Trial Number 482

(Client Number 153, Project Number 1)

Trial Purpose: To remove graffiti from stainless steel using immersion cleaning

Date Run: 03/10/09

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 in tap water at 120 F and dried using compressed air at room temperature.

Coupons were coated with the contaminant using a handheld swab and allowed to dry for 120 minutes 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.
