Trial Report

Trial Number 269

(Client Number 153, Project Number 1)

Trial Purpose: Laboratory evaluations of alternative cleaning products

Date Run: 09/22/03

Experiment Procedure:
Six products were used at full strength, heated to 120 F on a hot plate. Eighteen preweighed coupons were coated with Dauber Chemical Co Tectyl 891 Class 1 Cosmoline grease (8052-41-3, 98918-69-4, 64742-65-0, 68608-26-4) and allowed to dry for three days and reweighed.
Three coupons were cleaned in each solution for 5 minutes using stir-bar-agitation, rinsed in a tap water bath for 15 seconds at 120 F and dried using air blow off for 30 seconds at 68 F. Coupons were allowed to dry overnight and then reweighed a final time. Efficiencies were calculated.

Note: Bio T Foam Plus was sprayed onto coupons at room temperature and allowed to sit for 5 minutes. The cleaner was then rinsed off.

Trial Results
Only one product removed over 85% of the soil during the 5 minute immersion cleaning.  A second product removed just under 70%.

Success Rating
Lab evaluation based on vendor data.

Increased cleaning time or the addition of agitation would improve the cleaning for 278 Super Solv and VG 151.
