I found this out on youtube today, and thought I'd give it a try. The ingredients for the etching solution are White Vinegar, Hydrogen Peroxide (I used a 6% from the drug store) and Salt. It takes a while, but it gave GREAT RESULTS. Here's a pic of an arduino controlled (stand alone) main board for a pickup winder I'm building again (Just moved out of country).

I found that if you have alot of copper, it takes a LONG TIME. But, if you have a circuit design with a ground plan, i.e., not much copper to etch, it will work pretty darned fast. You have to keep wiping the "residue" off the top, but if your scared of dealing with Ferric Chloride (STAIN), or Muriatic acid, then this is the way to go.

Thanks to the OP. Useful stuff

I am assuming those who are drawn to this will know the answer to my question which is .

Using Eagle free how can I make it leave as much copper on the board as possible?
