Yes, forgot to say I do that too. I gave up on making an etchant system
with automated rocking, air agitation, heating and wide screen TV; just not
worth the hassle. I use ordinary kitchen gloves and rub the PCB 'lightly'
using a green scrub pad. This is a thin sheet of nylon mesh, not abrasive,
it's just to remove spent etchant and copper deposit from the PCB surface,
nothing more.
Under 10 minutes as well.
