Four lab selected and one client supplied cleaner were diluted to 5% using DI water in 600 ml beakers. Each solution was heated to 130 F in a Crest 40 kHz ultrasonic tank and degassed for 5 minutes prior to cleaning parts. Two parts were cleaned in each solution, one part at a time, for 10 minutes. Following the cleaning, the parts were rinsed in a tap water bath at 120 F for 15 seconds and then dried using a Master Appliance Heat gun at 500 F for 1 minute. Parts were observed visually and wiped with a white swab to determine level of cleanliness.

Contaminant: Fuchs Renocut 127 (mineral oil)

All of the parts cleaned looked very clean, with no visible signs of oil anywhere. The cleanliness of the parts was nearly identical for all of the cleaners evaluated. The large lamp parts had some water spots that developed during the drying process. The following table lists the observations for each part cleaned.

Table 1. Observations

All products tested were very effective in cleaning the supplied parts.
