Phosphoric Acid for rust cleaning / inhibitor: Mixture and Procedure

[tmassey]

Because, according to my training in O2-cleaning tanks, the oxygen-cleaning process was supposed to be the very last step.

You are correct: the O2 cleaning *process* is supposed to be the very last step. Detergent by itself does not equal o2-clean. Nor does O2-clean equal a single step. And the detergent step is never the last step: you have at least rinse and dry. So nothing that anyone described violates that principle at all.

Chill, bro.

Thanks, I’m good. Bro.

I’m trying to avoid going the tumbler route at home. I think I'm gonna give this method a try. You just slosh some cleaning solution around in the tank and then do the same with the phosphoric acid solution?

For both the simple green and acid steps (when I use acid) I use my tumbler just no or very little ceramic media. You dont want the acid used up reacting with only part of the tank walls. All my tanks are pretty pristine inside though. So I only use media in extremis or if I get a new-to-me tank that needs extra love inside due to past abuse. I have acid washed (rarely) some of my tanks that ended up with a spot or two of rust on the bottom from a water droplet that wasn't blown out of the valve.

What's this tumbling isn't that what circus performers do, I call it rumbling but we don't talk about rumbling

Do youse blow like it blows you over as you're hooked directly to a tank without regulator so you really blow
