Any tips on cleaning a tank?

@flymolo He did not mention any cleaning agent, and I did mention the other cleaner guy I talked to uses blue gold. Also, my guess is they did use glass beads. He mentioned them having separate media for steel tanks and aluminum tanks. The abrasive ceramic bit was my assumption, not something he said.

@Endler's ...looks like the whole Jeesh is here. But also, I don't know anything about that that you have in your picture, but I'm scared to just put a cleaning product in there that might either react with the aluminum or leave a harmful residue for me to breath in. I have considered filling the bottom of the tank with isopropyl alcohol and water, letting it sit a while, and then rinsing thoroughly, but I don't know.

@Capt Jim Wyatt Will that remove the residue when tumbling it did not? And is it safe to use on a tank? I'm worried about leaving a residue that I then breath in.

Simple Green is a soap frequently used to clean and remove hydrocarbons from tanks for use with high concentrations of oxygen. It leaves no residue with a rinse of a good amount of water. Rinse until you no longer see a film on the surface of the rinse water after draining. Use distilled water for the last rinse if your water is not pure.

Blue Gold is a similar cleaner.

I'll take that under advisement.

So how is the advisement coming along, they tell me The Pope is a bit crook at the moment
Has anyone admitted or whispered in your ear that if you stain an ally through your method

You will live with it forever and a day as once it gets in, through in to the grain it is in forever

unless you fix it like this

or rinse it out, put the valve back with No lube on the threads and go diving

It might be worth going back to the place that fills your cylinders and seeing what is coming out of their compressor. Put a white cloth over the fill whip and let it run for a while. If they are pumping crud out then they need to fix their system before they contaminate more cylinders. And based on what you see on the cloth you may be able to determine what’s in your cylinders. You said they don’t require VIPs. I would be worried they are cutting other corners and not maintaining proper maintenance and filtration.

@Tim Clark Diving I worry the same thing. Of the three places I got fills at between when I last looked in the tank and when I found water in it, two were not in my local area, and places I will rarely if ever get fills at in the future so if it's one of those, I'm not worried. My local guy, him I'm worried about, particularly since despite having a very fancy compressor, I just don't the vibe he really knows what he's doing all that well. My solution is I'm going to periodically check my tanks (on a rotating basis, to diminish wear on any one tank from screwing/unscrewing the valve) and definitely check them before I get them filled somewhere else. If I find water in a tank that's only been filled by him, we're going to have a chat. Till then, not really worth worrying about, besides the basic level of "does this smell funny? Do I feel lightheaded? Do I have a headache?"

I need to buy a gas analyzer that does CO2 and CO, tbh.
