Homebrew PCBs

I am trying to etch a small pcboard made using toner transfer. 
Am applying FeCl with a sponge by hand. Never completes etching, after many hours, result is only partially etched.  Also immersed pcb in bowl of FeCl. Results are the same. 

My FeCl from RADIOSHACK (GL brand) is very old and has  been sitting on shelf unused for years. I have a 3/4 full container I would like to  restore.  I need to know what are the methods and chemicals needed to restore my old FeCl to etch quickly and completely.  

FeCl color is dark brown or black with a green tint.
Container has a mix of dark brown and green liquids. 

The restore etchant info in the archives has me confused.

At Photobucket, I have  some pictures.
