Neutralizing Sodium Cloride in Antique Autos

There's a bunch of them out there, simply Google on Rust Sealant. I've used this with great results:

We use windex in the gun business to neutralize affects of corrosive ammo which produces the same salts .I believe the active ingredient is actually ammonia.

I would assume spraying down with windex or your own solution and rinsing would do it.

I'm not sure what the corrosive salt residue is on ammo, but can tell you that ammonia is very corrosive to brass cartridge cases. The British learned that the hard way in India.

The solution is sprayed down the barrel after firing it is recommended to wipe out or rinse with water .

You can have them chemically dipped if you're doing a restoration.....

Almost all corrosive salts found on vehicles are somewhat water soluable and that is why they corrode when exposed to water. Our approach on a current vehicle and what I will be doing once I decide on a product (I too am investigating Eastwood products) will be to pressure wash the frame after cleaning it as best I can and then rinse with distilled water which is slightly acidic and allows a formation of a different iron oxide and immediate drying by rags and air, then apply the protective coating both inside and outside the frame. I will only use sandblasting when I have to because the body is fiberglass and will need protection when I do. I will probably do a few feet at a time, (hey, I'm retired, work is a four letter word) and I may experiment with doing what sandblasting is needed before starting or just before painting.

The biggest problem I have is finding technical or user information on the various products. All the suppliers say their product is best, but give little to back it up. The main thing I have found is that the heavy tar based products are worse than doing nothing at all. The various paint products have promise as do the fairly plain metal preps based primarily on phosphoric acid. This does seem to etch the metal and improve adhesion. I have used it on car bodies in the past and had good results.

If anyone has used any products for frames, I would be glad to hear comments good and bad. Currently I am looking at Eastwood and KBS products but will include any others I can find.

Salts ARE neutral many are still corrosive. You need to remove the salt not neutralize it. Phosphoric acid will change the rust to a more stable iron phosphate. It is in several rust treatment products.
