Since coffee is enjoyed while driving, walking and other activities, coffee stains on clothes are inevitable. To successfully remove coffee stains, it is best to treat them immediately. Pants that require dry cleaning only should be cleaned with specific materials to avoid ruining the fabric. It's generally easy to remove the coffee stain yourself, rather than having the pants dry cleaned.
Blot the coffee stain with a clean cloth to absorb the liquid from the pants. Occasionally, use a different clean section of the cloth to avoid spreading the stain back onto the pants.
Apply white vinegar onto a cotton ball, then blot the stain with the cotton ball. White vinegar is the best cleaning solution for dry clean only clothes because it contains natural acids that are safe on all varieties of fabrics.
Continue dabbing at the stain, replacing the soiled cotton balls with fresh cotton balls. Dampen a clean cloth with warm water and dab the water on the stain. The warm water will rinse the vinegar out of the fabric.
Lay the pants down flat and allow them to air dry. If you are wearing the pants, dab the wet area with a dry, clean cloth.
