Well, you got me there.
I did a search for the hercules stick and the spec sheet says
Trisodium Phosphate one of the ingredients. I wonder how much it
costs.
I've never seen it in Australia. HCl and scrap copper are so
cheap and widely available, so if you cannot buy the patented
Hercules Flip Sticks then the copper oxidizing in the tray method
is probably worth a shot.
