Trial Report



Trial Number 376

(Client Number 153, Project Number 1)

Trial Purpose: Laboratory evaluations of alternative aerosol cleaning products

Date Run: 11/08/06

Experiment Procedure:
Thirteen products were selected for testing based on soil removal. Six products were diluted to ~15% using DI water and one was used at 10%. The other six products were used at full strength in 250 ml beakers. Products were used at room temperature.
Thirteen 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 coupons was cleaned in each solution for 5 minutes using no agitation. 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.

Testing was conducted as a preliminary screening and did not follow the triplicate testing process normally followed.

Trial Results
Five of the thirteen products removed over 65% of the soil mix from the individual coupons. Two products removed just over 40%. These seven products
were considered acceptable for continued testing. The table below lists the amount of soil added, the amount remaining and the efficiency for each
coupon cleaned.
