Trial Number 4

Trial Purpose:

To evaluate the five previously tested products on the fourth supplied oil.

Date Run:

08/21/2006

Experiment Procedure:

Five successful products from the first three oil removal trials were evaluated on the fourth oil. The products were diluted to 5% in 600 ml beakers using DI water and heated to 130 F on a hot plate.
Fifteen pre-weighed coupons were coated with Lamson Oil Co Heavy Draw 1290 using a hand held swab. Coupons were weighed a second time to determine the amount of oil added. Three coupons were cleaned in each solution for five minutes using minimal stir bar agitation. Coupons were rinsed for 15 seconds in a tap water bath at 120 F and dried using a Master Appliance Heat gun at 500 F for 30 seconds. Once dry coupons were weighed a final time and product efficiencies were calculated.

Trial Results:

Three of the five products removed over 85% of the oil within five minutes of immersion cleaning. The follow table lists the amount of oil added, the amount remaining and the efficiency for each coupon cleaned.
