OK - well it's time to have a look through your tools etc and
see if anything is rusty and needs a good rust treatment. 

Do you have a 12V power supply?
Mine was drawing about 2 amps.

Yes - always keep tools well oiled.

Actually - electrolysis will damage the edge of any sharp tools
such as chisels, scissors or knives so
it can still be done but then you have a major re-sharpening job to do.

yes - any product that forms an acid will work well.

A further interesting note - copper plating.

Use about a cup full of Aluminium Sulphate for every 2 litres of water
always in a plastic container. Have good ventilation due to Hydrogen gas.

You can also use the same method for copper plating the item you have cleaned of rust.

The formally rusted item is connected always to the 12V negative electrode and
the positive 12V to the sacrificial electrode - just some steel strips.

Also - to the negative electrode attach copper wire in the solution of Aluminium Sulphate -
use multi-stranded wire.
That copper wire will dissolve in the solution in about 20 minutes creating copper ions
that will copper plate the item that is also negative.
It won't be flaky copper plate that will rub off but -  high quality thick copper plating!
That will form a nice surface as for a finished item or it can also be painted over.
Note - only shiny clean areas will be copper plated.


So - where can you buy your Aluminium Sulphate from?

https://www.bunnings.com.au/hy-clor-2kg-flocculent-soft-pack_p3090210

$20.85 for 2 kg.

Normal usage:
High potency granular flocculent for muddy, algae infested or severely cloudy pools.
For use in pools where the floor of the pool can no longer
be seen due to suspended particles or algae in the water.

Always use safety goggles.

Several tests in this video demonstrate the strengths and weaknesses
of various store brand rust removal products
(CLR, Krud Kutter, Evap-Rust, Loctite Naval Jelly), Muriatic Acid,
as well as other options such as using vinegar or Coca Cola.
More product details at the very bottom of the description.
Which one works the best? 
After conducting the tests, I like Krud Cutter the best.
However, other products, such as Evapo-Rust proved to be very effective as well.
Loctite Naval Jelly would be my pick for a flat metal surface.
