Hi, following is a note I sent last week to my other passion, 1916-29 Hudson cars. I first heard about this on this forum. I then googled "rust+removal+electrolysis" and found a wealth of good information. Hope this helps Have any of you folks tried this? I have been using it on body parts of my 23 with what I consider amazing results. Inexpensive and safe. I wish I had discovered it years ago. You need the following: a plastic container, some scrap steel, washing soda (eg Arm and Hammer) and a battery charger. You arrange the scrap steel around the sides and bottom of the plastic container and make sure that they are all electrically bonded to each other. This is your anode and gets hooked to the positive terminal of the battery charger. Connections should be rust free at the points of connection. Fill the container with water and add 1 tablespoon of washing soda (baking soda will also work) per gallon of water. Suspend the part to be cleaned (the cathode) so that it cannot touch the surrounding scrap. Hook the negative to the part to be cleaned and turn on the power. You will soon see small bubbles form on your part and the scrap. this will eventually turn into a rusty foam blanket. After a few hours, say 12 to 24, turn off the charger and lift out your part. Use either a small pressure washer of a Scotchbrite pad and the rust and old paint pretty much just falls off, leaving clean metal. Action is "line of sight" so you may have to do some careful positioning of the anode bits so that they are located inside a cavity or bend you are trying to clean The beauty of this is that it is non toxic, consumes very little energy and will only attack the rust, not the parent metal. Do not use on aluminum and other alloys. Make sure that you have the polarity right, positive on your scrap, negative on your part, otherwise your part could be eaten away. I am using a 6 amp, 12 volt charger. I can send more info and some pictures if anyone is interested. Maybe this is all old hat for you but I am excited by the results. Karl
