Trial Number 452

(Client Number 153, Project Number 1)

Trial Purpose: To remove vanishing cutting fluid from aluminum using immersion cleaning

Date Run: 07/29/08

Experiment Procedure:
Products were selected based on the compatibility of substrate and for removal of the contaminant. Five percent concentrations were used and heated the samples at 130F. The coupons were immersed in a product for 5 minutes, rinsed with tap water and dried using room temperature compressed air.

Coupons were coated with vanishing cutting fluid using a handheld swab and allowed to dry for one hour at room temperature. The contaminated coupons were weighed again to determine the amount of soil added. After cleaning process the final weights were recorded, efficiencies were calculated and recorded.
