Rust removal with electricity ( Clean parts the easy way)

I have been cleaning some cast iron pots and pans using electricity and it occurred to me this could be a helpful tool for the folks here on this form.
I ran across some videos on youtube showing the process so I thought I would share one of them here.
This is not my video or me in the video,
There are a bunch of videos out there but this one the guy was cleaning a mower part so I thought it would be a good one to share here.
One thing he does not mention is this process causes an chemical reaction that releases hydrogen gas from the metal ( you will see bubbles coming from the parts) this gas is flammable so if you do this process, do it out side away from any flames etc.
This works for steel and iron ( I am not sure it will work on aluminum )
Thanks and God Bless

i remember seeing that video, i always wanted to try it but i dont have a bucket large enough to try it in

One of the guys on the school bus conversion website that I am also on said that a good vessel for this is an old hot tub. A hot tub would be big enough to do almost anything for a lawnmower, and you can often find non functional hot tubs on craigslist for free.

I'm not seeing where the guy is trying to sell anything on that vid, or in the comments

At any rate, electrolysis is a great way to renovate steel & cast iron parts

You are correct the comment regarding money was regarding sand blasting.

Also, the process works pretty good except in the case of fuel tanks, which are usually so thin that removing the rust leaves a hole behind. I trashed a Vintage XL80 tank that way. Got rid of the rust but left pinholes behind..

POR15 might be a better alternative to electrolysis on the thing stuff. I've done electrolysis a few times and if you don't already know will add a warning. Stay away from stainless steel all together. If you are trying to clean stainless, it doesn't work. If you are using something stainless as the consumable(drawing rust to it) then it produces deadly gasses. Just something to think about. I was trying to clean a buddy's knife and it was so nasty i didn't check to see what type of steel it was, just tossed it in the pot and walked away. The wash soda and water might have cleaned off a little, but that was it.
