What electrolyte are you waiting for? All you need is some bicarbonate of soda.
The other thing to try if you’re not in a hurry is white vinegar; it is very cheap (<£20 for 20L on EBay) and avoids all the hassle of fashioning electrodes shaped to reach the deeper recesses of the tank. The one advantage of electrolysis is that it only attacks the rust, not the good metal underneath.
Just pour the vinegar in and leave for a few days – depending on the degree of rusting – pour it out, but not down the drain. If you’re not happy just pour the vinegar back in and wait some more. If there is a lot of deposit in teh vinegar you can strain it using a kitchen sieve.

You can also use Citric Acid (available everywhere and as cheap as chips). It is the main ingredient in Deox-C. We have used Citric Acid with excellent results.

Electrolyte works well but can be fiddly fashioning an electrode and an insulator, currently being discussed on another thread... Recently i have used “evaporust†to good effect. Pro’s its re-usable and can be used on any ferrous items.. con’s its a bit expensive at 30 odd quid for 5 litres.... magic stuff though, not acidic at all....works by breaking the iron - oxygen bond, clever stuff.

In reality I guess the Citric Acid is just there to produce ions to allow the current to flow so many alternatives can work. Obviously not Table Salt as that would give off Chlorine gas as opposed to Hydrogen at the Electrode (Anode end ?).

I bought some white vinegar a few weeks ago with a view to trying it - then read loads of reviews saying it does not work! We having it on our Fish & Chips instead. lol
