removing buffing compound from brass
Products were based on the compatibility of substrate and removal of foreign substance. Used 5% concentration and heated the samples at 135F. The coupons were immersed in a product for 5 minutes, rinsed for 30 seconds in tap water at 120F and dried in 30 seconds using compressed air is room temperature.
Coupons were coated with used oil. Using a handheld swab and allowed to dry for 144 hours at room temperature. The contaminated coupons were weighed again to determine the amount of soil added. After cleaning process the final weights were recorded, efficiencies were calculated and recorded.
|Cleaner||Initial wt||Final wt||% Removed|
|buff clean 14L|
|alconox det 8|
|daraclean kx 43|
|buckeye 100xl poly|
|us polychem spray jet|
Success Rating:Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
The one and only product that has passed our test with an 85% or better is buff clean 14L with a percentage of removal of 90.26%. The other products has not passed the passing rate of contaminant removal of 85%.
