I was recently cleaning my kegs using my sump pump method. I fill 2 kegs with hot Oxi-Clean, add enough water in the bottom of a plastic bin that holds both kegs then pump into the liquid post of each keg, to the bottom and out the gas post and pressure relief valve.
A GREAT way to clean two kegs at once in about 20 minutes. Until...
This final time, I was sitting in the garage minding my business and about 15 minutes in, the pump stops. Hmmmm, thats odd. I turn around to check on it and I find this yellowish, oily residue has completely contaminated my water in the bin and both kegs, dip tubes, posts and pressure relief valves.
I remove everything and rinse well and sit aside. I can still after a few weeks smell this oily (machine oil I would guess) residue inside the kegs.
I just removed the lid, pressure relief valve, posts and poppets and have it soaking in hot PBW.
Not sure if I should try and salvage or not.
Does anyone have any cleaning methods or thoughts on if the hot PBW will take care of it?
Here's a couple of shots of the yellow mess. Also, what would be inside a submersible pump that would cause this? I have been using this pump for about 2 years.
