Remove the cleaning solution and rinse the costume thoroughly with cold water. Be careful not to twist or wring delicate fabrics. Use a towel to soak up excess water.
If your costume is machine washable (check the label or manufacturer's website), skip the rinse step and place your item in the washer. Select a low-spin or delicates cycle, cool water and a gentle detergent. For an extra boost to your detergent, add a scoop of OxiClean™ Versatile Stain Remover to your washing machine drum before adding clothes.
