There are two ways you can go about cleaning your curtains. You can either dry clean them or wash them in water on a gentle cycle. If you choose to dry clean them, make sure they are first hung up on a line outside and then taken to the cleaners for professional care.
If you’re washing them at home, use cold water with bleach added if available since hot water will cause the fabric of the curtain to shrink. Also, find out what is recommended by your washer manufacturer for detergent type and the amount needed per load size before loading into the machine.
