Trial Report

Trial Number 375

(Client Number 153, Project Number 1)

Trial Purpose: Laboratory evaluations of alternative aerosol cleaning products

Date Run: 10/12/06

Experiment Procedure:
Six products were selected for testing based on an aerosol formulation for brake cleaning. Another product was selected but tested using a manual pumping delivery. The products were used at full strength in spray cans as delivered by the vendors. Products were used at room temperature.

Seven 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. One coupon was cleaned in for 30 seconds using the spray can. Coupons were weighed and efficiencies were calculated.

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