Leaking beer cans

[KevinV]

In the fridge box which is all GRP. Galvanic reaction maybe

That's what I meant; a tiny bit of salt, a bit of moisture and the shelf, but even without the shelf you might get a differential between painted and unpainted parts? The metal is so thin, it doesn't take much (been there, used the t-shirt to clear up the smelly mess)

I think some of the cans are Al with a very thin layer of plastic coating inside them. I had a can of coca cola where there had been a pin hole in the coating and so the cola had eaten the Al and most of the ingredients had jetted out.

So that is my reason why I am just about to find an old can of beer to drink!
