Rust removal by Electrolysis – Removing rust from a Briggs and Stratton engine shroud



A demonstration of removing rust with electricity.

This is not recommended for brass, aluminum, copper or exotic metals and alloys.

Electrolysis is a method of removing iron oxide (rust) by passing a small electrical charge from a battery or battery charger through the rusty metal to stimulate an exchange of ions while the rusty metal is submerged in an electrolyte solution.

  1. Plus you can get ten feet of iron pipe for 60 bucks cut it in 4 2.5 ft sticks and use a Rubbermaid commercial trash can. They also have the wheel setup which is pretty neat to roll your project around and also get it out of the garage to dump it it will be heavy. Plus you can put the lid on for safety.

  2. Hi mate can you explain what the ingredients in the washing soda is? Pretty sure we cannot get that here in NZ but we might have something close.

  3. Great video! I took a Craftsman yard cart and lined it with a new gray tarp from HF. I de-rusted all the parts from an old Walker Turner 16" Bandsaw in this. The main frame came out perfect. I also re-did the doors on the bandsaw after I decided I didn't like the color I painted them. They had dried for a few days too, but the electrolysis stripped all the new paint right off. I'm gonna do an old heavy cow bell today that I found in the woods with a metal detector (Whites XLT). If you have rusted items to strip down, you gotta try this! Thanks for making this video.

  4. Your video inspired me to try it and make a video of my results. It really does work! It took all the rust and most of the paint off my old scooter and some engine parts.

  5. When you scrubbed it down in your wife's kitchen sink did you imagine what your next wife will look like? 🤔
    Seems like one of those commercials……"Bleach cleaning up life's little messes!"
    Great video though I'll be trying this soon! I have a mystery item I'm trying to clean enough to see better!

  6. Will the trickle chatger work? If you have to use batt charger, what amps do you set it to? Should it be on slow charge or boost/engine start?

  7. It's nice to see someone using the CORRECT way of connecting the leads, I've seen so many IDIOTS use the wrong way and end up wondering why it hasn't worked as well as those using the correct way of connecting the terminals…..
    Tim Fox messaged you saying, "Electrolosis is line of sight", … YET ANOTHER IDIOT who knows NOT what he is talking about.
    For the BEST RESULTS, … use 4 pieces of sacrificial steel rod, (ie: big old bolts, re-bar, flat bar steel, ect, and place them in each corner of your square/oblong PLASTIC tub, then, connect all 4 pieces together with electrical wire ABOVE the water line, sand or scrape or grind the area where you attach the wire and twist it tight, and suspend your rusty part in the middle and make a clean connection to that too.
