As we clean up wood stain from brushes and equipment it contaminates the paint thinner used in the parts washer.  The good news is that most of the stain settles to the bottom.

Here is a “funnel” that we designed and had fabricated by Anything Metal in Altoona.  It will allow the solids to flow to the bottom overnight, and then we can draw them off and properly dispose of, while dramatically reducing the amount of paint thinner we need to dispose of.
