parts washer solvent

[jniolon@uss.com]

     been following the thread on solvents for parts washers
     
     I've got a "tabletop" washer (SafetyKleen) that has the sink mounted 
     on top of a plastic container that probably holds 5-10 gallons.  I've 
     got a new can of super Agitene under my desk right now and asap will 
     swap out the  "SafetyKleen" solution for the Agitene..
     
     Would it be advantegous to install some type of filter system (if 
     possible) to preserve the Agitene as long as possible..or would it be 
     a waste of time and material for the benefits .
