Rust Removal

Part1.
Most of you have probbibly done some copper plating at home or
even school but did you know that you can remove rust using the
same process by using items that you possibly already have at
home.
I decided that i wanted to re-build my 350W Hawt but it was
covered in rust and several layers of paint and i just wanted a
cheap way to remove all this crud.....This is when i found out
about Electrolysis rust removal and decided to show a few
pictures of a brake drum from a 1980s escort van that was used
to try and show a before and after on the same workpeice (Just
for you guys).
How do i do it then......
1. get yourself a plastic tub that is larger than the item you
wish to de-rust.
2. Find some sacrificial steel or iron (Rebar in each corner is
a good way to go).
3. Get a car battery charger or and DC low voltage supply (about
2-6 Amps will do).
4. Buy / Beg / Borrow some soda crystals or super washing soda
(Rock salt or even table salt will work at a push).

Part2.
Fill your tub with fresh water and fit the sacrificial steel and
conect the + (Red) of the battery charger to this steel.(it
needs to be line of sight for the rust to be removed).
hang your workpeice in the water and connect the - (Black)
teminal to this.
At this point i usually switch the charger on but there should
be no current draw just yet.....Add a little soda or salt and
stir....keep doing this until the amps are 2-3 amps and you
should be good to go. (The lower the amps the longer it takes).
Leave it to cook in the soup for as long as you can (It will
never eat pure steel or iron....only rust), 24hrs would ensure
all rust has gone and turned into a black oxide.....remove item
and wire brush while it is still wet and see the pure steel come
back to life.(It removed several layers of paint on my turbine
hub too !!).
Dont forget to oil or paint the item almost straight away as
even a few minutes will see rust forming again.
Go find those old rusty tools or turbine parts and give it a
go.....You wont regret the outcome.

Cool! I used this way 1 time and it worked ok but I didn't know
what I was doing. I like the part where you kept adding soda
till you brought up the amps! Next time I will give that a try!
Also do this in a well ventilated area I think it produces
hydrogen gas which is flammable! Nice job NP thx.

@sut
Yes you are correct about doing this process in a ventilated
area......I thought I had covered the main process but ended up
not covering the health and safety side of things......Thanks.
I also understand that all the waste from this (water / sodium
carbonate and iron) is safe to be given to your garden but then
again I am not a chemical wizard.

Wow! This is a great tip. I definitely will try this. I hate
removing rust with a wire brush and sanding.
