You can wash some helmets internally with laundry detergent and water, rinse very thoroughly with a garden hose to get all the detergent residue out (it can get pretty funky too when it decomposes), and dry for several hours in front of a fan. However, in some, washing can undo the adhesive that holds the fabric liner to the shock absorbing foam. I don't know about Arai specifically.
For less severe cases, you may get decent results with Febreze Extra Strength. It's a household and automotive fabric deodorizer that consists basically of rubbing alcohol, modified corn starch for odor absorption, and a scenting agent. You'll want to air out the helmet VERY thoroughly after applying the stuff because that scent is pretty powerful.
