Cadmium	CGAL	OpenCSG, showing artefacts

Method	Advantages	Disadvantages
Ferric chloride	Etches at room temperature.	Horrid yellowy-brown colour stains everything it comes in contact with. Best done outside using things you'll never use again.
Ammonium persulphate	Does not stain. Easy to tell how much copper the solution contains, and therefore whether the solution is still ok.	Only etches at 60-70ºC and above. Can be a bit fiddly to get the right concentration.
HCl/H₂O₂	Can be recharged by bubbling air through it with an aquarium pump, which means less chemicals to buy, and less to dispose of.	Two rather nasty corrosive chemicals, so care must be taken.
