Trial Number 27

Trial Purpose:

To test the effectiveness of Clorox Liquid Bleach in the removal of Glass Soil from various substrates.

Date Run:


Experiment Procedure:

A Clorox Liquid Bleach solution was created by mixing 4 (mL) parts liquid bleach and 192 (mL) parts water. Then, 3 coupons of each substrate (chrome, glass, mirror) were collected and initial weights were taken. SSL Soil 2 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 Gardner-scrub Abrasion Tester machine. Wypall cleaning cloths were attached to each of the 3 cleaning blocks used for the test. Each Wypall cloth and all coupons received 2 sprays of the Clorox Liquid Bleach solution and the Gardner-scrub Abrasion Tester 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.
