Trial Number 0

Trial Purpose:

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.

Success Rating:

Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.

Conclusion:

Although all the cleaners worked well, SolSafe has the highest percentage of oil removal.
