Muriatic acid rust eliminator

[wristpin]

Thought id get a little sciency with muriatic acid so i have a rusty battery tray from the el camino.
One gallon of water to 50mL (2.5oz) gave 1.13pH. To low in my opinion. So i reduced it to one gallon to 1oz acid. That gave me a pH of 2.5. Me likey.
Ill post pics and time it takes to get to a stage. I will neutralize it with TSP (trisodiumphosphate). Both chemicals can be found at most hardeware stores and Walmart.

You need to watch out for embrittlement of your parts when soaking in acid.

I use Phosphoric acid myself. I buy "Prep-n-etch" found at home depot as concrete etch. Mix it 50/50 with water and you're good to go. Stuff last a very long time (do not put greasy parts in)

I recently discovered it's great for removing mill scale from steel parts. Very useful when tig welding.

I'd advise against putting very thin items in like tiny springs, etc as it will probably just eat them. Also, badly rusted thin items can come out with pin holes. Ashtrays are a bugger for that!

Its my neices '67 El Camino. Only parts i havent replaced are cab and doors. I could have sandblasted it but wanted to experiment. Ill get it powdercoated after its cleaned. I'll weld in any pin holes. Powder coat isnt affected by sulfuric acid so it wont every get shitted up again.
Phosphoric acid is good to use if there is zinc or brass based metal

You are correct. I haven't used it for brass but it removes the zinc from nuts/bolts etc quickly! That stuff is a no-no when welding!

The absolute best rust removal process is molasses and water!!! Sounds like a joke but it works beautiful.

 

[wristpin]

It does work. Pepsi works very well too. Need to neutralize and coat metal after any kind of rust abatement.

I made a tank and soaked my pick up cab in it for about two weeks... came out beautiful after power wash... works better in warm weather

Wow that had to be a big tank, how much did all that molasses cost you, Lol.

I made a big tank and filled it with whipped cream and soaked myself in it. It works best in warm weather too.

I think you can get molasses at the feed store at a fare price.

You know you are suppose to do that with someone of the opposite sex don't you. Kinda not the same thing by yourself on warm day. We may need to have a discussion on the finer things in life and how they work.
