How do I tell if my parts are clean?

There are many tests to determine cleanliness. The most widely used is the "water break free" test. This test is a visual observation of whether water fully sheets over the clean part or draws away from portions of the surface (like water on a waxed car). Other tests may include wiping with a white cloth, alcohol drop tests, or other more sophisticated laboratory testing like coulometry (organic soil is burned off the substrate and measured). Again, your pretreatment supplier can assist with evaluating your part cleanliness.
