What to store phosphoric acid in.

What did it come in??? 
It should at least be in HDPE, or a poly lined metal container.

I always store it in the jug it comes in. If soaking a part, I use a steel pan.
Did you check it for leaks before?
Glass containers work well for acids.

Except for those that will eat through glass. I think Hydrofluoric and sulfuric, but high school Chemistry class was over half a century ago.
I don't think we're talking about those, though.
Batteries used to be made out of glass. I believe that is where the tale of sitting batteries on concrete will discharge them. It was more like break them. Just my opinion.
200 years ago, then batteries were made out of of wood.. and were that tale came from.
Batteries used to be made of clay.. and where the tale came from. 
It was in jugs that appeared to be plastic. I poured several jugs in a large storage container and added some water to get some fairly large pieces in. That container eventually leaked and I put what was left in the five gallon bucket. I’ve ordered an HPDE bucket with lid for my next batch. Thanks for the advice. Only a couple of parts left for the car but I’ve been using it for tractor parts too. I really like what it did for my parts but it sure ruined some concrete!What did it come in???
No, but it had not leaked for a few weeks until now. Then it really came out.
I read on google that phosphoric acid can etch glass. Don’t know. I’m not ready to trust anything right now, LOL
Me and you both!

It's the concentration that does it. Phosphoric acid is what makes coca-cola sour.
Only HF etches glass. Whatever you have will be fine in any glass bottle.

And why would poison be in Coke? Kinda like TSP in cereal….
HDPE should work. A lot of pails and buckets are made out of polypropylene these days and it is not nearly as chemical resistant as HDPE.

It's an acid, not a poison.
So is citric acid, which occurs naturally in your body (remember the Krebs Cycle?).
Even actual poisons won't hurt you until you reach an actual dose threshold.
Tylenol is good for your headache, unless you take about 20 at once, then the fact that it is literally a poison becomes important, as it permanently damages the cells of your liver, causing liver failure and death.

I looked at the difference in all the “zero” soda that’s out. It’s become my favorite, even better than regular pop. You guessed it; more phosphoric acid than regular. And I wonder why I get heartburn. Duh
I suppose the concentration in the bucket was much greater than in the original large tote I had it in. It evaporated down and I moved it to the bucket. Still not as strong as it was in the original containers from the store. It was either evaporust or metal prep brand.
Thanks for all the replies. I think the HPDE that several of you mentioned will do the trick.

Yeah, it’s still toxic at the concentration levels found in coke. And when the levels in your body are too high, you’re “poisoned”….

LD50 is 2600mg/kg.
That's 2-1/2 times actually more H3PO4 than a creature weighs.
It also doesn't accumulate in the body.
Where are you getting your information?

Chinese bucket, the probably used AI &fl figured out what you were doing with it and made it crack
Yeah, but I got my buckets free when I bought something. It was worth what I paid for it. Had to pay something for a good made in USA one.
