Trial Purpose:
To evaluate the effectiveness of CLEANER in the removal of SOILS on various surfaces.
Date Run:
01/31/2019Experiment Procedure:
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.
Success Rating:
A cleanliness study, addressing only various analytical techniques.Conclusion:
The Sycamore degreaser products are more effective than Crystal Simple Green cleaning product at removing oil from stainless steel.
