Homebrew PCBs

I would not want the stuff to be around for more than a week.  I am working in borrowed lab space, and  I don't want to take up too much space.  That being said I am only making boards that are 2x2, and it might take a while to accrue significant(< .5 liter ) amounts of the leftover etchant.  Do you have plans to replenish the used FeCL?
