Trial Number 18

Trial Purpose:

To evaluate the effectiveness of the removal of glass soil from chrome, mirror, and glass using Bona cleaner.

Date Run:


Experiment Procedure:

Three coupons of each substrate (chrome, glass, and mirror) were collected and initial weights were taken. Glass soil was applied to each coupon and allowed to air dry for 24 hours. After the 24 hour dry time, the weights of the newly contaminated coupons were measured. All coupons were placed into a Straight-Line Washability (SLW) machine. A KC Wypall cleaning cloth was attached to the cleaning block used for the test. The Wypall cloth and all coupons received 2 sprays of the Bona Cleaner and the SLW machine was run for 20 repetitions, simulating 20 manual wipes. Once cleaning concluded, the cleaned coupons were allowed to air dry for 24 hours. After 24 hours, the weights of the cleaned coupons were measured. 

Trial Results:

Bona cleaner was effective for the removal of glass soil from all three substrates. It had an average effectiveness of 93% for chrome, 92% for mirror and 91% for glass.
