Most likely, I use a plastic ice-cream container to do my etching in as my
boards are usually small. Fingers I find don't fall off when inserted in the
FC, I may go out on a limb here but I'm sure it would take a while to feel
any effect from leaving any FC on your skin for a while. Water cleans up OK.

BTW, if you go down this road with the Press-n-Peel, I think a laser printer
is the go.

Cheers.
