Chocolate contains cocoa’s dark tannins and cocoa butter’s oiliness. On washable items, remove the grease with undiluted laundry detergent dabbed on the stain, let sit 5 minutes and rinse with warm water. Now apply color-safe bleach to the remaining water-soluble tannin stains. We can help with washable and with dry-clean only items, our stain experts can get the chocolate out of almost everything.
