Likewise, cleaning the helmet's interior brought forth another near-unanimous opinion: If the comfort liner is removable, wash it by hand with a gentle soap such as Woolite. Davy suggested using Johnson's Baby Shampoo. "It smells good, it's cheap, it's made to wash away hair and skin oils and dirt, and has the side benefit of 'No More Tears,' " he said. "You see, when you wash your liner you will probably never get all the soap out, and when sweat mixes with dish-soap residue and runs into your eyes on a hot ride, it stings bad!" Arai's Brian Weston said the key is thorough rinsing: "Rinse, rinse, rinse! Any soap residue may cause itching and burning of the scalp the next time you sweat in your helmet, so flush the soap residue out several times with clear running water. Allow to air dry; do not machine dry as liner materials will shrink and in some cases melt."
