Trial Purpose:

To evaluate products on supplied knitting oil

Date Run:

05/06/2004

Experiment Procedure:

Seven products were selected based on the previous two trials. Each product was used at full strength in a 250 ml beaker. Twenty-one preweighed steel copper coupons were coated with the Chevron Knit Oil ISO 32 using a hand held swab. Coupons were weighed a second time to determine the amount of soil added to each coupon. Three coupons were cleaned in each solution for 5 minutes using stir-bar agitation. After cleaning parts were dried using air-blow off. Coupons were then weighed a final time and efficiencies were calculated.

Trial Results:

All seven products removed over 87% of the knit oil. Soy Gold 2000 and United 2002 both left residue behind after the air blow off. This residue was not oil but rather the cleaning product itself. The table below lists the amount of soil added, the amount remaining and the efficiency for each coupon.
