Trial Number 3

Trial Purpose:

To evaluate successful cleaner from previous trial on second contaminant.

Date Run:


Experiment Procedure:

The Gemtek product was diluted to 10% using DI water in a 600 ml beaker and heated to 130 F on a hot plate. Six preweighed coupons were coated with Mobil Oil Corp Mobilarma 245 (64742-88-7) using a hand held swab. Coupons were weighed again. Three coupons were cleaned for 5 minutes and the other three were cleaned for 10 minutes. Both cleaning utilized stir-bar agitation. Coupons were rinsed in tap water at 120 F for 30 seconds and dried using a Master Appliance heat gun at 500 F for 1 minute. Final weights were measured and efficiencies were calculated for the two cleaning times.

Trial Results:

Both cleaning times resulted in complete removal of the Mobilarma 245.  The table lists the efficiencies for both cleaning times.
