Seems like that should work. A bit safer than ferric chloride too...well I guess if you're not etching copper clad, may not be much different (the dissolved copper is what makes that an environmental issue)

Wut? Dude, muriatic acid is WAY more toxic than ferric chloride. I would never etch with that shit unless it's a last ditch effort.
Try Acid Magic and thank me later. Faster, cleaner and won't knock you ought unless you inhale a huge amount.

Acid Magic is awesome. Yes, neutralize with baking soda. Also mix in something like 2 parts AM to 1 part high test hydrogen peroxide (from a beauty supply store) and it will work much faster. Just keep a really good eye on it, wear rubber gloves, don't inhale the fumes that are produced.
