As a long term ferric chloride user, I came across this interesting 'Instructables' article, so decided to try it out.
It definitely makes a improvement to the etching time, with the downside being that the user is working with dangerous corrosive acid (Muriatic, aka Hydrochloric acid), as in Pool Acid.
what surprised me is the mention of Ferric Chloride being so hazardous.
I for many years, I've often just lifted a pcb out of the solution by hand, rinsing the paws immedialtely under running tap water without burns, etc.
The worst effect is a slight brown stain on the skin, and of course, it stains clothing brown.
Googling it, it is a midly acidic etchant, poisonous if ingested, but may irritate sensitive skin.
Thought the 'Instructable' link may be of interest to the 'etchanter' community...
