A Kind of Magic
Before this 'black magic' arrived, routesetters and their trusted apprentices would don waterproof clothing and powerwash all the holds taking many hours, lots of water and alot of scrubbing. Now, Percy drops them into the vat, leaves them for 5-10mins (checks UKB) and then places them in a different bucket to rinse. Easy.
