Each oil was applied to pre-weighed aluminum coupon. The coupons were placed in an oven for 20 minutes at 160 F. Coupons were allowed to cool to room temperature and weighed again. Three coupons were placed in each cleaner for two minutes with stir bar agitation at room temperature. Coupons were then rinsed in tap water for 30 seconds also at room temperature. Parts air dried and then weighed one more time.
SUBSTRATE MATERIAL: Al-202-6061 T-4
CONTAMINANTS: Citgo Cutting Oils 425 & 120, Sliderite 220
CONTAMINATING PROCESS USED: Applied the oils using a swab.
All six of the chemistries cleaned very well. The Daraclean product had a dramatic increase in efficiency when compared to the previous trials. The other products tested were consistent with the results from the other trials. Table 2 lists the cleaning efficiencies from this trial and Table 3 compares results obtained in the other experiments.

Having compared the current cleaners to the client’s suggested substitutions, it is apparent that there are several choices available. In making the switch, cleaning efficiency will remain the same as is evident from the percent removal of the tested cleaners.
