To evaluate the efficiency of supplied cleaner (Quicksolv DMC) and a comparative solvent (acetone) in the removal of Nisseki SAS-60E and Cut20 oils from copper coupons.
A set of twelve copper coupons were weighed on an analytical balance to determine their initial mass. Once this was completed half of the coupons were evenly soiled with about 0.5 gram of Nisseki SAS-60E oil, and the other half with about 0.5 gram of Cut20 oil using a handheld swab. The coupons were reweighed to determine the mass of the coupons with the contaminant applied.
Three coupons that were soiled with Nisseki SAS-60E oil were placed on a Gardner Straight Line Washability unit. A Kimberly-Clark Wypal reinforced paper towel was attached to the cleaning sled and soaked with one spray of Quicksolv DMC. Each coupon was sprayed once with the same cleaning solution. The cleaning unit was run for 20 cycles (~33 seconds). This same process was run on another set of three copper coupons soiled with Cut20 oil. The remaining six coupons were run through the same process but cleaned with acetone. The coupons were allowed to dry for an hour before being weighed. Final weights were recorded, efficiencies were calculated and recorded.
Chemistries Evaluated: Quicksolv DMC, Acetone
The sample cleaner Quicksolv DMC was just as effective as the acetone in removing the oils from the copper substrate. Both the Quicksolv DMC and the acetone had very high soil removal rates (97.11 – 98.84%, average 97.98% for Quicksolv DMC; 97.56 – 97.68%, average 97.62% for acetone).

Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
Both products performed at the same level on the two oils, removing over 97%.
