When I get to use my GGRN Special Bum Foot Cleaner and Deodorizer! In a plastic bag, mix one part shampoo, one part mouthwash, add an amp of bicarb, add warm water. Place patient's disgusting, crusty, stinky foot in bag and tape bag shut around ankle. Repeat with other foot. Marinate for a few minutes, agitate around feet, remove bag, and rinse!
Voila, CLEAN BUM FEET!
