Use Jasco premium paint and epoxy remover for wood, metal, concrete and masonry. Strips multiple layers in 15 minutes. Directions for use: Shake well. Pour into a metal container and apply a thick coat with a paint brush to a small area (up to 3 ft. x 3 ft.). Brush in one direction only. Leave the area and let the stripper do the work. After 15 minutes, test scrape a small area to see if varnish is ready for removal. Remove loosened varnish by gently scraping in direction of wood grain with a plastic stripping tool. A toothbrush, toothpick or stripping brush will help remove old varnish buried in recesses. Multiple coats or stubborn varnishes may require repeat application. Use a clean abrasive pad dipped in after wash or mineral spirits to loosen remaining varnish and remove any residue.
