The silicon oil was smeared on the five polycarbonate parts and allowed to age for two hours. Cleaning was performed in a Crest Ultrasonic Unit for 15 minutes set at 140 F. The parts were rinsed in a tap water bath and then a DI water bath. Both rinses were for 5 minutes at 140 F. The parts were then dried under air knives for two minutes and then under and IR lamp for 30 minutes. The parts were then analyzed under a black light for fluorescence and visually inspected for any water spotting.

Silicon Oil (WD40), fingerprints
Visually, the parts were very clean. Upon inspection under black light, part #5 had two areas of oil on it. No water spotting was evident on the parts.
The Valtron cleaners was basically successful. A longer cleaning time and additional rinses should solve the problem of the oil remaining on part #5.
