Twelve pre-weighed stainless steel coupons, two for each adhesive, were soiled for each contaminant tested. Approximately 0.25 g of the soil was applied using a hand held swab. Each set of coupons were manually wiped with a cloth of the same material, one dipped into unheated Sta-Sol® ESS 160 100% and another in Toluene. During this process, any noticeable soil removal was observed and recorded. Coupons were allowed were wiped with a paper towel to ensure no residue of the cleaner, and afterwards final weights were recorded. The efficiency of removal was calculated for each coupon cleaned.
Stasol struggled to remove the adhesive AC-059. Although it was almost as effective as Toluene at removing AC-054 and minorly more effective at removing AC-163, it overall was less effective than Toluene.

Stasol ESS 160 was not on par with Toluene for adhesive removal and is considered a non-ideal replacement. The next trial(s) will test a list of HSPiP solvents for their effectiveness against the adhesives provided and narrow down possible replacements for Toluene.
