Examination of Cleaning Materials, Techniques, and Evaluation Processes on Various Material Surfaces

Solvent cleaning, baking, acid immersion, and hydrogen peroxide immersion cleaning techniques were tried on glass, ceramic, metal, and plastic surfaces. Test results showed that detergent cleaning using 1% detergent solution in distilled water with ultrasonic agitation is the most effective and/or practical technique for removing organic and silicone thin film contamination from such surfaces.

Evaluation of cleaned surfaces by water-break technique is sufficiently critical to detect contamination buildup on polished surfaces after 20 minute exposure to air.
