Client #28 | Project #2 | Trial #3 | CleanerSolutions Database: A Simple Solution for Solvent Substitution for Surface Cleaning.

Trial Purpose:

To evaluate longer cleaning time without rinsing

Date Run:

03/15/2004

Experiment Procedure:

Four cleaners were selected from previous trial. Three aqueous based cleaners were diluted to 10% using DI water in 600 ml beakers. One semi-aqueous product was used at 50% diluted with DI water. All of the products were heated to 120 F on a hot plate.
Twelve preweighed aluminum coupons were coated with the second client supplied oil, Castrol Moly Dee Tapping Fluid. The oil was applied to coupons using a swab and then heated for 10 minutes using a Master Appliance heat gun. The coupons were allowed to cool to room temperature before weighing a second time.
Three coupons were cleaned in each solution for 10 minutes using stir-bar agitation. Coupons were not rinsed but were dried using air blow off at room temperature. Once dry, coupons were weighed a final time and efficiencies for each cleaner were calculated.

Trial Results:

Cleaning the soiled coupons for a longer time without rinsing was equal to the cleaning at five minutes with a rinse for all four products. The table lists the amount of soil initially added, the amount remaining after cleaning and the efficiency for each coupon cleaned.
