Trial Number 4

Trial Purpose:

To evaluate fourth client supplied wax.

Date Run:

01/28/2003

Experiment Procedure:

One product was selected from the laboratories database of testing results based on client supplied data. Five other products were also selected based on success in previous trial. All six 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 93114 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:

Only one product, Opti Clear, removed over 90% of the wax in the five minutes. Four of the remaining five removed about half of the wax. These products may benefit from a longer cleaning time. One cleaner was very ineffective, removing only about 4% of the wax. The table below lists the amount of wax applied and removed.

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 one successful product and the four marginally successful products will be used in the next trial on the fifth supplied wax.  An additional trial will be run on the four products at an extended time.
