Trial Purpose:
Laboratory evaluations of alternative cleaning products
Date Run:
05/27/2004Experiment Procedure:
Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning.
Each product was used at full strength in a 250 ml beaker and heated to 96 F on a hot plate. Nine preweighed silver plated copper coupons were coated with the Lanson Oil Co Vanish 6912 (6742-48-9) using a handheld swab. Coupons were weighed a second time to determine the amount of soil added to each coupon. Three coupons were cleaned in each solution for 5 minutes using stir-bar agitation. After cleaning parts were weighed a final time and efficiencies were calculated.
Trial Results:
| Cleaner | Initial wt | Final wt | % Removed |
| Vertrel MCA | 0.1071 | 0.0074 | 93.09 |
| 0.0366 | 0.0055 | 84.97 | |
| 0.0661 | 0.0124 | 81.24 | |
| Heavy Duty Degreaser C | 0.0682 | 0.0036 | 94.72 |
| 0.0364 | 0.0072 | 80.22 | |
| 0.0731 | 0.0064 | 91.24 | |
| Flux Remover C | 0.0357 | 0.0156 | 56.30 |
| 0.0504 | 0.0140 | 72.22 | |
| 0.0766 | 0.0098 | 87.21 |
Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.Conclusion:
Two of the three removed over 85%.
