Trial #25
To evaluate the effectiveness of Micro-90 (2% cleaner, 98% water), BG-Clean 402 (10% cleaner, 90% water), Simple Green (10% cleaner, 90% water), and 1400 GD Detergent and Degreaser (10% cleaner, 90% water) in removing wax from stainless steel coupons as a preliminary test for Precision Fabricators
three stainless steel coupons were used for each of the four cleaners for a total of 12 coupons. The initial weight of each coupon was recorded before applying the wax. The bottom third of each coupon was soiled by adding Meguiar's Cleaner Wax using a swab. The dirty weights of all coupons were then recorded. The coupons were then put into heated ultrasonics at 120F in Micro-90 (2% dilution with water), BG-Clean 402 (10% dilution with water), Simple Green (10% cleaner, 90% water), and 1400 GD Detergent and Degreaser (10% cleaner, 90% water) for 15 minutes. After the coupons were cleaned, they were left to air dry overnight. The next morning, the clean weights of all of the coupons were recorded.

Coupon 5 appears to be an outlier, as more than 100% of contaminants were removed. This could be caused by the coupon not being completely clean, therefore more than what was applied was removed. Overall, Micro-90 and BG-Clean 402 were effective in cleaning wax from stainless steel. 1400 GD and Simple Green were ineffective in cleaning wax from stainless steel.
