Electrolytic rust removal FTMFW

[kotu100]

Wasn't sure where to post this since its not really mk3 related, but i know it will be handy for ALOT of people that don't know about it.
a process called electrolytic rust removal.
with a bucket of water, some baking soda (washing soda works better), some rebar, and a battery charger you can clean rust off damn near any steel part you have.
the best part is, it removes absolutely NO good steel, it only takes off the rust.

using youtube and google i found how to properly do this procedure. anyone else done this before?

i anodized some aluminum parts in a similar fashion. nitric acid, sulfuric acid, and a lead cathode though.

Any more info such as procedure?

Is this for only small parts or will this work on body parts aswell?

im acutally gonna be setting something up so i can do parts as big as engine blocks, and my rear subframe. maybe i'll be able to salvage those camber bolts after all.
saw an article where this one guy made a setup that held 1600 gallons, he was doin a trailer frame.

i did it on a rusty cam, its useable again

those camber bolts are plain gone mine were. had to break out the die grinder and an extremely thin cutoff wheel. would this be able to unseize those bolts from the bushing sleeves?

and holy hell, 1600 gallons? couldnt you sandblast it?

I did this with an old header for my Z. Worked great. Just make sure you clean it after you done and then paint it. Or it will rust again.

it could be sandblasted, but that takes time, and costly equipment. it also removes a lil bit of material as well.
with this process, it will probably take me an hour to set up (mostly filling container with water) then i just let it sit for 24-36 hours. it does all the work for me.
yes... im VERY lazy :biglaugh:

we built a sandblaster out of a 40 lb propane tank

i've definitely seen the metal come off when sandblasting, but i was thinking for the scale of trailer frames it might be more efficient to have someone blast it for you.

however, i'm definitely gonna tinker with this.

I have done this for testing only so far, but I will continue with this soon.
Look in my project thread here for pics.

Don't drive it in, you got to put a brick on the pedal and let it drive itself in if you want to see all the rust is gone after you figure out how to get it out.
