To identify an alternative to Kerosene for cleaning knitting equipment.
Seven products were selected based on client request for products that can be used to clean-in-place at room temperatures. Each product was used at full strength in a 250 ml beaker. Twenty-one preweighed steel copper coupons were coated with the buffing material, Henkel Loctite Clover Silicone Carbide Grease Mix grit size (64742-52-5, 1592-21-2, 1333-86-4), 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.
Three products removed over 80% of the soil after five minutes of soaking. A few of the products were noted to have a residual cleaning fluid film remaining on the coupons after the air blow off. These products, Soy Gold 2000, 278 Super Solv and United 2002 Harvest Gold, were blotted dry in an attempt to remove the cleaning product but leave the uncleaned soil behind. The table below lists the amount of soil added, the amount remaining after cleaning and the efficiency for each coupon cleaned.
