[HH] rust removal

[Mark Woodward]

I used to do a lot of car work. I had a modified classic firebird. You 
would get hard to find parts at the bone yard and remove the rust 
easily. The thing that I would use is sodium perchlorate (oxy-clean) 
dissolved in water and a battery charger for electrolytic rust removal. 
It was amazing, connect the electrodes, drop a part into a bucket of 
solution, and in a day, the rust was gone. You can google for the exact 
ratios and stuff.

I imagine you could construct a recirculating continuous stream system 
with a water pump and a tray big enough to catch the return solution for 
objects bigger than can be easily submerged.
