Trial #2
To evaluate the effectiveness of cleaning with Sol safe 245 for two soils
One product was selected from previous trial based on effectiveness. The product was used at full strength in a 400 ml beaker and was evaluated at room temperature. Three pre-weighed aluminum coupons were coated with each soil. All coupons were cleaned in the cleaner for 10 minutes using no agitation and then were manually wiped with a Kimberly-Clark reinforced paper towel for 5 seconds. At the end of cleaning, the coupons were allowed to air dry at room temperature overnight. Final weights were recorded, and efficiencies were calculated.
The product worked very well with one soil (Antiseize) but was not as effective with Molydry Film Lube based on 10 minutes immersion cleaning and manual wipe. The table lists the amount of soil added, the amount reaming and the efficacy of the product for each coupon cleaned.

The increased time improved the effectiveness of Solsafe 245 on both soils. However, the molydry film lube removal was still under 80%. Additional testing, we will be conducted on other possible cleaners to find one that works well on all five soils.
