The battery charger works, all kinds of videos on line with the fine points of it. Tried it once and found some thing I did wrong but it still worked just took longer and more adjusting, didn't have enough negitive posts in the water and had to turn it a lot. Ed

Go to YouTube and search for "rust battery charger". You will get several videos on the subject.

Another option is evap-o-rust. I personally have used it and it works great. It's not cheap at around $20 per gallon but can be reused over an over.

I have used SKYCO Ospho Rust Treatment Ospho Rust Treatment - Since 1947 Found it to be very effective.

Many of the new chargers may not work for what you have in mind.

Don't know the scope of your prodject but applying phosphoric acid will neutralize rust and leave a coating. Lots of other acids that will also work.

Depending on what you are trying to clean up, but good old Muratic acid is a cheep rust killer. After I get the majority off with it, I also use a final Phosphoric acid dip to "convert" rust to a stable oxide.

I just restored an old Griswold cast iron waffle iron. It was so rusty I had no idea if it was even good still or not. I just put it in a bucket that was about 75/25 distilled vinegar and water. About 3 days in the solution was bubbling and turning foamy with the water being rust color. I pulled it out and was amazed what a treasure I found. Couldn't even tell the thing was over 100 years old.

If you have the time, vinegar and water works wonders and it's non-toxic.

Another good rust remover is liquid molasses from a feed mill mixed about 8 water - 1 molasses. Works very well over time on is also not toxic.

Diet coke: Non toxic (well you could argue that) and not sticky.
