@Dennis@beige.party those things are lethal. Hardly ever use ours (too much hassle to use and clean - prefer to just cut stuff normally) and when I do I still manage to nick, score or impale some part of a finger or palm most times. Even more dangerous during cleaning, in my experience. On a practical note - rub vegetable oil onto the white plastic to pull out the stain, then lots of washing liquid, rinse and repeat until clean. Works for orange carrot stain, at least ..
