Rit Fast Fade is a concentrated prewash to fade and soften jeans and denim. Use in the washer with the hottest water available and agitate for 40 minutes (this will require a reset to the wash cycle before the water empties). Then just run through another full regular cycle. Can be tumbled or line dried. For a light fade, use 3-1/2 scoops per washer load. For a heavy fade, use 7 scoops per washer load. Repeat process if more fade is desired. Contains Sodium dichloroisocyanurate, Sodium Carbonate. Keep out of reach of children.
