Here is a different way that I have found to take the rust off of metal.
First you need to get a few things.
The key ingredient is ďArm & Hammer WASHING Soda.Ē (Not baking soda)
This can be hard to find but Iím sure one of your local grocery stores will have it.
This is what you use to make your Electrolytic solution.
You will also need 2 pieces of scrap steel and some wire.
A plastic tub full of water.
A 12 volt car battery charger.
Mix Ĺ cup of washing soda to every 5 gallons of water in your plastic tank.
Connect the two pieces of scrap steel together with the wire. Use enough wire so they will be able to sit at opposite ends of the tank. (These will be your electrodes)
You will need to connect your battery chargerís POSITIVE clamp to the wire between the 2 electrodes.
Take the trap or traps that you want to de-rust and connect a wire to them. Place the traps in the middle of the tank of water. Connect the NEGATIVE clamp to this wire. ** Keep the clamps of the battery charger out of the water or they will corrode.***
Make sure that the wires or metal is NOT touching the electrodes or you will have a dead short.
Hereís what it should look like.
Now itís time for the bubbling! Turn the battery charger on (I set mine on 10 amp).
This should take about 24 hrs to complete.
Here are some step by step pics that I took of an old #11 that I found on the river.
This trap was too far gone but I thought it would a good one to use in a pictorial.
Notice how bad the rust is.
Here are my scrap pieces of metal connected by wire.
Here is everything hooked up and ready to plug in.
This is after about an hour of bubbling. Notice the nasty rusty film on top of the water.
And after 1 Ĺ days here is how it came out.
Take a wire brush (or a power washer if you have one) and knock off the rust that is still there.
It will be really loose and takes no effort at all.
Here is our #11 after a couple of minutes of wire brushing.
