Trial Purpose:
To evaluate client requested products on fourth supplied soil.
Date Run:
07/08/2004Experiment Procedure:
The three cleaners 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 peanut oil, 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 90% of the peanut 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 | 0.0710 | 0.0035 | 95.07 |
| 0.2036 | 0.0039 | 98.08 | |
| 0.2429 | 0.0074 | 96.95 | |
| M Aero NS | 0.1218 | 0.0155 | 87.27 |
| 0.2523 | 0.0021 | 99.17 | |
| 0.3703 | 0.0047 | 98.73 | |
| M 400 | 0.1484 | 0.0158 | 89.35 |
| 0.2335 | 0.0242 | 89.64 | |
| 0.2832 | 0.0197 | 93.04 |
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 used on the fifth supplied soil under the same conditions.
