De-rusting bucket.

Post by rotciv »

I saw this process of removing rust with an electric current on the internet and decided to try it out. It takes time, but i found it very efficient especially for rusted parts that have awkward recesses where you can't reach with sandpaper or a steel-brush.The only things you need are a battery charger, a plastic container, another piece of scrap iron, some tap water and a couple of spoonfuls of table salt.

This pic shows how the re bar sits on the bucket. the vertical pieces all round ensure that the suspended part has an all round reaction because if i just suspended a piece of iron on oneside of the part, the side nearest starts to be cleaned before the opposite side taking longer.

This pic shows how the part is suspended before the water is added.It must not touch  the re bar connected to the negative.

This pic shows the iron inserted into the water,and the charger connected with the +positive to the rusted part and the - negative  to the circle of iron re bar around the inside of the bucket. here bubbles start forming at the negative and the water starts to get a rusty greenish tint.

this is the rusted piece of iron that i tried after four hours in the bucket.It needed more time to be fully cleaned, but you can see that it has worked. this piece was very heavily rusted as can be see on the pic on the places which are not totally cleaned yet.

I saw this method on youtube a while ago and was impressed by its efficiency although I should already know that it would work (and how/why) given my electronics/electrical background! Still, it's nice to see a good example from a forum member - excellent result! :thumbright:

I wonder if I can get a bucket big enough to take my car..... :scratch:

You can use a similarly simple method for Silver: line a non-metallic vessel with "Tin foil" put the Silver in, add some Bi-Carb and then hot water, (1 tbsp of Bi-Carb per quart) then just leave for a while.
One day it will all be firewood.

Thanks, i don't have any electrical background just elementary knowledge in electrical matters, but i like to try things out and it gives me satisfaction when they work.

As for the car, you could borrow your neighbor's swimming pool. :-)

I assume that the above is for cleaning tainted silver. Do you use any electrical current in this method or just dip the silver in the solution?

That's a great result!

I remember when you did something similar, a few years back when etching a helmet with seawater :thumbright:

Yes Chez, your memory is spot on. Etching,Plating and de-rusting are similar processes but the electrodes,solutions and polarity have to be according to what process you are doing. I think the result would have been much better if i had given it a couple of more hours.
