Trial Purpose:
To evaluate the effectiveness of Shark Ninja formulations in the removal of soils on various surfaces.
Date Run:
12/22/2019Experiment Procedure:
Six pre-weighed coupons, three of each substrate per cleaner, were soiled with half a gram of DCC-17 soil (33% lard; 33% shortening; 33% vegetable oil and 1% carbon black powder) distributed onto each coupon using a swab. Dirty weights were recorded after the coupons had dried for 24 hours at room temperature (68° F). Three coupons of the same substrate were aligned into a Single Line Washing Unit (SLW) with Wypall X60 attached to the cleaning sled. The Wypall X60 reinforced wipe along with the coupons were all sprayed three times with the cleaner and then allowed to soak for 30 seconds. Afterwards the SLW was activated, and the coupons were cleaned for 20 cycles. Cleaned coupons dried overnight at room temperature before the final weights were recorded.
