Add Sun® to washer before laundry. See garment-care label or hangtag for washing instructions. Follow manufacturer's instructions regarding the care of all washable fabrics. Some fabrics may change color during laundering due to color variants in fabrics. Be sure to test for colorfastness before laundering. Colorfastness test: Dip a hidden corner of fabric in detergent and hot water. Rinse and let dry. Proceed if color is unchanged. Pretreat: Use for a few small spots. For best results, pretreat with detergent as soon as stain occurs. Rinse the stained area, apply a paste of detergent and water. Rub gently, and wash as usual.
