God help us and our super-stinky bilge

Can you make sure he's well scrubbed before the weekend?

In days gone by the cross channel ferries had problems with "unpleasantness" in heads and tanks, by-products of 'mal de mer', semi-solid chip fat and other matter. They used a product called Gamazyme which I believe is still available. It was squirted in to all the facilities and the active bacteria within populated the pipework and tanks then proceeded to eat their way through the grot until light and purity reigned. It was good stuff and even had a NATO stock number because the "Andrew" used it. It used to come in a box of 12 x 1 litre squeezy type bottles. There was a joke that each box came with 12 bottles and a mallet, because once the bugs had eaten all the grot they turned on each other until there was only one big bugger left. That's when you needed the mallet. There were times when it didn't work but on investigation it was shown that the dopey deckies were squirting Gamazyme down the loos with a bleach chaser, thus killing the bugs.

coo. that looks good too. Will get that too and see what works.

With a steel hull, you need to be careful what you put in it. If the cleaner affects the protective coating, which can be anything from bitumen to epoxy, you expose the steel to salt water. But you knew that of course. Not sure all those responding did.

The first thing is to get the hole completely empty, and that means access to make sure. Not what you want to hear of course.

Yes OP, please report back. I'm following this with keen interest.
