General De-rusting of parts. Rust removal methods.

I'm keen to try molasses, it combines with the rust and makes it water soluble. Apparently its great for engine blocks as you can de-rust inside and it doesn't matter if some is left in crevices as its not acidic.

I keep a 5l paint tin with a 50/50 mix of acetone and hydraulic oil to throw in small parts. Gets off a lot of surface rust. I like the idea of electrolysis though....definitely going to have a go at that.

The thick rust flakes are best chiselled off first with a needle gun or manually with hammer and chisel.

on I like an ammer.

The first time I tried the electrolysis method I was a bit underwhelmed as it seemed to do nothing. I tried again but this time I put the battery charger onto a battery and then connected everything up and it worked great. I degrease everything first and then wrap wire around the item and in it goes. The carrot soup it makes is pretty gross though! Ive put in anything that will fit in the pastic crate I have set up.

I found with a modern battery charger you have to go through a battery first. With an old style charger you can go direct to the part.

Hmm carrot soup, I think this was a back plate.

I now have a 200ltr drum that I use. I needed that as I was derusting an axle case. I had to do one end at a time but it worked a treat.

Any steel parts I now take off the land rover get electrolysis, phosphoric acid solution, de-greased, abraided then painted with red oxide.

I usually use phosphoric acid after too, unless it's for bolts, then it gets Flag metal primer which is very thin and gives a good blacking. Zinc type bolts get phosphoric acid then sprayed with zinc primer.
