Way of saying 'washes hands of it' but implies physical?

Question

Looking for a non-crappy way of describing someone doing that washing hand motion you do to clear your hands of dust or dirt, but without saying 'washing hand motion'. I feel like there's a good way of describing it, a stock phrase of some kind, but I can't remember it. Tip of the tongue, and it's driving me mad.

Answer 1

brush your hands, shake off your hands, wipe your hands
