[header] How to clean a nylon jacket [title] Apply mild detergent and water to food or drink stains. [step] Old or new food or drink stains can be removed by putting 3 drops of mild, bleach-free laundry detergent onto a clean cloth, and adding a few drops of water to the cloth. Apply the detergent solution to the stain on the nylon, and allow the solution to sit for 15 minutes. 
Using a different clean, wet cloth, wipe the detergent from the stain. Use a dry cloth to blot the remaining moisture from the spot.
