Preliminary testing of potential alternative cleaners to determine efficacy in removing buffing compound and castor oil.
Date Run:
06/10/2024
Experiment Procedure:
Three pe-weighed coupons were chosen per soil per cleaner were used for a total of eighteen coupons. Half the coupons were soiled with tripoli buffing compound by holding the buffing compound over a heat gun until it was melted enough to spread on the bottom third of each coupon. The other half of coupons were soiled with castor oil by applying the oil to the bottom third of the coupons with a swab. The dirty weights of the coupons were then recorded. Each coupon was subjected to heated ultrasonics for 20 mins in their respective cleaner. These cleaners are Micro 90 2% 150F, Mirachem 500 20% 140F, and Waterworks Heavy Duty Degreaser 20% 120F. After being cleaned, the coupons were dried in the convection oven for 10 minutes at 200F. After drying, the clean weights of the coupons were recorded.

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 micro 90 2% 150F was not successful in removing either soil. The Mirachem 500 20% 140F was successful in removing the castor oil but not the buffing compound. The Waterworks Heavy Duty Degreaser 20% 120F was successful in removing the buffing compound, but not the castor oil.
