval Jelly on Corian. Corian is tough as nails and easily resurfaced, but Naval Jelly will actually dissolve it. I think that it is the only substance that can harm Corian. The good news is that you can have it repaired and you won’t even know that your husband spiffing up the fireplace tools ate a hole in your counter top! Oooops. Did I let that slip?
