Trial #0
To evaluate the effectiveness of CLEANER in the removal of SOILS on various surfaces.
Thirty pre-weighed coupons, six per cleaner, were contaminated with either (A) maintenance soil or (B) production soil using a swab. Coupons contaminated with maintenance soil aged for 30 minutes at 105 F, and 30 minutes at 220 F for production soil. Coupons were immersed into the cleaning solution and then rinsed in a tap water bath. Coupons were left to air dry for 30 minutes at room temperature before oven drying at 105 F for 30 minutes. Coupons were cooled before final weights were recorded.

Cleaner 1 with soil A, cleaner 2 with soil B, and cleaner 5 with soil A yielded unusual numbers. The likely cause is that the soil absorbed the cleaning product, causing the clean weight to weigh more than the initial weight of the coupons.
The Sycamore degreaser products are more effective than Crystal Simple Green cleaning product at removing oil from stainless steel.
