Trial Number 9

Trial Purpose:

The purpose of this experiment was to confirm removal results from Trial #8.

Date Run:

09/14/2020

Experiment Procedure:

Three general steel TURI coupons were obtained for each of the four cleaners tested. The cleaners were prepared to the following conditions: Metalnox 6386 100% concentration room temperature, Mirachem 500 20% concentration 110°F, SC Aircraft & Metal Cleaner 20% concentration 130°F, and Shopmaster LPH 20% concentration 130°F. An initial weight was recorded for each coupon, then coupons were soiled with the Vanishing Oil provided by the company. A soiled weight was recorded and coupons were then submerged into their respective cleaners for 15 minutes. After 15 minutes had passed, cleaners were submerged into a deionized water bath at 115°F for 20 seconds. Coupons were then dried using the hot air gun and a cleaned weight was obtained. Effectiveness of cleaners was then determined.

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion:

Shopmaster LPH was the most effective cleaner removing an average of 106.71% of soil from the steel coupons. Mirachem 500 was the second most effective removing an average of 100.85%, and Metalnox 6386 was the third most effective removing an average of 92.87. The next steps would be to test on company steel coupons.
