Cleaning Your Fire Helmet
Your fire helmet needs to be cleaned often. Simply use mild soap and lukewarm water to remove most dirt and some smoke residue. Rinse your fire helmet with lukewarm water after using any cleaning agent. Be sure to disassemble your fire helmet according to the instruction manual provided with your helmet. Some cleaning agents contain chemical solvents that attack thermoplastic helmets. Solvents can destroy the helmet, especially when applied to stressed areas such as key slots, faceshield mounting brackets or rear brim D-ring.
Never use 1,1,1,-trichloromethane, other aromatic/chlorinated hydrocarbons or brake fluid to clean helmets. These common chemical solvents attack the shell material and lessen the helmet’s durability.
