Help! Spilled mineral spirit-poly mix on my hardwood floor (with pictures)

Hi folks,

So Iíve done exactly one wood finishing project in my life, and one of the things I had left over was a mason jar containing a mix of mineral spirits and polyurethane. (This was the first few layers I used on the wood projectóa thisoldhouse article suggested I do so). Well, I just noticed that it tipped over and spilled on my hardwood floor upstairs. Probably spilled at least several days agoóIím guessing it ate through the seal on the mason jar lidóand left this 3D gelatinous mass on my hardwood. Itís shiny as anything but Iím guessing I should remove it. Also youíll see the gunk spread to a cheesecloth package nearby, so the whole front of that package (or at least its imprint) is stuck there too.

So should I get some pure mineral spirits and go to town? Or try scraping (has not been successful so far)?

any help greatly appreciated!

Mineral spirits won't do a thing. You will need to use a belt sander or multiple applications of a chemical stripper to get it off... or both.

Mineral spirits only works if the poly is still wet/tacky. Any solvent strong enough to remove the poly would also harm the existing finish along with having a too offensive odor to be inside the house. I agree with X, there isn't much of an option other than sanding/stripping and refinishing.
