Trial #2
To evaluate client supplied cleaning solution on all listed contaminants and on several substrates.
The cleaning solution was used at full strength in a 600 mL beaker. The solution was used at room temperature. Coupons were cleaned for five minutes. Rinsing was performed for two minutes using tap water at 120 F and air dried for about two hours also at room temperature. After drying is complete, final weights are recorded and efficiencies are calculated.
SUBSTRATE MATERIAL: Aluminum (202-2024 T-3); Cold Rolled Steel (202-1020); Stainless Steel (202-10 B-85); Glass; Liquid
CONTAMINANTS: Table 1 lists the contaminants and the related CAS#s for this trial.
Table 1. Contaminants Cleaned
Contaminant CAS #
grease 64742-47-8
lubricant 64742-47-8, 9003-29-6
coating 64742-47-8, 64742-52-5
flux
buffing 64-56-1, 1314-13-2, 119-47-1, 8052-10-6
CONTAMINATING PROCESS USED: Three preweighed coupons were contaminated for each of the listed soils using a hand held swab.
The Product evaluated was successful on all the contaminants except for one. It only removed 37% of the coating that was applied to the stainless steel coupons. All other contaminants were completely cleaned (100%). Table 2 lists the efficiencies for each substrate and contaminant studied.
