I believe Jeff is right - as long as the detergent is sodium carbonate, it works. I use the Arm & Hammer detergemt because it looks just like a giant version of the old Arm & Hammer baking soda box. That makes it quicker for me to spot in the Walmart aisle where they stock all of their cleaning supplies. I don"t like to be seen frequenting that aisle too long because my wife might think I know something about doing laundry and I sure wouldn"t want her to get that idea! I had the same experience as Jeff with copper - I used copper wire to hook up my sacrificial metal and the process ate that wire into almost within a couple of days. I now try to attach my wire to the sacrifical part outside of the water mixture to keep it from being consumed. I now use stainless steel for the metal because it seems to last forever and is easier to clean off before the next use (currently using side panels salvaged by my son from some sort of commercial kitchen appliance). Regular steel will be consumed quickly if it is thin metal. The bad part of the process (at least in my experience) is that you trade the red dust in your nose for black dust. The process converts the rust into a much softer and inert coating, but I still have to apply the wire wheel to the parts. The difference is that the black stuff is much easier and quicker to remove than the rust coating. I use a dust mask, but I prefer to clean it up outside (upwind!) when I can. I also have found that I can speed up the process and get better results if bad rusted parts are taken out after about two days, remove the crud that has already softened, and then returned to the process for a second run. I"ve used the process on every piece of metal that came off of the to20, including back wheels, brake drums, fenders, hood, front hubs, and bolts and nuts (suspended in a basket made out of hardware cloth). The only rust preventative that I use is a metal prep primer that has phosporic acid in it. It is supposed to help new metal hold the primer paint and also to inhibit rust on metal that has been cleaned of rust. Since any snow will be coming thru your area first, make sure it doesn"t turn into freezing rain - I had 23 days without power several years ago due to an ice storm. Be careful! Larry
