I was joking about the Lysol workout wear but the Hikari-Kaikaku Photocatalyst Spray actually coats any fabric with a germ-killing layer which will oxidize odors, pollen, and bacteria when exposed to light. Supposedly perfectly safe for the human body, which I'm sure just means it's okay to sit on a couch coated with the stuff, but a real OCD case (I'm not that bad, honestly) could try out a full body basting and feel more at ease in public. The coating lasts through 30 washings.
$69 at Compact-Impact.
