Sometimes the best way to make a stain disappear is to add to it rather than removing it. We're not suggesting that you pour grape juice over a spaghetti-stained shirt; instead, cover stains with fabric cut into pretty shapes and attached with fusible webbing. Ask your child to choose the fabric she'd like; iron it to one side of the fusible webbing. Trace the shape she wants onto fusible-webbing side, and cut out. Remove paper backing, and iron the shape on top of the stain. Make several shapes to camouflage multiple stains or for a decorative effect.
I got a grass stain on brand new deck shoes. Using colored permanent markers, I transformed the stain into a picture of a meadow. Got carried away and put colorful designs all over both shoes. Everyone asked where I got the great shoes!
Or paint over the stain. My mother had a favorite demim skirt with a bleach stain. My sister painted a pretty pocket watch and chain that made it more special than when new.
