Cleaners were prepared to the following concentrations: Dimethyl glutarate 100%, Smart Solve 605 100%, SC Aircraft & Metal Cleaner 20%, SC Supersolve 20%, Crystal Simple Green Industrial Cleaner 30 parts water. All cleaners, except for Crystal Simple Green, were heated to a temperature of 120°F. Crystal Simple Green was kept at 100°F as the cleaner cannot be used above 105°F. A stir bar was added to the Crystal Simple Green solution for agitation. Three stainless steel coupons were obtained and weighed for each of the cleaners being tested. Coupons were then soiled with grind oil provided by the company and a dirty weight was recorded. Once solutions reached the proper temperature, coupons were submerged into their respective cleaners for 15 minutes. After 15 minutes, coupons cleaned with SC Aircraft and Smart Solve 605 were submerged into a deionized water bath at 120°F for 30 seconds. All coupons were partially dried with a heat gun and allowed to finish drying in air. A clean weight was recorded and effectiveness of the cleaners was determined.
