I used KO, it is also an enzyme used for holding tanks
and head cleaning
. It works very well. I would squirt all down the leakage area, would take care of the leaked stuff. If you know where it is actively leaking, wet a rag with KO and stuff it around that area till you can repair.
I love bleach, ( what nurse doesnt
)Be sure to flush your bleach water really really well as it is bad for plumbing
and fittings, and especially bilge pumps.
Cheers, (sorry for you troubles)
