Trial Purpose:
To determine the efficacy of modified alcohol Metalnox M6386 chemistry in removing various industrial soils without the assistance of vacuum vapor degreasing equipment.
Date Run:
08/10/2026Experiment Procedure:
Three Aluminum coupons were assigned to each of 2 industrial soils; Hocut 759 oil and Phillips Multiplex FS 220 Grease. Each coupon was weighed using a gravimetric balance and had their initial weights recorded. Each coupon was then soiled with a pea sized amount of the appropriate soil using a swab to spread it across the surface of the coupons. Each coupon was weighed again and had their dirty weights recorded. The coupons were then immersed in a beaker of the Metalnox M6386 modified alcohol with a stir bar set to 100rpm for 5 minutes. Upon removal from the beaker, the coupons were allowed to air dry for 20 minutes before being weighed and having their final weights recorded.
Trial Results:
| Soil | Initial wt of cont. | Final wt of cont. | %Cont Removed | % AVG |
| Hocut 795 | 0.2070 | 0.0138 | 93.33 | 94.27 |
| 0.2093 | 0.0134 | 93.60 | ||
| 0.2007 | 0.0083 | 95.86 | ||
| Multiplex FS 220 | 0.2041 | 0.1853 | 9.21 | 10.84 |
| 0.1951 | 0.1721 | 11.79 | ||
| 0.1981 | 0.1753 | 11.51 |
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 Metalnox M6386 modified alcohol was successful in removing the Hocut 795 oil but was unsuccessful in removing the Multiplex FS 220 Grease.
