I only used it once for majorly set in stains- formula yellowed spots on hand me down baby clothes. I soaked everything in water and oxi clean overnight, then put everything soaking wet into the washing machine a washed with a free and clear detergent on cold. It took all the set in stains out on the first try. Someone posted some links on here a few months ago when I posted about the stains.
