Trial Purpose:
The purpose of this experiment was to determine the effectiveness of Liquinox in removing the white buffing compound from stainless steel coupons via heated immersion with a stir bar.
Date Run:
07/16/2020Experiment Procedure:
Three stainless steel coupons were obtained and weighed. The white buffing compound soil was applied to the bottom third of the coupons with a swab and a soiled weight was recorded. Coupons were then submerged into a 1% concentration solution of Liquinox at 170°F for five minutes. When the five minutes passed, coupons were air dried, and a clean weight was recorded. Effectiveness of the cleaner was determined.
Trial Results:
| Cleaner | Initial wt. of cont. | Final wt. of cont. | % Cont. Removed | %AVG |
| Liquinox | 0.0049 | -0.0009 | 118.37 | 151.92 |
| 0.0034 | -0.002 | 158.82 | ||
| 0.0014 | -0.0011 | 178.57 |
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 Liquinox at a 1% concentration and temperature of 170°F with a stir bar for agitation was effective in removing the white buffing compound from stainless steel coupons. Soil was removed at an average of 151.92%. Percent removals of over 100% indicate that excess soil from previous experiments was also removed from the coupons.
