Default Cornelius Keg Stains

I have a couple of 10g kegs that have some very stubborn stains on the inside. I've used oxyclean, ecolox, scrubbed with hot soapy water, but nothing works. It's sort of a hard gummy substance that just won't let go.

Any ideas? Suggestions?

Thanks.

So it's actually a surface gum or is it actually the stainless?

Tough call. It's a hard brown substance that I think is on top of the stainless steel. I initially thought it might be rust or corrosion, but I think it's something stuck to the stainless steel surface.

Try Bar Keepers Friend. Thick paste and let it set for a while. It's Oxalic acid.

There is also PBW. Best to avoid any of the really nasty acids if you can.

If BKF can't move it, try some Goof-Off.
