Trial Purpose:
Laboratory evaluations of alternative aerosol cleaning products
Date Run:
11/08/2006Experiment Procedure:
Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning.
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.

Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.Conclusion:
The products that showed good cleaning abilities in the preliminary testing phase will be evaluated further.
