Trial Purpose:
To conduct testing on possible drop in solvents for Dow grease.
Date Run:
02/03/2016Experiment Procedure:
Stainless steel coupons were selected and arranged into rows of 3 coupons, a row per cleaner. Initial weights were taken, and coupons were soiled and reweighed. The lower third of the coupons were soiled. beakers with drop in solvent replacement solutions were set up on stirring plates equipped with a stir bar. The coupons were immersed for 5 minutes. Observations were taken during the cleaning process. The coupons were dried on a rack for 15 minutes. Final weights were recorded.
Trial Results:
Some drop in solvents were effective on the Dow Grease. Based on visual observations, the Solstice products seemed more effective cleaners.
