De-rusting by electrolysis


Johnny

Recommended Posts

I ran a little experiment last night.

I've read that you could "de-rust" objects with very simple means, and I thought that I'd try it.

The material I used is very basic:

-A cheap battery charger

-some scrap metal, which I bent to a crude circle

-5L of water

-one tablespoon of washing soda

-one 10L plastic bottle

-one rusty rear caliper from a 505 turbo ^^

The setup looks like this: (the caliper is submerged)

When I picked it up after 16 h it looked like this:

I put it in for another 4 h, and then when I picked it up, rinsed it under water and dried it with a heatgun it looked like this:

As you can see, there is still some light rust left on the surface, so I gave it a round with the rotating wirebrush, and then it looked like this:

I gave it just a few minutes of work with the wirebrush.

I forgot to take a "before"-picture, but the caliper was pretty much covered in rust, the worst loose rust had been brushed off it.

This is a non destructive cleaning, so none of the "good" metal is not eroded.

I think it worked suprisingly well, and I encourage you to try it.

It sure looks amazing :rolleyes: , have you tried it yet?

Ya. I bought a 1/2 pint or so localy before I sprung for a couple of gallons. Works just like they say. The process is salled chelation which chemically severs the rust from the metal.

I've got a couple of gallons on order. Have some nasty bigger pieces I'm going to try next. I'll add to this thread with some pictures.
