How To Remove Rust

How To Remove Rust

Watch Kevin Tetz from PowerBlockTV's Trucks! demonstrate the art of rust removal! Get rid of rust sooner rather than later with VideoJug's assistance.

Step 1: What Not To Do

Now here's something that is not going to cost you a dime other than the cost of some simple household cleaner.
If you've got a vintage vehicle that has suffered from the old tin worm, rust, well you know you've got to do something about it. As the saying goes, rust never sleeps.
Now what a lot of guys will do, is grab a grinder and grind off the rust as well as a healthy portion of good metal too.
One of the problems with that is you can leave rust in the pits of the metal and if you try to prime or paint over this it's going to cost you problems down the road.

Step 2: Prepare The Tank

To remove all of the rust without removing any of the good metal all you need is a tank that will hold your part, a 12-volt battery charger, capable of at least 2 amps of constant current and sodium bicarbonate.
Now in the grocery stores, this is know as washing boost or washing soda. In our tank we have 1 teaspoon of washing soda for every pint of water.

Step 3: Prepare The Solution

Lay your part in the solution and hook up the negative lead of the charger to the part itself, and the positive lead to a steel rod that is set in the water.

Step 4: Set Your Battery Charger

Now, set your battery charger to a constant 2 amp service and let the work happen.
You'll start to see bubbles form on the contacts and rusty surface. This is hydrogen forming an out gassing into the solution so make sure

Step 5: Watch For The Results

Now our control arm has been in the tank about 48 hours. Smaller parts aren't going to take you as long.
You can see where it's turned black. All of the rust is gone. And none of the good metal has been disturbed or altered in any way.
