Six products were selected based on previous lab testing for similar cleaning scenarios. Preweighed coupons were coated with the supplied grinding fluid (Houghton - Grind (HOUC 420060) using a handheld swab and weighed a second time to determine the amount of soil added.
Each cleaner was put in a bowl and three coupons were dunked into the solution at a constant rate for 30 seconds of cleaning. The coupons were then put on a tray and when done and allowed to air dry. There was no rinse. The process was done to as closely replicate the process used on site as possible. Once dry, final weights were recorded, and efficiency calculated for each coupon cleaned.
Only one product was moderately successful, removing just under 80% of the grinding fluid. Three products removed over 50%. The table below lists the amount of soil added, the amount remaining and the efficiency for the coupons cleaned.

Longer cleaning times should improve the efficiencies for many of the selected products. All six will be evaluated on the second supplied cutting fluid.
