Ok, I've been wanting to post this thread for ages.

I modified my usual routine years ago and stopped wearing perfume on my wrist, with the assumption that at some point in the day my hands will end up in the tank. I also suffer from dry, wintry hands because I will only put hand lotion / body lotion, etc. on at night before bed so that I can wash it off in the morning.

I'm a bit of an OCD hand washer anyway and then do extra rinsing to make sure there's nothing on my hands for the next time I go into the tank. I once heard / read a story about a woman killing her fish because she still had a bit of soap on her hands after washing them. I worry about all kinds of things harming my water, corals, fish. Like deodorant (since it is not too uncommon for me to reach way down in the tank and be in up to my armpit).

So... am I the only one making all these accomodations? Is it even necessary? What do we actually need to worry about being on our hands and getting into the tank? I'd love to hear others' input.
