How to Remove Existing Wood Stain to Refinish

Cover the ground of your work area with some scrap pieces of cardboard. Try to work outside if possible because the paint and varnish remover you will has very potent fumes. Place the piece of furniture on the cardboard.

Put on long pants, a long-sleeved shirt, an apron and safety glasses. You want to avoid getting the paint remover on yourself if at all possible.

Pour about half a can of paint/varnish remover into an old metal coffee can. Use a paint/varnish remover that contains methylene chloride. Methylene chloride is a thick chemical, and makes it easier to cover the furniture with a thick coating.

Dip a paintbrush into the methylene chloride stripper, and slather a coat of it over one side of the furniture. Do the top first, then bottom, so you don't have to move the furniture around as much while it is wet.

Allow the paint/varnish remover to sit for 10 to 15 minutes. You should notice old wood finish start to bubble and wrinkle.

Begin removing the finish by gently scraping it away with a scraper or putty knife. Remove as much as you can with the putty knife; use a stiff-bristled cleaning brush in the corners. Try to use a brush with plastic bristles or natural bristles because these are less likely to scratch the wood. Wipe away excess residue with a heavy duty paper towel.

Pour lacquer thinner into another metal coffee can. Dip a clean paintbrush into the lacquer thinner. Wipe the lacquer thinner on any remaining wood finish and chunks of varnish remover residue. Use heavy duty paper towels to wipe away the residue. Allow the lacquer thinner to dry and then do the other side of the furniture.
