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.
| Cleaner | Initial wt | Final wt | % Removed |
| Uni Clear | 0.4814 | 0.0282 | 94.14 |
| 0.4273 | 0.0356 | 91.67 | |
| 0.2427 | 0.0021 | 99.13 | |
| Bio T 300 B | 0.3305 | 0.0168 | 94.92 |
| 0.2039 | 0.0031 | 98.48 | |
| 0.3736 | 0.0712 | 80.94 | |
| D Limonene | 0.4211 | 0.0934 | 77.82 |
| 0.2797 | 0.0769 | 72.51 | |
| 0.4047 | 0.0899 | 77.79 | |
| Citrus Pure | 0.5213 | 0.1064 | 79.59 |
| 0.3546 | 0.0032 | 99.10 | |
| 0.3142 | 0.0631 | 79.92 |
Success Rating:
A follow up test, usually based on company input.Conclusion:
All four products will be tested at room temperature using ultrasonic energy.
