Trial Purpose:
To evaluate client requested products on the fifth soil.
Date Run:
07/08/2004Experiment Procedure:
The three cleaners were diluted to 5% using DI water in 600 ml beakers and heated to 120 F on a hot plate.
Nine preweighed titanium coupons were coated with client supplied Wolverine Ultra Flux (1332-77-0, 10043-35-3, 7789-29-9, 11128-29-3, 151-21-3), using a hand held swab and then heated with a Master Appliance Heat Gun at 500 F for 10 minutes. Coupons were allowed to cool and then weighed a second time to determine the amount of soil added. Three coupons were cleaned in each solution for 5 minutes using stir-bar agitation. Coupons were rinsed in tap water for 15 seconds at 120 F, followed by air blow off at room temperature. Once dry, coupons were weighed a final time and efficiencies for each cleaner were calculated.
Trial Results:
All three products removed over 99% of the second oil. The table below lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
| Cleaner | Initial wt | Final wt | % Removed |
| M Aero | 1.1170 | 0.0014 | 99.87 |
| 1.2380 | 0.0004 | 99.97 | |
| 0.8871 | 0.0069 | 99.22 | |
| M Aero NS | 0.9014 | 0.0039 | 99.57 |
| 1.3230 | 0.0009 | 99.93 | |
| 1.2541 | 0.0001 | 99.99 | |
| M 400 | 0.7871 | 0.0013 | 99.83 |
| 0.9139 | 0.0038 | 99.58 | |
| 0.8060 | 0.0035 | 99.57 |
Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
The supplied products will be tested on the sixth supplied soil using manual wiping at room temperature.
