When my hands get stained from food handling such as peeling loads of carrots/beets I make sure to do lots of dishwashing by hand and finish up by scrubbing my nails and skin with a scrubby and brush. Cuticle remover helps to strip off a layer of dead skin, so that helps get rid of some of the stain along with it. Just rub on a generous amount and let it sit for a 1-3 minutes, then scrub off.
