Trial Purpose:
To evaluate client requested products on the second supplied soil.
Date Run:
07/08/2004Experiment Procedure:
The three cleaners were selected by the client and were diluted to 5% using DI water in 600 ml beakers. All three products were heated to 120 F on a hot plate.
Nine preweighed titanium coupons were coated with client supplied tapping fluid, Master Chemical Corp Trim C270 (102-71-6, 63231-48-1, 141-43-5), using a hand held swab 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 | 0.1628 | 0.0001 | 99.94 |
| 0.1813 | 0.0002 | 99.89 | |
| 0.2526 | 0.0005 | 99.80 | |
| M Aero NS | 0.1688 | 0.0001 | 99.94 |
| 0.2086 | 0.0003 | 99.86 | |
| 0.1696 | 0.0005 | 99.71 | |
| M 400 | 0.1642 | 0.0015 | 99.09 |
| 0.2559 | 0.0015 | 99.41 | |
| 0.1983 | 0.0015 | 99.24 |
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 three products will be tested on the third supplied soil under the same conditions.
