Peggy - Holding tank was full and we didn't realize it. Head was operated and forced contents up the vent. Hose clamp at the thru hull vent fitting was loose, and we got bad stuff in the hanging locker. I used Simple Green for initial cleaning of the locker, and then took your suggestion to others to spray the interior with KO and let dry (did it today so don't know how successful it was.) Any other suggestions on the locker cleaning? Also, foul weather gear that was in the locker is now very foul smelling. Put it through a full was cycle in the washer with detergent, and hung outside to dry. Still has the smell, but not as bad. Any suggestions for how to clean up the gear? Have read your advice on several boards, and haven't seen the clothes cleaning issue addressed.
