I've heard it's ok to shower lightly (no scrubbing or exfoliating) 2 hours after application. I have a wife and small children, and I would only apply on areas that I could cover with a t-shirt - chest, stomach, shoulders, sometimes thighs. The biggest hassle was that I had to sleep in a t-shirt, which I hate, but I didn't want to smear the sheets with PH. One thing I like about 1-test transdermals is that the 1-test burns on contact, so it actually acts as a warning upon contamination. I've never had a problem, I just kept covered up. Also, make sure you use latex gloves - easier to prevent contamination, and you're not scrubbing for 15 minutes!
