Brake discs for electrolysis?
Just before I throw out an old set of brake discs, it did occur to me that they are solid iron. So can they be used for electrolysis as the
sacrificial element?

They may be used but I thin they would be awkward to use.
Several smaller pieces is better
IMHO...

Or bottom of the tub with a draining board plastic mat on top of to give a small gap to the item being cleaned perhaps?

Yep, this was my first thought, large surface area either side of the piece. I believe that while the solution does react all over, there is still a
'line of sight' aspect to the rust removal. So one either side makes sense.
And I can't imagine them wearing out as quick as rebar.

Used a brake disc for my last session. Was v good. Vented helps with surface area also.

All round the item works best. I used some iron bar and bent it in a large coil around the object.

Readily available on eBay, though not overly cheap.

I can find two sources, the best option are graphite gouging electrodes but it seems difficult to get the pure carbon ones rather than the copper
coated ones. And they're not cheap.
The other source is stirring sticks for smelting, although these seem to be pretty much pencils without the wood!

Never thought of these.
Mechanical pencil leads??
