If you aren't doing this already, try warming the ferric chloride. I use a
double-tank system; one small plastic container of etchant inside a larger
plastic container of hot water. When I'm satisfied with the etching, I just
dip the PCB in the larger container for a rinse. I clean my gloves in there
as well as the small container once I've stored the spent ferric chloride.
I bought that etchant heater from MG Chemicals, a waste of money. The
double-tank system is fast, easy, non-electrical and free (I buy my plastic
containers at the dollar store, so that is as close to free as it gets).
