Four glass coupons were obtained and weighed for each of the seven cleaners. One coupon was soiled with one rosin by applying the rosin to the bottom third of the coupon with a swab and a soiled weight was obtained. The cleaning solutions were prepared for heated immersion by the following concentrations and temperatures: Smart Solve 605 100% at 150°F, RB Degreaser Cleaner 20% at 180°F, Valtron SP 2275 2% at 150°F, SC Actisolv 50% at 120°F, Propylene carbonate 100% at 180°F, Dimethyl glutarate 100% at 180°F, and SC Maxisolv 100% at 120°F. Once cleaners reached the proper temperature, the coupons were submerged into their respective cleaners for 30 minutes. After 30 minutes had passed, coupons were allowed to air dry if needed and a final clean weight was obtained. Effectiveness of cleaning was determined for each solution.

Dimethyl glutarate and SmartSolve 605 were the only two cleaners that effectively removed all four rosin contaminants on the substrate within 30 minutes of heated immersion.
