Trial #6

To evaluate the effectiveness of SB-33 (a D limonene and Dimethyl Glutarate mixture) and SB-10 (a t-butyl acetate and Benzyl benzoate mixture) in removing several production oils and greases from stainless steel coupons as a potential replacement for TCE unheated immersion cleaning method.

Three stainless steel coupons were used for each of the five soils being tested for a total of 15 coupons.  The initial weights of each coupon were recorded. The bottom third of every coupon was soiled by applying the corresponding soil with a swab.  The dirty weights of each coupon were then recorded.  The coupons were then subjected unheated immersion in SB-33 and SB-10 with the stir bar at 200rpm for 15 mins.   After the coupons were cleaned, they dried with a heat gun for about 2 minutes each.  The next morning, the clean weights of each coupon were taken
