Can i also use agricultural salt ( the kind you use to conservate silage and comes in 25 kg bags) as a conductor, or would that cause continuous corrosion once you take it out of the bath ?

I can't answer that question but Arm & Hammer washing soda isn't that expensive.

What's the chemical composition of washing soda ? i'm not familiar with this stuff, at least not the English name of it.

Washing Soda = Sodium Carbonate
Baking Soda = Sodium Bicarbonate
Around here, Washing Soda is found in the cleaning materials section of the supermarkets.

I keep wanting to do one of the projects, whenever I'm in a store and I think about it I try to find the A&H Washing Powder, but so far I've had no luck in finding it. 
I've check Kroger and Wal-Mart - and Lowes (I thought maybe by chance). Might have to check a little Mom & Pop grocery store to see if they carry it.

Guys, I am pleased to contribute a discovery.
If washing soda is indeed sodium carbonate then I have a great source for you. I buy it in containers of about a half gallon. The stuff, sodium carbonate, is also what the commercial coffee pot cleaners are made of. The place I buy it for cheap is walmart and it is......
Pool pH increaser.
The big plastic jug of fine powder used to increase pH and should be available year 'round at pool stores and seasonally (at least) from walmart where I bought my last jug. It is cheap. I have even found it at home depot in their pond section.
I originally bought it to raise the pH in my hot tub and I have used it several times in my drip coffee maker to get all the nasty oils and stains to dissolve.

Highbeam,
That is a great discovery. But, I got to thinking... with our pool (I sure miss that pool) I always added "Alkalinity Up" which is Sodium Bicarbonate to increase the PH. If you go to the pool supply make sure you get the Soda Ash which is Sodium Carbonate. I did a search and lesliespool.com had different quantities up to a 50lb bucket for $50.
Mike,
Thanks for making me remember my high school chemistry. For one project I took two test tubes filled with water and inverted in a water and sodium carbonate filled flask. Put a "J" shaped coated wire with a bit of exposed wire into each test tube and connected a small 12 volt battery. A little while later the water in the test tubes was replaced by oxygen in one and hydrogen in another. I then lifted the test tubes out of the water and inserted a lit match. And of course the oxygen one burned more intensely and the Hydrogen one popped in a small explosion. Water, electricity, gas, and fire... Great fun!
Now pardon me while I go and try to find some big rusty pieces of steel and run by the pool supply store.

Hey Mike, what happened? Did the snow plow dissintegrate? Give us an update.

Glowplug the majority of the parts have now been removed from the "soup" pressure washed, and primed. BTW: The process only removes rust, it will have no effect on the steel itself so there is no fear of disintegration.
They are just waiting for an opportunity to be painted. The electrolysis process was slow with the larger parts, like the blade itself but I was also working with a smaller battery charger. The process ate roughly 30' of rebar and the cleaned parts were remarkably rust-free, and after pressure washing looked like new.
I'll post a picture or two after painting.

Yeah, I know. I was just makin' a funny. Looking forward to the pictures. You don't happen to have any without the primer, when all the rust was removed after brewing in the soup do you?
