Trial Number 1

Client Number 158

Project Number 1

Trial Purpose:

Evaluating previously tested products using gravimetric analysis

Date Run:

09/17/2001

Experiment Procedure:

Contaminants: Eight cleaners were selected based on the last previous trial. Two additional cleaners were used based on client’s current cleaning practices. Each product was diluted to 5% with DI water in a 600 ml beaker. Thirty preweighed steel coupons were coated with the Rust Veto C3 using a hand held swab. The rust preventative was allowed to sit on the coupons for 10 minutes prior to being reweighed. Following the second weighing, three coupons were immersed into each solution and allowed to soak for 3 minutes at 130 F. At the end of the 3 minutes, each coupon was rinsed in a tap water bath at 120 F for 30 seconds and dried with a heat gun at 500 F for 1 minute. After the coupons cooled to room temperature, a final weight was recorded and cleaning efficiencies were calculated.

Rust Preventatives: Houghton Rust Veto C3

Trial Results:

All ten cleaners were very successful in removing the rust preventative from the steel coupons. The lowest cleaning efficiency was 95% (Bio Might 100) and the highest was 99.99% (Inproclean 3800). Six cleaners had efficiencies higher than the Certa Clean and three were more effective than the Dasco Clean. The following table lists the calculated results for each cleaner and its rank.

Certa Clean 98.34 97.64 98.48 98.15 0.45 7
Dasco Clean 99.92 99.49 98.39 99.27 0.79 4

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 six lab selected cleaners that performed better than Certa Clean will be used in the next trial.  The second rust preventative from Stubbs will be the focus of the trial.
