Rusty HP steel 100, brushing the interior

This is a follow up from a previous video, which had lots of interior rust.
I brush out as much as possible and see the results.

Thank you for sharing the "inner workings" of your shop. I love watching how things get done and seeing what's "behind the curtain." I learn a lot more with each video.

[@scubatechkeylargo]

I glad to hear you learn new stuff, that's awesome. I'll be posting lots more, thanks for watching!

I'm from Pakistan And work as a tester, believe me your videos teachs me toooo much information about cylinders. I love your channel 💞 and always wait for your new videos

[@scubatechkeylargo]

Heading to UK from Spain to train and certify in visual tank inspections. Just been playing with an endoscope camera ... wasn't as easy as I thought to actually see the interior so maybe a mirror is better after all. great top see yoru idea on the internal devices to clean off small specks of rust. thanks for sharing your video

[@scubatechkeylargo]

I hope my videos help you in your tank inspections. Good luck with your training.

Very interesting and informal, would you do one on tank o2 cleaning? that would be fantastic

[@scubatechkeylargo]

Next O2 cleaning customer request I'll make a video. Thanks for watching.

[@oskarchen981]

great video. thank you. quick question regarding the brushed tank, do you think the VIP of the tank will fit oxygen clean criteria at this point? or you would have tumbled it (and O2 clean)

[@scubatechkeylargo]

No, a light tumble with O2 safe cleaner is needed.

What do you use for tumbling media? I've used stainless pins, corn cob, or walnut shells on ammo brass. I'm curious what's used on scuba tanks. Great videos, by the way!

[@scubatechkeylargo]

Steel tanks I use aluminum oxide chips which are jagged and hard. Aluminum tanks I have ceramic pellets and glass beads. The important thing to remember is that whatever media you use it must be able to fall out of the tanks easily.

Vinegar makes a great rust remover -- non toxic and harmless. And, it will process the bottom, sides, and neck to its level of fill.

[@scubatechkeylargo]

You're right vinegar works good on rust and corrosion but the negative is, I would have to wash out the smell with lots of water which leads back to flash rusting. In this case it's not the best choice.

[@crowdfundcrew]

With the amount of rust on that one I would have tumbled it - it would be shiny after a good tumble. I generally only use the whip when it's just flash rust - but of course it's my own tumbler and my own tanks and I'm not charging by the hour for the work 😁 - Steel tanks are nice that you can tumble them really well without hurting them. Hope the owner has that tank for many diving years. Donate for a Dream

What is used as rust inhibitor?
