To evaluate the effectiveness of the supplied cleaners with bike soil removal on provided substrates.
Date Run:
11/16/2016
Experiment Procedure:
Fifteen stainless steel coupons and fifteen aluminum coupons were weighed to attain initial weights. Bike soil was prepared using 1.6 grams of bike soil and 50 drops of Tri-flow lubricant. Each coupon was then soiled with 1.6 grams of bike soil and 50 drops of Tri-flow lubricant. Dirty weights were recorded. Three coupons were placed in the manual SLW machine at a time and sprayed twice each with the selected cleaner, as well as the paper towel. The coupons were then run for a total of 5 cycles. The process was repeated for all of the 30 coupons. After the cleaning process, the coupons were allowed to dry. Subsequently, the dried coupons were weighed to attain final weights.
