Trial #1
Preliminary testing of potential alternative cleaners to determine efficacy in removing buffing compound and castor oil.
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 Surface Cleans 930 2% 100F, SC Aircraft and Metal Cleaner 20% 130F, and Citranox 20% 130F. 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.

The citranox left a residue even after drying, so the clean weight values may not accurately represent the true efficacy.
Both the Surface Cleanse 930 2% 100F and SC Aircraft and Metal Cleaner 20% 130F were only successful in removing the castor oil. The Citranox 20% 130F was successful in removing both soils. However, the citranox left a residue even after drying, so future testing with this product will require a rinse step before drying.
