Electrolysis help??
I enjoy woodworking and collecting old tools and i really would like to restore some pieces I have to like new condition.
My question is this what is the best solution to use and the best amperage/voltage an what are the best materials for the electrodes/ combination
this will be done in either a 5 or 55 gallon bucket

I thank you for the links I know how to do it that way, I was hoping for a more sciency approach to it for example they use sodium carbonate to create
the alkali electrolyte solution but is this the best solution? Or are there others that would be more efficient in there interaction with the iron?
also the voltage I am aware you can use a battery charger but once again is there a specific voltage/amperage that is the most efficient and why is
that volt/amp combo more efficient than others
I am not just wanting to do it but understand the chemistry behind it as well/using the most efficient stuff not necessarily cheapest(dont say platnum
plated electrodes I am not wanting to go that fancy) saying use a tablespoon of Na2CO3 per gallon is not exactly a very sciency way of doing things
nor does it explain how and why that particular solution was chosen for use as opposed to others.

well infact im making some FeCl3 for my dad, and i realised that one piece of the iron electrodes was completely blank
im using diluted 30% HCl (idk.. perhaps its... 5% perhaps less at this process..?)
im using very low current..
ill go check on which of them that was pure blank
they were both very badly corroded before i started as i had some failtastic ideas on how it could be done back in time and mistook it for being 316
steel, but was zinc plated iron.. (:
i just checked and theyre both pretty blank...
meaning both cathode and anode...
thinking about it, its more likely +5% HCl (Muriatic/Hydrochloric acid) solution..
its like a non shiny steel, but yet completely evenly metallic surface.. completely clean, not shiny like freshly cut iron
if you attempt this you might wanna try to stress electrolyse a piece of iron in NaCl, then take the worst piece and try out HCl with your worst
corroded piece of iron, then wash it with water, there after sodium bicarbonate solution (just very weak) and perhaps water again, and perhaps after
that ethanol / methanol / methylated spirits and then wipe off the liquid, so minimum corrosion is made (:
you could try measuring out percentages of HCl and % solution of NaHCO3 if you plan on repeating this more than once, being sure of success every time
