Wash the upholstery with a "W" or "WS" with a water-based cleaner. One-part dishwashing liquid with 2 parts lukewarm water is suitable for cleaning surface stains on the upholstery. Squeeze out excess moisture prior to wiping down the upholstery to avoid soaking it.
Spray a solvent-based cleaner on the upholstery for "S" or "WS" letter on the cleaning tag. Solvent-based cleaners specifically for upholstery are common in the cleaning section of your grocery store, and they use chemicals to lift stains from the fabric. Follow the specific cleaner's directions carefully to prevent damage, as many cleaners suggest light misting over stain saturation.
Call a professional if you see an "X" on the label. A professional upholstery cleaner inspects the severity of the stain and uses a steamer to extract spots.
