Muriatic Acid

Per my post of a week or so - this stuff works great. Yes, smells like he*l. A couple of more questions about it's use. Can I assume that it weakens as it is being used? It's been 43 years since I've had a chem. class but with the chlorine coming off, I guess after a while I would end up with water and iron in some form. Also, is is safe to use on brass?
Thanks for all the help guys. I'm working on a couple of pre-1898 pistols. Not worth a whole lot, but I'm really having fun with this project.

I'm Sure that muriatic is a deluted form of hydrocloric and it is not good to breathe it in. It is used in the masons trade a lot and will keep in a plastic jug for years.
You'v gota kill it to grill it

"Go to Lakedaemon, stranger passing by;

Hydrogen from the hydrogen ion penetrates the boundries or interstices of steels'crystaline structure causing hydrogen embrittlement.
The embrittlement can be reversed by baking after an acid treatment.
The temp and duration of the bake would have to be researched.
When you are done it does no harm to dispose the used muriatic down the drain. Flush it with lots of water. Water neutralizes it readily if you happen to get any of it on you. Wear rubber gloves and goggles, it is not as toxic as many acids to your skin but it will work on it.
It won't hurt brass in the least, but as stated it will stain it a little. Muriatic will clean and save a lot of brass valves and plumbing fixtures.
Now if you want to get radical with brass and copper you can clean it with Nitric acid. Nitric is a different much more dangerous to use acid. It will take off layers of brass and copper until it is gone. You can drop a copper penny in nitric acid and the smoke rolls until the penny is gone. Nitric will also eat proteins out of your skin and turn it bright yellow.

The spa stores won't endorse it since it is so cheap compared to the high priced granulated "pH Reducer" that they like to promote (and they also like to point out it's hazardous/dangerous nature). The expensive stuff is a hassle to use also. I just pour in a couple of 8 ounce shots of acid after a fill and I'm pretty much on the money for about $0.25 verses $10.00!
Also, it takes the glaze off of concrete nicely. I epoxy coated my garage floor (epoxy paint), but had to etch it first w/Muriatic Acid.
The paint store suggested a water/acid ratio of 8:1, but it was not productive. I went 50/50 and it really did the job! It stinks like H*** as someone said here, but w/good ventilation it wasn't too bad.

Takes the sting right out of the gas, but you still need oxygen.
Check any industrial supply for the respirator; there'll be info on correct filters.
3M 60922 Combination Cartridge/P100 filters for Acid Gases and Particulates on a half facepiece (6000 series) respirator do a nice job.
3-M has a great support line if the counter people aren't experts.
I get'em at Grainger, online, UPS'ed to the house.

Same thing with carbonation in plastic soda containers after awhile.
The polymeric chains in the container have a strong covalent (ion sharing) bond between their molecules, but the weaker secondary bond (van der waals bonding) between the adjacent chains is the "weak link" in the structure that allows gases to pass through in time.

Do this outside and stay upwind. Inhaled... can be toxic. This stuff really stinks!
For your safety: Go to Lowes or Home Depot; get a resperator designed for "acid gas"--it will cost you around $20. Pick up a decent pair of safety glasses or goggles (one designed to protect from "splashing") if you don't already have a pair.
Use your safety gear when working with the acid!
