Trial Number 1

Trial Purpose:

To test the effectiveness of EnvirOx Storm against Green Works AP.

Date Run:


Experiment Procedure:

Two different types of soils were prepared. The first soil, maintenance soil, consisted of 10 g carbon black, 10 g iron oxide, 100 ml WD-40, 100 ml hydraulic oil, and 100 ml gear oil. Each component was placed in a 750 ml beaker and mixed for 20 minutes at room temperature with a magnetic stirrer. The second soil, production soil, was made by mixing 200 ml Quench oil and 200 ml cutting oil for 20 minutes at room temperature using a magnetic stirrer.

Approximately 100 mg of each soil was applied to a pre-weighed and pre-cleaned stainless steel coupon onto one side only with use of a hand swab. The maintenance soil for the first set of coupons was baked in an oven for 30 minutes at a temperature of 40° C (105° F). For the production soil, the second set of coupons was baked in an oven for 30 minutes at 105° C (220 ° F). The coupons were then allowed to cool to room temperature and weighed a second time and recorded as dry weights.

All products were used a room temperature. Beakers were filled with enough fresh cleaner solution to completely submerge the contaminated portion of the coupons. Each coupon was placed in a beaker, and were washed for 30 minutes using un-heated immersion cleaning only. The washing was followed by a rinse using tap water for 30 seconds. After the rinse, all coupons were air dried for 60 minutes and then placed in an oven to dry at 105° C for 30 minutes. The coupons were allowed to cool to room temperature and final weights were recorded.

Success Rating:

Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.


EnvirOx Storm was effective in the removal of both containments, and preformed significantly better in comparison with Green Works AP in the maintenance soil removal.
