Trial Number 378

(Client Number 153, Project Number 1)

Trial Purpose: Laboratory evaluations of alternative aerosol cleaning products

Date Run: 11/27/06

Experiment Procedure:
Five products were selected for testing based on previous testing on the selected soil. All five products were diluted to 3% using DI water. Products were used at room temperature.
Fifteen 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 less than one minute using low pressure spray. Coupons were not rinsed but were dried using air blow off at room temperature for 10 seconds. Following drying, final weights were recorded and cleaning efficiencies were calculated.

Trial Results
All five products removed over 95% of the soil at the lower dilutions. However, all solutions had an increase in foaming. The table below lists the
amount of soil applied, the amount remaining and the efficiency for each coupon cleaned.

Success Rating
Lab evaluation based on vendor data.

Conclusion
All five were effective at the lower concentrations but had increased foaming levels. Higher concentration (~10%) may be used in EnviroCaddie system.
