RIT ProLine Fast Fade is a concentrated prewash that fades and softens jeans and denim for a worn-in look. Use in the washer with the hottest water and agitate for 40 minutes (reset the cycle before it drains), then run a full regular cycle to rinse. Use about 3½ scoops for a light fade or 7 scoops for a heavy fade and repeat if needed; tumble or line dry after washing. Follow garment care instructions after dyeing for best results.
