phosphoric acid

Post by CaptnJack » Mon Apr 25, 2016 8:14 am

Does anyone know a source for quart or gallon sizes of phosphoric acid? I have some steel 72s and skinny neck 100s that I want to O2 clean and get the remnant rust out of. Yes I have a tumbler but the bottoms are especially hard to get rust free. I have used naval jelly intermittently in the past, but its not cheap and the jelly bits actually dilute the active ingredient more than I'd like.

It is available via amazon, I was hoping for someplace local though...

Hmmm wonder what else is in the kleanstrip? As in something non-O2 compatible?

Got nervous about other ingredients in the kleanstrip and Lynnwood is sucktastic to drive to. So I ended up ordering a gallon on Amazon for $37. It's 85% acid too so should only take a small amount.

Diet Coke
I've successfully used a solution of Diet Coke and white vinegar to remove stubborn corrosion from small parts. Let soak for an hour or two, no more. Not 100% sure about the application for O2 cleaning the inside of a tank, but using Simple Green afterward would remove all residue.

While I could try the diet coke route I really don't want to tumble them twice. Once is pain enough.

Oh those skinny necks are no fun to tumble

There's always Ospho which isn't that uncommon at hardware and paint stores.

And that coating is 100% O2 safe? Maybe its the same as the global rust inhibitor but I don't honestly know?

I believe the reaction converts ferrous-oxide to iron-phosphate but can't vouch for the other ingredients.

I already ordered some pure acid on amazon, the other ingredients scare me with pure o2 around. And washing 2x means re-rusting.

85% is wicked strong even diluted down to about 50%. Just for comparison, does anyone know the concentration in navel jelly?
