Project Number 1

Trial Purpose:

To evaluate the effectiveness of the Alpha Chemical Sample C formula against the Alpha Chemical Sample G formula and the Alpha Chemical Sample M formula on the removal of vehicle dirt.

Experiment Procedure:

All painted steel coupons were pre-weighed and had about one half gram of Vehicle Dirt soil (45% Lithium grease, 39% motor oil, and 16% bike dirt) were distributed onto each coupon. Three painted steel coupons were cleaned by each of the three different Alpha Chemical formulations. The dirty weights were recorded; three coupons of the same substrate were aligned into a Single Line Washing Unit (SLW) with Wypall X60 attached to each 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 Single Line Washing Unit (SLW) was activated and cleaned for 20 cycles. The clean coupons were then allowed to dry at room temperature before the final weights were recorded. This process was repeated 5 more times for every set of coupons with its respected cleaner, with all the data and observations recorded.
