Experiment Procedure:

 Initial weights of the coupons were recorded.  The coupons were then soiled with 1.6g of bike soil.  Dirty weights were recorded and they were placed in threes into the Manual SLW machine.  The coupons and paper towel were both sprayed twice with the selected cleaner. 5 complete back and forth cycles were run and the coupons were then allowed to dry.  Once dry, the clean weights were recorded.  This process was repeated for each cleaner.
