Was told that people in the forum would have instructions for setting up a tank using water and battery charger to remove rust from metal fact or fiction.
Yes, I have one. It works great. I use rebar for electrodes (Don't use stainless). I have a 30 volt power supply that runs it. My tank is about 4 feet long and 2 feet wide. Arm & Hammer "washing" soda not baking soda. The rest you will find from the above link that Thunder put up. Several of us use this.
Here is a link to this subject that was brought up on last years forum. There is a lot of really good information on how to set up and all of the materials needed with plenty of good results.
I have used it many times really neat to see rust reform to metal
If you get Arm & Hammer "Baking" soda, you can bake it in the oven for a while, this will convert it into "Washing" soda.... Dont ask me how or why this works, but it does.
I read that on one of the links somewhere. But it has to be Arm & Hammer....
Thanks guys Paul Vitko said you would be able to steer me in the right direction.Can"t wait to try it out on some castiron pistons since we can"t use aluminum pistons for our racers, club rules.Also seems a great way to clean up transmission found laying outside for years.
I just use a cheap switchable 2 or 6 amp charger and a 30 gallon plastic storage container. It seems to work best on the 2 amp setting. it takes a couple hours for really rusty parts, but does an amazing job. After final cleaning, I treat it with a phosphoric metal prep solution.

Here is the link to the actual article explaing how to set one of these up.
I use a charger that I got from Harbor Freight. It has settings for 2 amps, 10 amps and 55 amps (intended for starting.) Using the 55 amp setting really speeds up the process.
I. too, like to use sheet metal for the sacraficial annode. The amount of surface area seems to make a difference. Then you can clean the sheet metal with a disc-grinder or belt-sander to get a good clean surface.
Make sure you get the connections correct. The way some people do it is to use Re-bar for the sacrificial annode. So rememberer, Red goes to Re-bar.

I’ve mentioned this in previous posts, but will add it to this thread as well.
If your charger is of the ‘polarity protected’ type and does not have an over ride
switch, it will not work. These chargers expect to find a battery with enough
power (and correct polarity hook up of the leads) to trigger the charger to start.
Hooking the charger to a battery and the battery to the electrodes will get around
this problem. Just remember – no sparks or flame – you now have 2 sources of
hydrogen and oxygen. Always make sure you have adequate ventilation and do not
cover the electrolyte container when in use.
Excelent points Art. Rick, be sure to read everything on that link that was provided. I've used the process a few times myself, with excelent results. I have a large tub that I set up outside the shop. The trick is to find the right tub for the parts being cleaned.
i have no washing soda and only a 1/2 gallon container so i used washing powder and found the reaction stopped after half an hour. Where did i go wrong? Does the water need to be a large volume or replaced? Or is the powder more important than i first thought?
Maybe you can check in your kitchen for some Arm and Hammer baking soda, it works as well as Arm and Hammer washing soda. I don't know what washing powder is but if it worked for awhile maybe you have a bad connection or lost power.
'Baking Soda' is Sodium Bicarbonate.
'Washing Soda' is Sodium Carbonate.
I have used a mix of baking soda and electrosol dishwashing powder, works as well as washing soda I thought. KB
Adding some salt helps the entire reaction considerably. In my 100 gallon tank I use two cups of washing soda and a cup of salt. I just put more in when it quits working so well.
I don't know where the "Has to be Arm and Hammer" came from, but I disagree with that statement. I cannot find washing soda in my area, but either "ph up" or "ph down" (Sorry, Chemistry wasn't my strong suit) for swimming pools is Sodium Carbonate. Your local pool store or even Walmart (Although I avoid them if at all possible) will have it. It worked fine when I tried it.
I have used Ospho for changing rust for years. Buy it by the gallon and brush it on lightly...works great!
