If your Eclipse is a CS (gravity feed), one easy thing to do during basic flushing is to fill the cup with your flushing fluid, then stick a pipette down into the cup so the tip is right on top of the hole where the needle goes back into the body, and pump the pipette several times. This blasts the cleaning fluid back and forth directly across the needle channel opening in a way that cycles fluid through the needle channel between the cup and the packing via Venturi effect.
This flushes out a lot of stuff from that channel that would otherwise be untouched by anything other than a tear down cleaning. Try it after you've already flushed the cup and nozzle 'till they seem clean, and you'll be surprised how much color comes swirling back into the cup from the needle channel.
