Buy a gallon of ZEP Big Orange, for about $25. It is a concentrated orange cleaner.

Pour some in a spray bottle.
Spritz the sides of the blade every few cuts and you will get shiny smooth cuts with no smearing or burrs.
It is the best cutting fluid I have ever used on aluminum, after 20 years of metal fab experience. Plus it has no water in it so it won't rust anything, and is non-toxic and just smells like oranges.
I use the stuff on my porter Cable 14" dry saw all the time.
