I have these two pieces of metal which I intend to use as a frame for a machine that I am building and and I wanted to use the electrolysis method of removing the main part of the rust so that I don't have to spend hours and hours doing it with a grinder or a wire brush.
The two metal parts have been out in the rain for 3 to 4 years so they are very rusty so it will probably take a couple more goes and kill we are ready to finish them off.
I used a power metre so that you can get a good idea of how much electricity the whole process uses.
I used about 100 g of sodium bicarbonate in about 15 l of water I will try standard table salt as well because I can get this much cheaper.
I only got 3 hours as I started at lunchtime, when we get some more sun I will be on it again !
Plus I am very interested in using alternative energy sources for doing stuff like this.
