One new product was tested at room temperature to use as a possible substitute for the clients current cleaning solvent.
Three preweighed coupons were coated with Hangsterfer Laboratories Hard Cut 5418 cutting fluid and three were coated with Master Chemical Corporation Trim Sol SF (8002-05-9, 61789-85-3, 68410-99-1, 68991-48-0, 68603-15-6) cutting fluid using a handheld swab. The contaminated coupons were weighed a second time to determine the amount of soil added. Three coupons were immersed into each cleaning solution and manual raised and lowered in the cleaning solution to provide mechanical agitation. After one minute of cleaning, the coupons were removed and dried for 30 seconds using compressed air at room temperature. Following air drying, the coupons were weighed a final time to determine the amount of soil remaining. Efficiency for each coupon was determined and average cleaning results for each product were calculated.
