Chlorine bleach is your friend. It eats
diesel and
shower grunge and makes
women return. Spray it everywhere the
diesel may have seeped, but not on bare
wood. Let is soak a day. Let it sit in the
bilge a while. Maybe at 50:1 dilution.
Disconnect that
shower. That is a terrible idea. Never never do that. Even a dedicated sump is a poor idea unless you have a
cleaning crew visit daily.
