Do I understand correctly that not all tanks are suitable for O2 clean?
So pricewise if I fancy to get Nitrox all I need for partial fills is clean tank and valve. Pricewise:
O2 cleaning for tank = $20 (at least in LA)
O2 cleaning of valve = ?
One thing, I don't quite get is depresurizing cylinder and letting regular air in. That will sure bring many hydrocarbons inside (as they are in regular air). Is it simply not enough to bother?
Thanks Roakey.
