Care Instructions
BRUSH ME, WASH ME: After each use, hose down your wellies. Once a month, clean off excess dirt with just water or water and mild soap. Use a soft bristle brush to scrub. Let them air dry naturally (avoid direct heat).
OIL ME: After drying, apply a rubber conditioner or natural oil to restore plasticizing agents in flex points (toe and ankle). We recommend using Revivex rubber care spray, available at grubswarehouse.com.
