Rust Removal

[Mark]

I thought some here may find this interesting. The recipe is simply white vinegar and salt. This person used 1 cup salt to 1 gallon vinegar but apparently you get the same result with as little as a tablespoon of salt per gallon. I wouldn't soak a gun in it but plenty of other things to clean.

what do you know?

I wonder just how many years it is that I`ve known that acid will remove rust ?
See, Naga, being stuck out there in the back of beyond the world just passes you by.

This is very interesting.

Wow, wow,wow ! That might be a simple and effective solution to a difficult problem, and I never knew it. Thank you, Mark.

> Actually its simple chemistry....
> Salt is Sodium Chloride
> Vinegar is Acetic Acid (which is edible & used in cooking for marinating meat / flavoring etc)
> When these 2 are mixed a chemical reation takes place....
> The hydrogen ions in Vinegar (Acetic Acid) & Chloride ion from Salt (Sodium Chloride) combine to form "Hydrochloric Acid'
> Now 'Rust' is Ferrous Oxide (When Iron is exposed to Oxygen ie. Air - Rusting takes place)
> So when Ferrous Oxide reacts with Hydrochlorice Acid it becomes Ferric Chloride which is water soluble.
> Hence any rusted item when treated with a mixture of salt & vinegar & later washed with water removes the rust!!!

Dilute Hydrochloric Acid / Dilute Hydrofloric acid will give same result.

Thanks, Mark!

Goodbye, Rustoleum and WD40 and sandpaper............

I'm not sure if its safe for guns tough

[skeetshot]

Good find, Mark

It creates Hydrochloric acid (NaCl + CH3COOH)

That eats rust, Zinc etc

Definitely not! Remember the blue finish on guns is also a version of rust, so anything that chemically removes rust will also remove bluing.

Mark,
I don't have words to thank you. No post on IFG has timed itself as perfectly for me as this one

Please watch this space guys. Having banged my head and soiled a white Tee this morning, I feel RELIEVED.
