I have processes for my entire kit (and bicycle) before and after each ride. I like to air dry/hang in the sun my sweaty items after each ride (even if the item is going into the laundry after it air/sun dries. My helmet I wash in a sink similar to the way I'd wash dirty dishes if it has any salt build-up. I also wear a do-rag which helps to limit some of the salt/mineral crap.

If weather conditions don't allow me to hang my gear on the deck to dry in the sun.... I hang them in a spare room with a ceiling fan. On occasion I've hung gear in the garage or laundry room with a box fan to dry them.

Having extras of everything... helmets and gloves included... is key to always having clean, dry, odor free gear. Gloves I use an old diaper pin to keep the pair together and just toss in the laundry from time to time.
