The old tool group I used to read more was very into electrolysis (and it certainly worked far better than anything I'd ever used before) but got a bit leery due to hydrogen embrittlement (which can be mitigated, and is mostly of concern with hardened and high-carbon steel, so edge tools, mostly) and moved on to citric acid being more popular - in either case you need to rinse well and dry the item quickly or rust will start right back up. Mitigating the hydrogen is primarily a matter of extending heating to dry for a while longer than it takes to just dry, without going so hot as to ruin the temper. A purported advantage of citric acid is that it is unlikely to eat good steel in any reasonable time, but does effectively remove rust. Electrolysis really does just eat the rust and leave the steel alone, but it may not be kind to plating.
My proof of concept tool for electrolysis was a pair of pliers I picked off the side of the road one spring. I live where there is winter, and the roads are salted in winter. This pair of pliers was solidly frozen, immobile, heavily rusted. After a while (12 hours? more?, I don't recall) in the tank, they moved freely - very freely, as a good part of the pivot pin had turned to rust, and bulk rust ends up in solution when removed electrolytically. So they are not great pliers, but they are far better than the junk they were as found, and I would never have gotten there with naval jelly, in my experience of naval jelly (lots, all disappointing.)
