I have a chest-on-chest project about half done (the casework is mostly done; need to do drawers yet), and managed to spill a wipe-on-poly finish on the side of the upper case before I've put any finish on it. The spill was for another project I was working on in parallel (a book case for SWMBO); that will teach me to try to do two things at the same time.
The sides of the cases are cherry plywood, with a cherry face frame. I tried to soak a rag in mineral spirits and wipe it off; looks like I got most of it, but you can still tell where it spilled.
I will be sanding it, and right now the plan is to finish it with Watco's Natural followed by a shellac topcoat. Should I try to do any more with cleaning it with mineral spirits (or something else), or just hope it comes off with sanding?
