Muriatic acid is another name for hydrochloric acid, and it is the acid that's in your stomach. It's one of the reasons that we need salt. The chloride ion that occurs when NaCl is dissolved in water is what the body uses to make the acid.

Does that mean we can swallow small parts and bolts and clean them?

I've been playing around with diluted Citric acid recently which works very nicely aswell to derust metals.
If you're not in a hurry it will derust rusty metal in a couple of days.
Does the citric acid dissolve all the oils, grease, and heavy rust?

Vinegar is acetic acid, I don't think it'll neutralize muriatic. Baking soda will.
Im still confused about the neutralize part.. How do you neutralize? Do I mix the baking soda with the Muriatic Acide? or do I mix baking soda with water to dip the part in right after the acid bath?

Have the baking soda bath ready for the parts, the minute you take the parts out of the acid.
If you try to neutralize the acid directly you will require a lot more soda and have to buy new acid for the next batch. But it could be done, just not cost effective and messy when the soda started to foam.
R.
But the real problem, as alluded to above, is that this is not a harmless way to remove rust. Acid does not stop with the rust, it keeps on going. Acid-dipping body parts was not done to derust them, but to thin them. It was a way to make a lightweight part, by "chemical milling" much of the metal off the part.

the real issue is, how do you get rid of the stuff when you are done?
That was my issue that I realized right after pouring it out.

When the acid gets really dirty and you want to dispose of it, just add backing soda to it until it stops fizzing. Then you can just dump it.
lol.
while it is no longer acidic. it is still not safe to just dump.
you should still have your local garbage hazmat take it away. like paint and batteries.

Muriatic acid is marketed as a pool cleaner. When it's used for that purpose it's jut left to evaporate or rinsed with water.
sure, just pure, or mixed with water.
but what kind of goop came off in it when it was used for stripping parts?
you can't call that safe.

I just put my e-body frame rail in my bath, i make forms to fit, been doing this for many years. I mix one gallon acid with 4 gal. vinegar and 4 gal. water. Cheaper this way but takes a little longer. Make sure you use a neutralizer to keep fron rusting back fast.
Do you mean your bathroom Bath-tub?
What ever container i make or use for my bath(mixture)
Yes neutrlize in seperate tank to get in all the cracks, i use washing soda.
USE outside!

Oh, another hit against muriatic acid. Years ago I heard a loud bang in the garage. Went out to see what happened and nothing was obvious, till I later tried to open the door. The helper spring on one side broke. Turns out m wife had stored the remains of a gallon of muriatic acid she was sing to maintain the pool and the plastic container allowed it to leak/fume. The vapors rusted the spring out till it broke. Rusted out the freezer next to it too.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

Need to be wary of what it is doing to the metal, and how much it is eating "the good stuff" away. I researched its use years ago when I was cleaning stuff for the Dart.
Guy over on BBD threw a set of rods in EvapORust (not sure what it is made of), but they had matching wrist pins (press in), he removed the rods, and the pins fell straight through the small end...
Disposal seems like it would be a PITA too. But to someones point above, once neutralized, is it really any different than the contents from a parts washer?

Iron, and the stuff you were going to scrape off anyways. Once neutralized, no big deal.
Maybe, although the neutralizing itself does little to remove potential heavy metal toxicity, and technically, its far from legal to dump or dispose of haphazardly of any of the waste product.
Virtually everything you stated is incorrect.
