I wash the cylinders several times with as hot as possible water, and one last time with acetone (which evaporate in contact of the inner warm cylinder) and I blow the acetone damp out with hot air via a long steel pipe in the cylinder.
I live the cylinder for 24 hours in a dry place, than put 50 bars of air in (to be sure the last damp go out), I emty the cylinder and it's ready.

PS : don't put acetone in contact with the outside paint ...

Raph

If it works it works.

But...what grade of acetone do you use? If its not very pure there is always the chance that you may introduce more combustible contaminants that will stay once the solvent has evaporated...
