Trial Purpose:
To evaluate supplied products for all purpose cleaning using manual cleaning
Date Run:
02/25/2014Experiment Procedure:
Preweighed ceramic, painted steel, and plastic coupons were coated with a thin layer of hydration soil using a bar and were allowed to dry for 1 hour at room temperature. The contaminated coupons were weighed again to determine the amount of soil added.
Three coupons were placed into a Gardner Straight Line Washability unit. A Wypall L30 reinforced wipe was attached to the cleaning sled and soaked with 1 spray of cleaning solutions with a VWR bottle. Each coupon was sprayed 1 time with the same cleaning solution. The solution was allowed to penetrate for 30 seconds followed by cleaning in the SLW unit for 20 cycles (~30 seconds). Efficiency was calculated for each coupon.
