Trial Purpose:
To evaluate client requested products on the third supplied soil.
Date Run:
07/08/2004Experiment Procedure:
The three cleaners were diluted to 5% using DI water in 600 ml beakers. All six products were heated to 120 F on a hot plate.
Nine preweighed titanium coupons were coated with client supplied oil, Exxon Mobil DTE Light, 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:
Two of the three products removed over 85%. The third product removed just under the 85%. 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 | 0.2715 | 0.0000 | 100.00 |
| 0.2305 | 0.0010 | 99.57 | |
| 0.3331 | 0.0014 | 99.58 | |
| M Aero NS | 0.1425 | 0.0006 | 99.58 |
| 0.2562 | 0.0015 | 99.41 | |
| 0.3962 | 0.0002 | 99.95 | |
| M 400 | 0.2000 | 0.0478 | 76.10 |
| 0.3585 | 0.0390 | 89.12 | |
| 0.2555 | 0.0279 | 89.08 |
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 requested products will be tested on the fourth supplied soil under the same conditions.
