To determine a drop in replacement
The purpose of this trial is to determine a drop in replacement for Machinary Manufacturer's current usage of Diversey Jettacin cleaner. For a successful chemistry to be chosen it must meet several things:
1) Must be able to remove various cutting oils and packing greases as good as or better than Jettacin.
2) Preferably have no VOC content or very low contents
3) Must be able to be rinsed easily to allow painting after drying.
From the three variables listed above ten different aqueous chemistries were chosen. The effectiveness in removing three different packing greases will be evaluated. Grease #1 is a Valvoline heavy grease. Grease #2 is a heavy grease. Grease #3 is also a heavy grease. Cleaning was done in a simple immersion test for 10 minutes at 120 F. After cleaning the coupons were rinsed in room temperature tap water for ten seconds and then allowed to air dry. Cleanliness was based on visual effectiveness of each cleaner and each cleaner was given a grading of 1 to 10 for each grease. 1 being the best remover and 10 being the worst.
SUBSTRATE MATERIAL: Steel
CONTAMINANTS: Various heavy greases and cutting fluids

From the results in Table 1, the Ardrox 6333 and the Polyspray 790 XS were tested further against the Jettacin in a Miele G7735 pressure wash unit. This time, the coupons were contaminated with a variety of cutting oils and greases along with the pine-tar preservative obtained from the client. All contaminants were applied with a styrofoam swab and then allowed to set for 4 hours.
Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
From the above results, two chemistries were tested further, the Ardrox 6633 and the U.S. Polychem Polyspray XS in a pressure wash unit. The pressure washer operates at a maximum pressure of 13.
