Two sets of 9 coupons were weighed and soiled with the Jowat Hot-melt adhesive and wilsonart banding adhesive and then weighed again. The coupons were then scrubbed for 30 seconds with a rag that had been soaked in one of the three solvent mixtures. The first being a mixture (by weight) of Acetone (34%) and Ethyl Acetate (66%), the second being anisole (21%) and 1,3-dioxolane (79%), and the last being acetone (20%) and anisole (80%). After being wiped, the coupons were allowed to air dry overnight and weighed a final time to evaluate how much of the soil was removed.

The results of this test were less than promising, the range of percent removal was incredibly broad, with 7 of the 18 trial coupons reporting removal percentages significantly over 100%. This could be due to a variety of factors, it could be due to the solvent mixtures attacking the substrate, inaccuracies in analytical equipment, or some other confounding variable. A re-test is necessary.
