Spare air

JD:
I have a large propane cylinder which has stood outside open to the elements for a few years. I want to add this tank to my air system for extra storage. I have all the fittings I need to use the original top valve. I can also get the cylinder hydraulic tested.
What is the best way to clean out the inside of the tank to make it gas free.

Remove the top valve, add some water and swish it around empty. Rinse and repeat until satisfied,dry out and then replace top valve and go for it.

Pete.:
I wouldn't even bother with drying it out, it'll get water in it as soon as you start pumping it full of air.

To that end I would mount it on the wall upside down and fit a drain loop on the inlet.
David Jupp:
Getting cylinder hydro-tested would also empty, rinse, and dry it...
JD:
Gentlemen thanks for the quick reply.
Pete, drain loop that should help keep moisture down.
David,Pete49 water seems to be the way to go thanks.
