To remove enamel from mahogany panels, take a bucketful of freshly made limewash and add 2 lb. of common washing soda. Apply to the panels with an old brush. Several applications may be necessary. As the enamel softens, scrape off with a wedge-shaped piece of wood. Swill off with plenty of clean water. Should this treatment turn the panels darker in tone than desired, the colour may be restored again by wiping over with oxal'e acid, 1/2 oz. to 1 pt. of water. Swill off again with clean water, then wipe over with common vinegar to remove any trace of acid.
