Trial Number 5

(Client Number 220, Project Number 1)

Trial Purpose: To evaluate five new products on soil number 2

Date Run: 04/30/04

Experiment Procedure:
Five products were selected based on client request for vapor degreasing solvents. Each product was used at full strength in a 250 ml beaker and heated to 96 F on a hot plate.
Fifteen preweighed aluminum coupons were coated with the Cargill, Inc Canola Oil (120962-03-0) using a hand held swab. Coupons were weighed a second time to determine the amount of soil added to each coupon. Three coupons were cleaned in each solution for 5 minutes using stir-bar agitation. After cleaning parts were allowed to sit for 10 minutes for drying at room temperature. The coupons were weighed a final time and efficiencies were calculated.

Trial Results
All five products removed over 87% of the second soil. The table lists the amount of soil added, the amount remaining and the efficiency for each
coupon cleaned.
