Trial Report

Trial Number 368

(Client Number 153, Project Number 1)

Trial Purpose: Laboratory evaluations of alternative cleaning products

Date Run: 11/10/05

Experiment Procedure:
Six preweighed aluminum coupons were coated with Keystone Nevastane 6 Food Machinery Lubricating Oil (64742-47-8, 8042-47-5, 9003-29-6) by spray application and wiping with a hand held swab. Coupons were reweighed to determine the amount of soil added.
Two aqueous products were diluted to 5% using DI water and were placed in a 500 ml glass bottle. An adapter designed to convert the liquid solution into a spray aerosol was used in conjuction with Crown Spra-Tool (propane and isobutane) as the propellant. Each aqueous product was used for about 1 minute at room temperature. After cleaning coupons were allowed to air dry for 30 minutes at room temperature. At the end of drying, final weights were recorded and removal efficiencies were calculated for each coupon cleaned.

Trial Results
The Brulin Corp product removed over 75% of the lubricant using the aerosol application technique. The other product removed less than 30%. The table
lists the amount of soil added, the amount remaining and the efficiency.
