To evaluate the efficacy of cleaners in removing oil and dirt from brass coupons
Date Run:
12/01/2015
Experiment Procedure:
Initial weights were recorded for the brass coupons. The coupons were coated with the half a gram of the oil contaminant and re- weighed. The coupons were then submerged for one minute into different cleaners to be determine the % of contaminant removal. For five of the cleaners, the coupons were place in a beaker containing DI water. Once removed from the DI water, a blow dryer was used for 20 seconds to remove residual water. Visual observation and re-weighing of contaminate removal were recorded.
