Best Charger for Rust Removal by Electrolysis

This is not a tutorial for removing rust from metal by electrolysis (electrolytic rust removal). There are plenty of them on the web and Youtube. Rather, it seems that every how-to for rust removal leaves you wondering what power supply works best for removing rust from metal by electrolysis. I have done a lot of research and have personally tried several of the suggested power sources. Below is a link to the power source I have finally decided on. It is a manual battery charger and is available on Amazon. Scroll down to see samples of the positive testimonials it has received from buyers.

The problem with most battery chargers is that they are “too” smart for rust removal. They realize they are not connected to a battery and refuse to produce power. This problem is solved by using a manual battery charger. A manual charger produces power anytime it is plugged in. This can be a problem if you’re charging a battery (overcharging), but is perfect for electrolysis.

I highly recommend the Schumacher SE-82-6 Dual-Rate 2/6 Amp Manual Battery Charger for rust removal. After you’ve tried it, please leave a comment and let me know how it worked for you.

– With everything automatic nowadays, this charger is refreshing change of pace. I had a lot of rusted machinery tools and parts that I wanted to de-rust using electrolysis and needed a manual charger to supply the needed current for this process. This charger is the workhorse for this method.

– Perfect product for my small electrolysis tank. Used it to remove rust from some older tools. Sturdy constuction. Thick metal casing. 3 settings. No on / off switch (unplug to turn off). Low priced. Pretty much fits my needs. I also use it to charge my boat and motorcycle batteries.

– I needed a charger for my electrolysis tank and this works perfectly!! This is manual and will not shut off until you unplug it. Just what I needed! Thanks

– I bought this to use for electrolytic cleaning of old metal. That requires a manual charger instead of the smart chargers that are common now. It worked great for that purpose. I shorted the leads together a couple of times by mistake. The internal breaker kicked off, then back on again once I removed the short, with no damage.

– I used this for electrolysis to remove rust from auto parts of an old VW I was fixing up. Worked great. Definitely have to get a charger that is manual.

  1. Thanks! I went with your suggestion, I actually appreciate your specific suggestion, as I did not have to try and figure out which was a manual…yada yada…

  2. It does a good job but I’m wondering if more power would do better??? I’m really not an idiot, I just have
    a warped sense of humor. I’ve tried other chargers and set ups but this one seems to be the best so far.

  3. I’m currently building a reverse electrolysis system and I have a question ! I just bought a battery charger that you recommended, and as you have mentioned in your site, I do not intend to submerge the red ( positive ) alligator clip . What I’m wondering is whether there will be a negative ( pardon the Pun ! ) impact on the black ( negative ) alligator clip to which I’m attaching the object to be cleaned ! I’m generally going to be cleaning small objects such as coins, metal buttons, etc. That I’ve found metal detecting ! This means that the negative alligator clip will have to be submerged for the most part ! I don’t want to have to replace this clip and ultimately ruin a good battery charger ! Any advice or suggestions on this issue is greatly appreciated ! Ps. The charger I bought is a Schumacher SE-82-6. Thanks for any input you may have !

  4. I bought the SE-82-6 and it worked great for about two hours and then it just stopped working.

  5. Sorry to hear that. I’ve been keeping track and, so far, about 3% of the people I hear from say their unit quit working after a while. From what I’ve been told, the manufacturer is pretty good about replacing faulty units.
