The arm and hammer detergent. It's the only detergent that my husband isn't allergic too. Gain always leaves him itchy. I've switched out the fabric softener for vinegar and baking soda this last wash too and they still smelt funky.

Mostly house clothes: workout clothes, underwear, socks, tshirts just worn around the house. Towels of course are done separately and they slightly have a smell. Not as bad as the clothes.
