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. |
