Look for the cleaning code marked somewhere on the couch to determine how to safely clean the fabric.
Identify the stain. The type of stain, along with the cleaning code, dictates the cleaning product that should be used.
Add 1 tsp. of mild, alkali-free liquid detergent to 1 cup of lukewarm water, if the upholstery is coded “W” or "W-S" for the first wash, if the stain is blood, chocolate, glue, egg, ice cream, juice, fruit, milk, tea, coffee or soda.
Add 1 tbsp. of ammonia to 1/2 cup water for the second wash if the upholstery is coded “W” or "W-S" and the stain is beer, blood, chocolate, glue, egg, ice cream or milk. Mix 1 part white distilled vinegar to 2 parts water for the second wash if the upholstery is beer, juice, fruit, tea, coffee or soda.
Moisten a cloth with the first cleaning solution. If the stain is butter, gum or lotion, use the dry cleaning solvent instead.
Blot the stain with the appropriate first cleaning solution.
Blot the stain with the appropriate second cleaning solution. If using the dry clean solution, use the soap solution as the second wash.
Sponge the stain with clean water if coded "W " or "W-S" to remove the cleaners.
