1. Dissolve. Test the paint on furniture with industrial alcohol. If the paint dissolves, it is indicated as shellac varnish; if the paint becomes soft but does not dissolve, it is indicated as a mixture of shellac varnish and natural paint. Next, test with natural paint thinner; if the paint dissolves, it is natural paint. 2. Brushing. Use an old brush or a disposable brush to apply the appropriate solvent to an area on the exterior of the furniture. Let the alcohol or thinner work for 5 to 10 seconds, then wipe it off with a coarse cloth or scouring wire. If the paint is easily wiped off, you can use alcohol or thinner to remove all of the paint, instead of using paint and varnish removers. The operation should be agile, the alcohol and thinner evaporate quickly. Wash a small area at a time, and change the cloth frequently to avoid rubbing the old paint on the furniture again. 3. Knife scraping. After wiping off the paint, go through all the furniture with a spatula to remove any paint residue. Furniture scrapers are the best, perhaps using scouring silk soaked in thinner. Scrape along the lines of the wood, being careful not to scratch the wood. If necessary, sand and lubricate the wood. Do not use force during the polishing process. After polishing, the furniture can be sealed, bleached, decolorized, or painted.
