Trial Number 5

Trial Purpose:

To reevaluate cleaners on fourth wax using longer cleaning time

Date Run:

01/28/2003

Experiment Procedure:

Five cleaners from the previous trial were used at full strength at 130 F in 600 ml beakers. Fifteen coupons from the previous trial were immersed into each beaker for 15 minutes. Coupons were then rinsed in tap water at 120 F for 15 seconds and dried using air blow off. A second final weight was recorded and efficiency at the extended cleaning times were calculated.

Trial Results:

The five cleaners all removed over 95% of the wax after the additional 15 minutes of soaking. The table below lists the amount of wax remaining after the first 5 minutes as well as how much was left after the 15 minutes of additional cleaning.
