Trial #3
To evaluate selected products on third supplied metal working fluid using simulated cleaning process
Preweighed coupons were coated with the supplied rust preventative (WA Wood FPS Rustnot) coating using a handheld swab and weighed a second time to determine the amount of soil added.
The same six cleaners were 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.
Two products were moderately successful, removing just under 80% of the cutting fluid. Three products removed over 60%. 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 third supplied metal working fluid.
Solsafe 245 had the highest combined cleaning efficiency followed by Metalnox M6310 when looking at all three fluids.
