Trial Report

Trial Number 273

(Client Number 153, Project Number 1)

Trial Purpose: Laboratory evaluations of alternative cleaning products

Date Run: 09/22/03

Experiment Procedure:
Five products were used at full strength, heated to 120 F on a hot plate. Fifteen preweighed coupons were coated with Houghton Chemical MTC 53 lubricant 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 lubricant within the five minutes of cleaning.  Many of the coupons had a residue on them.  This residue may
be removed with the addition ultrasonic cleaning or a longer rinse/drying process.

Success Rating
Lab evaluation based on vendor data.

Bio T Foam Plus was the only product removing over 85% of the lubricant.
