Help in Cleaning hoff stevens
I bought a bunch of hoff steven kegs that had been sitting unclean for around three years. I have a standard hoff stevens keg cleaning system and I have used several types of cleaning agents such as sodium hydroxide and pbw and there still is a brown film on the inner surface of the kegs. Could it be beer stone?
I washed my test kegs for an hour at high temp.(+165F) with sodium hydroxide and let them soak over night with the same solution. This morning I washed the kegs for an additional hour and still the same brown film. I attached a scouring pad to the end of a stick and scrubbed the surface with no result.
Any suggestions? I am dead in the water with tanks full of beer.
