Re: rust removal by electrolysis
that's my understanding, the electrolyte simply provides a path for the current flow and is not used up in the process.
Sodium carbonate is also called "soda ash". In swimming pools it is used to adjust pH. Captainfab, you have a pool or any neighbors with one? Wal-mart or Tractor Supply might have this stuff. The Arm & Hammer laundry detergent I use contains both sodium carbonate and sodium bicarbonate (the baking soda part), but doesn't say in what proportions.

Re: rust removal by electrolysis
I checked out one of the local Ace Hardware stores today....no washing soda. I didn't have time to see if they could order it for me. I may either go back and see if they can, or else order it online. I found a few places on line to get it from. I mentioned the KOH and NaOH since those are the preferred additives to create a good electrolyte for hydroxy production. I may give that a try sometime just to see if it works for rust removal as well.

Re: rust removal by electrolysis
I found some Arm and Hammer Super Washing Soda today for $2.69 a box at Fred Meyer's. You guys here in the NW will recognize that name. Sorry it doesn't help the rest of you.

Re: rust removal by electrolysis
Mixed the solution in a small plastic barrel. Formed two rings from 1/2" round hot rolled steel. Welded a vertical 1/2" rod to the two horizontal. The vertical rod rests on the bottom of the barrel suspending the first ring 5" above the base of the barrel and the second ring 3" below the surface of the solution, then extends out of the solution a couple of inches. Connected the positive to the vertical rod and the negative to the parking brake cable suspended in the center of the barrel to the battery charger. No bubbling, no reaction. Hooked up the Lincoln AC welder lowest setting in the same manner after removing the battery charger. Instant bubbling, rusty foam to the extremities within a minute. The welder is to strong. The solution is hot to the touch. There was a green slim on the parking brake cable after a couple of tries at it. Do the multiple strands of a parking brake cable create a resistance that heats everything up? Is there something I should be looking for in a battery charger that is compatible with this process?

Re: rust removal by electrolysis
I have used two different battery chargers, both Century 6/12 volt with no problems . One is 2 / 10 amp and the other is 2 / 10 / 55 amp. Always set on 10 amps and never drew over 2-4 on the ammeter gauge
As to the heating question . I have not ever checked temperature of the solution.The solution is a resistor that conducts current flow so it would make sense that it would heat up while in use. Voltage pushes Amperage through Resistance. And resistance = heat With a welder it may heat up real fast in a small vessel. How much did you mix in your water? and I suppose the water quality/ hardness varies in regions. This may require some trial and error in the mix ratio Post #34 has a picture of the battery charger I use the most.. And I found things work better when the outer grid begins to deteriorate and "break In"

Re: rust removal by electrolysis
Aerotruk, the only problems I've encountered had to do with either the connection at the part that needs cleaning or the grid becoming fouled with transferred rust. Since your grid is new it obviously isn't the latter problem.
I wouldn't think the solution is the problem (that was an unintended pun, sorry) as it would have to be pretty weak and I'm assuming you mixed per instructions. When you tried hooking the battery charger up, did it indicate any current flow? If not, then the problem is most likely at the point where the charger attaches to the part. I've gotten into the habit of cleaning a spot on the part so the connection is good and wiggling the battery clamp around until I get a response from the charger. As soon as the charger indicates current flow the bubbling should start. Like Bubba, my 10-amp charger has never indicated more than about 4 amps. I might be wrong, but to me the rust on the part offers the first line of resistance which the welder easily overcame, perhaps in part because the welder clamp itself provided a better connection. The green slime is interesting. The outer portion of the e-brake cable may have a coating (zinc maybe?) that may cause the slime.

Re: rust removal by electrolysis
Thank you. I thought of using a rheostat on the welder to try and reduce the amps.

Re: rust removal by electrolysis
It is a easy way to clean stuff! I have no problems with paint adhesion or rust through.
I was reading something about the caustic properties of Coke and its use as a rust remover and cleaner. I have not tried that yet.. I will see if I can find the article and post it

Re: rust removal by electrolysis
I use mine occasionally, I cut a 55 gal poly barrel down for mine and it worked very well.

Re: rust removal by electrolysis
I found the article i was looking for about using Coke for a solvent and rust remover
http://antique-engines.com/rust-coke.htm This is from "Bills electrolysis pages"-- The same site where I found out about the washing soda system ( while on this URL click on the "back to Bills electrolysis page" icon to take you to the original article) I have read that that Coke will clean a lot of things including hard water spots in toilets, clean your chrome, dissolve battery acid ETC. I won't drink it any more after my kids dissolved chicken bones in it for a science experiment. ![]()

Re: rust removal by electrolysis
Works for me! 24 or so hours, 12V@2A. See for yourself. Pics are a bit soft due to lens frosted(cool to warm environment)but you get the idea. I took my dollar store wire brush to the bracket to clean a little of the black by-product off after rinsing in cool water, the whole process is a breeze.

Re: rust removal by electrolysis
There`s another process that I used several times when not in a hurry for a particular part, plastic bucket 2 parts water one part molasses, takes about a week, when done rinse off, does not rerust over again either, contents can be dumped in drain or lawn, ( not responsible for ants )

Re: rust removal by electrolysis
You will need to use an old school type charger. The least complicated the better. Be sure to keep your connections above water, dry and clean, metal to metal.
The modern electronic chargers that check alternator function and provide a bunch of other data will not work as they are designed to recognize this type action as a fault. As a safety precaution , they show a fault code & do not deliver the voltage. |

Re: rust removal by electrolysis
Just a heads up on the power supply. A battery charger is convenient(I lack one though) but I used a 12V switching power adapter from some computer peripheral to get my desired results. I have since upgraded to a Duracell 16V@4A NiCad charger/adapter, I can see improvement in the chemical reaction(bubbles and gas generation)It is permissible to immerse the negative connection-keep to positive connection dry.
If you are interested in the 12V-2A adapter, just PM me and pay the ride via 1st Class Mail. I can include some washing soda to get you up and running, just add water. |
