Hi folks, I want to get a rusty Farmall H block going today, I got a 55 gallon plastic barrel that I am going to use as a tank. Heres my question, how good does Arm and Hammer Baking soda work for this?, I have heard washing soda works better, but I don't have any of that on hand and don't think the local grocery stores even sell it. Ok, now how much should I use, I figgure I'll probably need to fill the barrel about half full, and I'm going to put the block in before I start filling it so there will be probably about 20-25 gallons of water in there, I don't think I want to fill it much over the top of the block. Would a 1 pound box of baking soda be enough?. OK, next question is what setting on the 12 volt battery charger should I use?, I got a 2 amp, a 10 amp, and then of course start.
Thanks!

Hey the guys on the 8n ford forum have dicovered this method too, you might search there and get some good links. Once you catch on to it you will never go back.

Have you checked out Frank-in-Tallahassee's website on electrolysis and lye gravy?

Yeah, I know the site's GREEN, but his techniques work on RED, too!

You boys talk about this technique like it is a well known thing. I am 74, average intelligence, and spent most of my life on farms and never heard of this procedure for derusting. Sounds like a good approach. Would appreciate a explanation as to how this works and what is happening. I do know oxygen will but burn but acccelerates burning so that wouldn't be a problem but hydrogen certainly would be. thanks

i would advise against doing inside as when it is working it is giving off hydrogen gas,and your father can tell you what happened to the HINDENBERG

Hi JF, get the washing soda, I use Arm&Hammer. A lot of places do have it. Seems like you use baking soda to remove paint? I does not matter how much water you have as long as it is submerged. I use a pound for fifty gallons. I use a big sacrificial anode, and in your case something that wraps around the inside of your barrel would be dandy, you can get a lot of surface area and get away from the line of sight deal. You may want to use smaller anodes inside but not touching the block to get good coverage. Try moving the anode around in the tank to find the spot that draws the most amps. In my opinion if you are only pulling six or eight amps you can do it faster with a wire brush. More amps equals less time. I cleaned one whole engine that was rusted solid, had been buried for who knows how long. It drew between 40 and 90 amps for three weeks, but when it came out it was disassembled in 30 minutes with no breakage whatsoever. Remember when it is drawing a lot it is also giving off a lot of hydrogen, so vent accordingly. Play with it a little and you will swear by it.

I was planning on setting this up inside the shop, but my dad likes to smoke in there and we also have a wood stove that is still in use as it still gets alittle cool some nights. Would this be a safety problem?, the woodstove is at the other end of the shop, probably 20 feet away. I will try to local a box of washing soda and try it. This will be my first electrolosis experiment, the block is totally dissasembled with nothing on it. One other question, when I get it done, what should I do to it to wash it off?, if I use a hose, it'll probably form rust immediatly again.
Thanks

Yeah, take it outside. It will try to rust real fast when you take it out. The link above does have some pretty good info. You can go to Harry's old engine page, get on the Smokstak and do a search and you will have a lot of correct info too. A lot of people use a product called Ospho for the phosphorus nuetralizer, I pull mine out and run for the hot water pressure wash and then oil it immediatly.

Do not do it in an enclosed space. As the water is broken down, it also gives off oxygen. Not pleasing to ignite.

By the way there is very strong evidence that the fire of the Hindenberg was a flash fire of the chemically treated skin (the effort to make it conductive, and UV resistant caused the builder to experiment with Iron powder, and aluminum powder in a matrix of laquer, on the canvas. The mixture is a very good imitation of rocket fuel. Look it up in the library in Scientific American Magazine.

The movie of the event shows the skin flashing bright orange, the hydrogen would be near invisible light blue. The US space shuttle uses Hydrogen/oxy fuel in the main engine, and Iron aluminum in the boosters!!!
