Trial Purpose:
Laboratory evaluations of alternative cleaning products
Date Run:
05/26/2004Experiment Procedure:
Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning.
The three products were used heated to 96 F on a hot plate in 250 ml beakers. Nine preweighed steel coupons were coated with Castrol Quench G oil (64742-55-8, 64742-65-0, 8052-42-4) using a handheld swab. The quench oil was then heated with a Master Appliance Heat gun at 300 F for 10 minutes. After cooling to room temperature, a second weighing was performed to determine the amount of soil that was added. Three coupons were cleaned in each solution for 5 minutes with minimal stir-bar agitation. After drying, coupons were weighed a final time to determine the cleaning efficiency of each product.
Trial Results:
| Cleaner | Initial wt | Final wt | % Removed |
| OS 10 | 0.2443 | 0.0040 | 98.36 |
| 0.1599 | 0.0040 | 97.5 | |
| 0.1475 | 0.0010 | 99.32 | |
| OS 20 | 0.2311 | 0.0027 | 98.83 |
| 0.2689 | 0.0019 | 99.29 | |
| 0.2325 | 0.0031 | 98.67 | |
| OS 30 | 0.1503 | 0.0110 | 92.68 |
| 0.2196 | 0.0077 | 96.49 | |
| 0.1436 | 0.0076 | 94.71 |
Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.Conclusion:
The three products removed over 85%.
