Default electrolysis question

I have used electrolysis to clean a couple of old axe heads. I used a single scrap piece of steel as my positive and clipped the negative on my relic. all worked well.

I am trying to decrease the electrolysis time by putting four pieces of aluminum at North, south, east and west on my bucket for my positive.

will aluminum work or does it have to be iron or steel for your positive?

Aluminum will conduct electricity, but using iron or steel will be quite a bit more efficient.

Stick with iron for better results. I use a metal bucket 99% of the time when I run my tank. If you suspend your item in the bucket, you get the electricity moving all around. I just get the $5 painters metal buckets at home depot.

Stainless steel and powdered dishwasher soap added to the water will help speed up the process. Once I ran out of scrap stainless, I just bought a couple stainless steel bolts at the hardware store. Works great !!

I use these carbon anodes, and they work great.

I have tried scrap metal, steel, nails. I have found these anodes to be the best solution for my electrolysis cleaning.

hot/warm salt water. The higher the salt content the more conductive the water is. You basically dump a bag of salt onto your item while its sitting in the water... not sure what you are cleaning though so might want to think about what salt will do to it (works great for silver)

Steve; While you're correct that salt will increase the conductivity of the water, it will also act corrosively on the metal object you're trying to save, and will have bad effects on the power supply. If one is using just a charger, (especially a small one), it'll burn out in short order due to higher-than-designed current demands by the salted fluid.
From what info I've dug up, one should use an automotive battery charger, in the 6-10 amp range. Get everything set up, check the current output on the charger's gauge, then start adding washing soda to the water until you get to about 80 or 90% of charger's rated current output.
Check your "save" often until it's as clean as you think it'll get.
(Safety note: do this in a well ventilated environment. The electrolysis action can give off toxic gasses that you really don't want in your lungs.)

i just use it for some small silver on occasion using old cell chargers. Afterwards I wash it and buff it up with silver polish. Good as new or at least good enough that my scrap guy will take it.

He is correct. ARM AND HAMMER WASHING SODA is what I use. Stainless steel is supposedly releasing a poisonous gas so use iron.

I take a storage bin and secure my sacrificial anodes in each corner then connect them with copper wire. I use 2 car chargers and occasionally 4. I use railroad plates and when they slow down or stop because of their accumulated rust, I take a belt sander and remove the rust and continue to use them

Is washing soda the same as baking soda?

Not the same but I have never seen a difference in the final results.

A reminder (just to state the obvious).
If you find something of value, monetary or historically which you may wish to
sell, do nothing to it. By cleaning (other than washing in water) you could
seriously affect it's value.
