Roger,

For breaking loose seized fasteners/joints a good soak in 50:50 mix of acetone & ATF has never failed me yet. For heavily rusted object, not sheet metal, shot blast, for sheet metal (thin) bead or soda blast to avoid warp potential. Small items can be wire brushed or soaked in vinegar, [b]very [/b]dilute hydrofluoric acid, HCL, Ospho, or a wide variety of derusting products from hardware stores, e.g. Navel Jelly.

If you prefer avoid toxic chemicals, & can find a radiator or engine builder that still has a "Hot Tank", that will do a great job, or electrolysis:

For car panels dustless blasting looks like good option, if can find someone who does that service:  https://www.dustlessblasting.com/  or  https://www.youtube.com/watch?v=nucYBS4B0bc

I have used extensively washing powder by Arm and Hammer ( Sodium carbonate NOT sodium bicarbonate ) and a battery charger . One cup of the powder in a 5 gallon bucket with regular tap water . negative lead to a piece of steel in the bucket and the positive lead to the item you want derusted. Takes a few hours, does and excellent job and is cheep.

This sounds interesting but am I missing something?  Wouldn't the item to be derusted be submerged in the solution? -------- Original message --------From: "Michael Ponsano michaelponsano@gmail.com [mg-tabc]" mg-tabc-noreply@yahoogroups.com> Date: 4/21/19 12:34 PM (GMT-05:00) To: "mg-tabc@yahoogroups.com>" mg-tabc@yahoogroups.com> Subject: [mg-tabc] Re: FW: derust   I have used extensively washing powder by Arm and Hammer ( Sodium carbonate NOT sodium bicarbonate ) and a battery charger .

Yes, the item must be submerged in the solution. My experience is that it takes much more than a few hours - more like a few days. I had best results with small items like nuts and bolts. Charles Hill On 4/21/2019 1:00 PM, peterfx20 peterfx20@yahoo.com [mg-tabc] wrote:

Many thanks for your comprehensive reply Bill, Very helpful.

There are so many variables. The amount of corrosion, the amperage, the strength of the solution. But what I like is that it is inexpensive and kinda fool proof easy. I also use it to degrease parts. What I have done to a great degree of success  is run a part through the solution , wire brush it, run it through a bath of hydrochloric acid to remove the zinc plating ( if any )  and etch it, run it through the solution again , rinse and then re-plate. Either nickel plate, zinc or copper.
