To evaluate successful cleaners using elevated temperatures
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.
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.
|Cleaner||Initial wt||Final wt||% Removed|
|Bio T 300 B||0.3305||0.0168||94.92|
Success Rating:A follow up test, usually based on company input.
All four products will be tested at room temperature using ultrasonic energy.
