I bid on one and I'm just going to let it sit for 24 hours with oxi-clean in it, drain and re-fill with more oxi clean every day for a week. That should pretty much remove anything that might be in it. I figure I can primary 7 gallons in it and then pretty much fill my 6 gallon better bottle to the neck for secondary.
my goal then is to keg 5 gallons and bottle 1 gallon.
