Hi @stray !
Actually, my countertop is not butcherblock wood! It's wood-like countertop, laminate I think. I can't find it on the ikea website right now, but if I remember correctly it's either the Ekbacken or the Saljan (I suspect it's the Saljan because I remember the ikea guy telling me it's the thicker laminate but the Ikea website doesn't show the wood-like Saljan countertops).
I'm also slightly wary of actual butcherblock wood for countertops because I didn't think I would be super neat and always keep my countertops dry and stuff, and I read on some websites that if you don't constantly oil it or maintain it the wood does get mouldy, depending on your luck, so I thought I'll go for wood-like laminate instead! We do wipe down the countertops often (more because I do food prep on it and it should be clean anyway) and when I put hot pans on the countertop I usually stick a trivet underneath it, so we haven't really tested it per se, but the countertop still looks like new 2.5 months on. It gets some oil splatter when I deep fry but a quick whiff with some dishwashing liquid on kitchen towels and a damp cloth wipe solves that quite easily. The only thing is that don't try and use the magic eraser on it, it seems to rub off some of the surface shine for some odd reason.
Sorry I didn't help much for the wooden countertop problem! >_<
