Yes, PLEASE do not dump used etchant down the toilet! Very nasty stuff, even
when neutralized. Take used etchant to one of the hazardous waste disposal
sites , there are at least three in King County: Factoria, North Seattle and
South Seattle (http://www.govlink.org/hazwaste/house/disposal/othersites)
for hobby-quantity waste. There is no disposal fee either!

Use a synthetic sponge for this.

Or use the "etch in a bag" to keep the amount of etchant to a minimum.

You should also be careful about dumping etchant into the swerage  
system ... at the very least you should neutralize it with a base. If  
you are doing large amounts dispose of the copper-loaded FeCl3 waste  
responsibly. It's nasty to wild life (i.e. fish!).
