Trial Report



Trial Number 374

(Client Number 153, Project Number 1)

Trial Purpose: Laboratory evaluations of alternative aerosol cleaning products

Date Run: 10/12/06

Experiment Procedure:
One product was retested from the previous trial at a higher concentration. An additional two products also were selected for testing based on equipment compatibility and soil removal. The three products were used at full strength in 250 ml beakers. Products were used at room temperature.

Nine preweighed aluminum coupons were coated with a collection of brake/engine soil collected from an automobile shop. The coupons were allowed to sit for several days before a second weight was recorded. Three coupons were cleaned in each solution for 5 minutes using minimal agitation from a magnetic stir bar. Coupons were then rinsed in tap water for 15 seconds and dried using air blow off at room temperature for 30 seconds. Following drying, final weights were recorded and cleaning efficiencies were calculated.

Trial Results
The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
