I own multiple aluminum tanks and one steel tank and only permit refilling no exchanges.
A coworker a few years ago took the steel tank for refilling and came back with an exchanged steel tank which gave me problems. Very small particles came out of the tank. Now all my tanks have filters and after a few years don't look great.
I have know idea how clean my own tanks left the factory.
Corrosion can and will happen inside tanks.
Never leave an empty tank open for moisture to enter.
My tanks are filled by Airgas directly.
Look closely at the old picture and you see how the filters look after around 2 years of service with alot of CO2 use.
