Trial Purpose:
To evaluate successful cleaner from previous trial on second contaminant.
Date Run:
02/27/2002Experiment Procedure:
The Gemtek product was diluted to 10% using DI water in a 600 ml beaker and heated to 130 F on a hot plate. Six preweighed coupons were coated with Mobil Oil Corp Mobilarma 245 (64742-88-7) using a hand held swab. Coupons were weighed again. Three coupons were cleaned for 5 minutes and the other three were cleaned for 10 minutes. Both cleaning utilized stir-bar agitation. Coupons were rinsed in tap water at 120 F for 30 seconds and dried using a Master Appliance heat gun at 500 F for 1 minute. Final weights were measured and efficiencies were calculated for the two cleaning times.
Trial Results:
Both cleaning times resulted in complete removal of the Mobilarma 245. The table lists the efficiencies for both cleaning times.
| Cleaner | Coupon 1 | Coupon 2 | Coupon 3 | Average | Std Dev |
| 5 Minutes | 99.00 | 102.41 | 100.00 | 100.47 | 1.75 |
| 10 Minutes | 104.44 | 102.50 | 102.44 | 103.13 | 1.14 |
Success Rating:
