WhO's THE BEST, rust remover/ encapsulator Options

[mrgjones]

Alright. There are a lot of products on the market that promise to remove rust and prevent it from coming back. From reading the threads it seems the opinions on this forum are as varied as the products themselves. This thread is about making a convincing argument... or a ludicrous allegation, which ever you find appropriate. Horror stories are welcome but please limit yourselves to the chemical rust abatement theme already established. For you slow starters, here is your motivation.

Actuallly, if you do it long enough, the black turns to slime that can be brushed off with a wire brush. I like the copper bristle brushes as they seem just about right. You need a lot more time with that sponge or you need to fill the drain hole, fill it with solution and float the positive electrode over that hell hole on a foam block.
With the big tanks, foam floats can float the positive anode over the part. Was able to clean my 48 inch mower deck that way by moving the float. Took about a week.

When you are done, the metal is bare and gray, and you can actually see the rust pits are conical. It's those conical pits that prevent sandblasted sand from getting all the way in to the root of the rust cell.

Want toxic? Add zinc to the mix. The factory used a gray primer that contained zinc and it takes a good while to get it softened up and off the parts.

The stainless holds up under the current and I have yet to eat much off of one. The lye eats the paint at a mix ratio of 1 Tbs per gallon.

And to make it go faster, I use a high power prototype electrosurgical generator.

Per the baking soda, rust removal slowed to a trickle.

Tried the spoge thing for years but it usually boils dry pretty quickly. Even tried a fish tank pump and a stainless tube as a spray device. Pumped the conductive solution out of a bucket, and into a rubber tube with a stainless tube at the end. Clipped positive to the tube, negative to the car and sprayed at the side of a car. Solution trickled down the car and back into the bucket. Didn't seem to work at all.
