WOW!

That is awesome. I will be building my setup in the near future.

Thanks, Fritzhund

thats a very good tip to remember, very cool

I thought it was common knowledge with all the threads about electrolysis on this forum.
It works well, is cheap and very easy.

So my question is this: if electrolysis is performed on a chrome or zinc plated part, will the electrolysis process remove the metal plate? Seems to me it would, which means electrolysis should be limited to parts that are not plated. For chrome, Evapo-Rust or oxylic acid seems safer.

It does not hurt good chrome, but where the chrome is pitted the same black stuff that forms on the bare metal forms downstream where the bubbles come out of each pit. The key is to use very low current on chrome. I think changing the water more often helps keep it clean too. I have only done very few chrome things, as nothing really rusts around here.

I would bet that the electrolosis will turn the impurities within the chrome black, which will look "speckled". I definately would not do this on anything chrome (at the least, not on a nice chrome finish)

It's the pits from rusting, not the impurities. You can see each pit making a stream of bubbles, and they leave a trail of black. Turn the current down and it's not a problem.
Seems to me a nice chrome finish would not be rusted?
It works best on bare steel, or steel where the paint has failed.

Here's a before and after shot from a year or so ago:

That is amazing!!

Now, where can I find a tank of water that is big enough for that Toyota pickup of mine...

That sounds suspiciously like the voice of experience...

I've been doing this for years. You have to be carefull of a couple things. The electrolosis creates oxygen, hydrogen, and some other not-so-good gases. Be sure to do it in an open area and not near flames. Yes, it will take a long time to get enough to cause an issue but it could still happen. Also, if you use a stainless steel electrode it will not break down as quickly or become as full of crud. BUT, it will also release some nasty, nasty gases from the stainless breakdown. Do it in a place where you can leave it and not be exposed to the resulting gases. Be sure to not leave the part in too long as it will eventually attack the good metal and create some pitting that wasn't there before (left a part in overnight accidentally once). It's a great process though and comes in really handy.

can't find any video about chrome or rust removal...

can someone post the link please ? I would like to paint the chrome
parts and remove the chrome for that purpose...
