Never use paint remover or strong chemicals to dissolve paint. They may cause extensive damage to the finish. Wipe off water-thinned paints with wet cloth. Wipe surface immediately with dry cloth to prevent water damage to finish. Caution: water will make shellac finish sticky.
Remove fresh oil-base paint by rubbing the spot with a cloth saturated in liquid solvent-base wax.
For paint stains that have dried, cover the spot with boiled linseed oil. Let stand until softened; then remove with a cloth dampened with boiled linseed oil. If any paint remains, remove with rottenstone and oil, using the same procedure as prescribed for alcohol stains; or gently scrape off paint with stiff cardboard, a plastic bowl scraper, or a fingernail.
