Trial Number 3

Trial Purpose:

To evaluate non-aqueous alternative cleaning products on the first supplied rust preventative

Date Run:

08/05/2008

Experiment Procedure:

Nine products were selected from the lab's database, www.cleanersolutions.org, based on client supplied information and past testing results. All eight were used at full strength.

Twenty-seven preweighed steel coupons were coated with rust preventative VCI 325 using a hand held swab. Dirty weights were recorded. Three coupons were cleaned in each product for five minutes using minimal agitation. No rinse was used and coupons were air dried at room temperature. Once dry, final weights were recorded and efficiencies calculated.

Trial Results:

Of the nine products tested, only one removed more than 80% of the rust preventative and there were three that removed greater than 60%. The table lists the amount of soil added, the amount remaining and the efficiency of each coupon cleaned.

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion:

The effective non-aqueous based  products will be tested along with the effective aqueous products on the first supplied rust preventative using ultrasonic cleaning.
