I’ve removed several layers of paint and what I believe is shellac from 50 year old doors and trim. After stripper has fully dried I’ve sanded the wood surfaces, yet there is a gummy residue left on some areas of the wood surfaces. How do I remove this residue prior to refinishing? I’d like to shellac the wood to restore it to an original condition.
The residue is small clouded areas and appears to be in the pours of the wood.
