Rust removal by electrolysis
I saw some vids on youtube re rust removal with a battery charger. I would like to give this a job but on a slightly larger scale - i.e an old 6 cyl engine block. Has anyone on here given it a go before? Will I need two battery chargers for a larger piece or will one do it? Instead of using a battery charger (I don't know if mine is suitable) could I use a 12 or 24v power supply instead? Where would I be able to buy one of these? A quick search of youtube only yielded PC power supply units which didn't look suitable.
