Trial Purpose:
To determine the efficacy of an aqueous cleaner utilizing VCN equipment.
Date Run:
11/18/2023Experiment Procedure:
Three pre weighed brass tubes were used as coupons. The brass tubes were soiled by swabbing the insides with Hycut Et 46 oil. The dirty weights of the tubes were then recorded. The tubes were then subjected to a one-minute heated cycle at 140 degrees F in the VCN using the cleaner Aquanox A4625 at a 1% concentration. The tubes were then removed and left to air dry overnight. The next day the clean weights of the tubes were recorded.
Trial Results:
| Cleaner | soil | Initial wt of cont. | Final wt of cont. | %Cont Removed | % AVG |
| Aquanox A4625 1% | Hycut Et 46 | 1.7422 | 0.0004 | 99.98 | 99.94 |
| 0.8591 | 0.0005 | 99.94 | |||
| 1.1061 | 0.0010 | 99.91 |
Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
Aquanox A4625 1% concentration is an effective cleaner utilizing VCN methods to remove oil from complex brass part.
