Trial Purpose:
To evaluate selected cleaners on supplied parts using immersion cleaning followed by spray cleaning.
Date Run:
11/07/2006Experiment Procedure:
Two cleaning products were diluted to 5% using hot tap water (130 F) in 1000 ml beakers. Supplied parts that were received already contaminated were cleaned in the immersion solution for two minutes and then cleaned in the spray system for one minute. Two types of parts were cleaned in each solution. Following cleaning in the low-pressure spray system parts were rinsed for 15 seconds in a tap water bath at 120 F and dried using dry compressed air at room temperature. Parts were analyzed visually. Cleaned parts were packaged and sent to the client.
Trial Results:
| Cleaner | Part | Observation |
| Polyspray Jet | Angel with harp | Removal of contaminant evident in cleaning solution |
| Santa Clause | ||
| Detergent 8 | Angel with harp | Removal of contaminant evident in cleaning solution |
| Mrs. Clause |
Success Rating:
Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.Conclusion:
Both solutions at the lower concentration appeared to remove the buffing compound using 2 minutes of immersion and 1 minute of spray cleaning. Parts have been sent back for client inspection.
