I'd iodine the beejeebers out of it. Squeeze and make it bleed if
possible
and then get it good and dry. Repeat the iodine a time or two
more. Then
be vigilant.
Iodine I don't have. Hydrogen peroxide I have. Something rattling
around in my brain about relative antiseptic values but I will have to
wait until I awake to figure it out.
