Trial Number 2

Client Number 196

Project Number 1

Trial Purpose:

To evaluate products from previous trial on second supplied wax

Date Run:

01/27/2003

Experiment Procedure:

Three products were selected from the laboratories database of testing results based on client supplied data. Three other products were also selected based on being successful in removing bees wax in the previous trial.
One product was diluted to 20% using DI water in a 600 ml beaker as recommended by the vendor. In addition, five semi-aqueous products were used at full strength in 600 ml beakers. The products were heated to 130 F on a hot plate. Eighteen preweighed ceramic coupons were coated with client supplied Roger Reed 9805 wax. The wax was first melted using a Master Appliance heat gun in a beaker and applied to the coupons using a swab. The coupons were allowed to cool to room temperature before weighing a second time. Three coupons were cleaned in each solution for 5 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:

Three of the six products, Opti Clear, Citrikleen XPC and Bio T 200 A, were successful in removing over 80% of the wax during the 5 minute immersion cleaning. Citraburst 7 removed just over a third the wax, but showed signs of lifting the wax off of the coupons. The USA Wash product created a film across the surface of the coupons resulting in a negative percent removal. The table below list the amount of wax added and removed for each product.

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion:

The three cleaners that removed over 80% of the 98045 Wax from Roger Reed will be used on the third supplied wax.  In addition, the Citriburst 7 will also be used due to its success in the previous trial.
