WTB Tank Whip (For Cleaning)

[rjack321]

Can you re-use the mixture to do a second tank, or is it one and done?

Thanks for the link!

It's one and done usually.

Unless the (steel) tank is pitted or has flaky scaly rust and need major refurbishing there is no need to use media/tumble. And definitely no need to screw around with whips and then washing out the rust dust.

Phosphoric acid removes all rust, getting the concentration right is the only issue - more is not always better. Phosphoric acid is food grade (its in coke and pepsi), the same acid in "naval jelly" and there is no residue to worry over O2 wise. You still need to rinse it out in order to heat up the tank enough to be able to dry it.

About how long do you whip it?

As hard as possible? Until its done?

Ok, I'll find some phosphoric acid locally and give it a shot. My tanks are not "crusty" or even bad at all. It's just a slight amount of surface rust from hydro that I'd like to get out if I can... if not it's really not the end of the world. I know some of my other tanks have some surface rust and they're fine.

You might be able to find it at a janitorial supply place. The big box stores will have navel jelly (which is fine for stuff like QC6s) but not the concentrated form. Amazon is much easier and cheaper for me than driving around at 16 mpg in my pickup.

I just looked, home depot does not have it, Wal Mart does, but the same price as Amazon.... Amazon it is then.

Depends how bad it is. Usually a few minutes.

I will use the same solution for several cylinders, both for the tumbling and the more diluted mixture for the rust inhibitor if they come back from hydro at the same time. I don't think the solution would become exhausted that quickly.

Any idea on the length of those cables? Are you happy with it?

Any issues getting the hose clamp into skinny neck tanks?

I saw the thread on here about someone doing that, but would that fit into skinny neck tanks? He used JB Weld to attach the strand to the rod and some thin line wrapped around.

I believe it was @Eric Sedletzky , he might remember where to find the thread, as I can't.
