WebJul 30, 2009 · Electrolysis will work on any oxidized metal, iron, brass, aluminum. The secret is how it is done. If you put aluminum into a strong basic solution such as is typically recommended then you better be ready to pull out the aluminum in a few seconds. If you use baking soda as an electrolyte and limited current, around 1 amp, it will work just fine. streetlink referral number
