I have a stainless boiler which unfortunately got completely forgotten about after the last brewday.
It sat for over a month with the dregs of wort and hops in the bottom.
Well when I came to just check it, the fact I had left it out for cleaning later that day and forgotten it never crossed my mind.
Well there was something living in it. Luckily most of it poured off but I am left with mold all over, stuck all to my pigtail element, and also all inside the copper drain pipe underneath.
That copper pipe being the problem as I cant use any of th chemicals I use at work as they are for stainless only.
Any ideas how to save this, as I'm at a stage where I could just throw it away, although I would hate to!
