We wish we could guarantee that our curtains will stay sparkly clean and white all of the time, but with normal day to day use, your curtains will get dirty. Shady Lane Curtains recommends keeping your curtains rolled up as much as possible to limit dirt accumulation.
Your curtains should be washed annually to restore them. Use water and a mild detergent to soak the curtain. DO NOT USE clorox, bleach or harsh cleaners. Wait about an hour and use a brush or rag to loosen dirt. Rinse curtain within 30 minutes and let dry. If using a pressure washer, do not spray directly at curtain and avoid spinner nozzles.
Never use a pressure washer on curtain windows.
