I know you all know your woods, so I figured I'd ask here ... Hope that's cool I bought a used desk -- total steal for what it is, but it wasn't exactly been well cared for by the original owner. The surface has a bunch of stuff on it that didn't clean off with mild soap, water, and elbow grease. No idea what all is on there beyond some obvious water stains and small scratches. The manufacturer says the desktop itself is finished in wood veneer. It's kind of a semi-gloss finish, very smooth to the touch. If I can't easily clean/restore it, no big deal. But I'd like to try - without totally ruining it Any ideas? Thanks!
