I wouldn't worry about it one way or the other. If you are super
worried, remove the automatic bleeder on the bottom of the tank
and install a ball valve or similar. Pressure the tank until the
regulator on the compressor is happy. Close off the compressor.
Open that bottom ball valve and blow down. If you are worried
about mold, mildew, unknown bugs, etc., make up some bleach
water - about 5 water to 1 bleach, empty the tank, pour in a
gallon of the mixture, shake vigorously (yes, I'm kidding), and
pressurize and blow down.

I can't imagine anything in the tank being unsafe. You will be
compressing your own "dirty air", I doubt that the steel tank is
holding much in the way of residual nasties.


I suppose NONE of you guys ever used a device for other than
its intended use.
Just cause it says it's an air tank has no bearing on what
might have been stored in it. And the external environment
matters. Maybe it was used at a nuclear waste recovery facility.
Or an anthrax decontamination project.

I've got milk jugs full of used oil. Would you buy a used
milk carton and put milk in it? What I told you about it
is irrelevant. People LIE!!!

Use your head.
NEVER assume anything...especially if it's on ebay.
