Trial Purpose:
To evaluate successful cleaners using elevated temperatures
Date Run:
02/11/2004Experiment Procedure:
Four cleaners were selected from the past trials for this wax. All products were used at full strength also in 250 ml beakers. All products were heated to 100 F on a hot plate. Twelve preweighed ceramic coupons were coated with client supplied wax, Zopher Mills Inc No 1563 Wax (mixture of waxes and resins). The wax was first melted using a Master Appliance heat gun in a beaker and applied directly to the coupon surface. The coupons were allowed to cool to room temperature before weighing a second time. Three coupons were cleaned in each solution for 30 minutes using stir-bar agitation. Coupons were rinsed in tap water for 15 seconds at 120 F, followed by air blow off at room temperature.
Once dry, coupons were weighed a final time and efficiencies for each cleaner were calculated.
Trial Results:
All four products removed over 75% of the wax within 30 minutes. Two products, Uni Clear and Bio T 300 B, removed over 90% of the soil. The table lists the amount of soil applied and remaining after cleaning.
