Trial Purpose:
To test the effectiveness of Surface Cleanse 930 on the removal of various contaminants.
Date Run:
08/14/2020Experiment Procedure:
Three sets of three pre-weighted aluminum coupons were soiled with their respective contaminants using a cotton swab. Each set of coupons were immersed into a beaker with Surface Cleanse 930 at a concentration of 5%, for 15 minutes at a temperature of 120° F. During this process, any noticeable soil removal was observed. Coupons were dried with a heat gun as well as with a manual wipe afterwards, to inhibit the cleaner creating visual damage to the substrates. After drying, final weights were recorded, and efficiency was calculated for each coupon cleaned.
Trial Results:
| Cleaner | Soil | Coupon | Initial wt. of cont. | Final wt. cont. | % Cont. Removed | Average |
| Surface Cleanse 930 (5%) | Red | 8 | 0.0129 | 0.0025 | 80.62 | 83.93 |

| White | 19 | 0.0147 | 0.0028 | 80.95 | 82.51 | |

| 22 | 0.0472 | 0.0062 | 86.86 |
Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.Conclusion:
Visually Surface Cleanse 930 did not generate much removal but did preform gravimetrically very similarly for all three soils. The subsequent step is to keep the time and temperature constant and introduce agitation in the form of ultrasonics.
