Come on, Dan. Surely you are not so naive to believe that your tanks are 100% free of contaminants....ever. Besides, you're breaking the rules O2 cleaning your tanks without the cert to do it. :depressed:
Oh and that's "peace of mind," not "piece of mind." Piece of mind is what Phil got.

Most shops I have come across require annual cleaning of the tank and the valve. I also agree with Phil that ultraviolet light can not detect small enough amounts of contaminants. It is only good as a gauge in seeing that some exist not that none exist. $70 is high not to include VIP and a nitrox fill.
I clean my tanks and valves every year. It is not that hard and gives me piece of mind. I started doing this after witnessing enough "O2 cleaning" by a shop that sometimes never involved removing the valve only changing stickers. Oh and of course charging for it.
