Trial Number 6

One product was selected from the laboratories database of testing results based on client supplied data. Four other products were also selected based on success in previous trial. All six products were used at full strength in 600 ml beakers. The products were heated to 130 F on a hot plate. Fifteen preweighed ceramic coupons were coated with client supplied Roger Reed 98033 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.

Only one product, Opti Clear, was successful in removing a majority of the wax within the five minute soak. Two others, Citrikleen XPC and Bio T 200 A, removed over half of the wax. The other two products removed less the a third of the wax. The top three cleaners would benefit from increased cleaning time or agitation. The table below lists the amount of wax added and removed during the cleaning process.

Table 1. Wax Removal

The three cleaners removing over 50% of the wax will be used in the next trial on the sixth supplied wax.
