Electrolysis

[adrianreeve]

I did my sierra front and rear hubs, and have just done all four calipers - it's brilliant and will send you looking for more rusty stuff to do!

If you can, I would use a sheet of mld steel rather than strip, as you will get quicker results.

The great thing is the process won't attack good metal, so bearing surfaces etc are unaffected

Cheers

Hi all one thought on drusting parts ,if you know any one with a saftykleen degreaser,they do a liquid derusting soloutin which we tested for them at work,i thought it was going to be a gimmick, but it was brilliant and did what it said on the tin all you do is drop the part into the solution and leave it do its stuff .

Yep, it does not etch rust and metal, it reduces rust to metal.

Has anyone got a list of things you need for electrolysis? I'm trying to find a list and a guide but i can't seem to find one.

Also does it damage rubber seals etc? Finally what parts am i allowed to do? I know not to do disc brakes or the flywheel as they could suffer from hydrogenation (i think) and become brittle and shatter . My plan was to do the brake callipers, brake drums, front uprights and some other stuff if it works well.

all you need is an 12 volt car battery charger, baking powder, a container to put your parts in and some scrap steel to surround your rusty part.

connect the + side of the charger to the metal surrounding your object and the - side to the object. pour the solution of water & baking powder into the container with your object and leave over night.

DO NOT USE STAINLESS STEEL THOUGH!!!!! it turns your water very toxic & harmfull. also dont get you + & - mixed up or your rusty part will be eaten away!

What else can i use other than a 12v car battery charger? As i don't own one at the moment.

Cheers for the guide tho.

Here is an interesting artical in PDF format

Elecrolytic rust removal

This should help explain the basics & give a general idea of what is needed

[dan_g8]

you can use anything that puts out arround 12 volts, 2amps & is DC.
