We are in the process of finishing a cabin we purchased. Unfortunately the pine wood flooring is already installed. Since we are WAY down a private road (two track) we do not have electric yet. So while working there we are using a generator. We have done well placing plastic under it when we take it in from outside to store while we aren't there. But we recently had a roof and siding put on and the builder who did the work spilled gasoline from it on the unfinished pine flooring. And he walked in it. So I have several large spots in the bedroom and foot prints in the living room. Our plan is to eventually put a clear finish on it. Is there anything that will remove the gas stains on the bare wood?
