How do you remove stains caused by water repellent spray?

To remove stains caused by water repellent spray, start by gently blotting the stained area with a clean, dry cloth to absorb any excess product. Then, mix a mild detergent with warm water and use a soft cloth or sponge to dab the solution onto the stain. Rinse the area with clean water and blot dry. If the stain persists, consider using a specialized cleaner designed for the material affected.
