To evaluate the supplied products for bathroom cleaning using manual cleaning
Date Run:
07/21/2010
Experiment Procedure:
The supplied cleaning products was used at the recommended concentration, 1.56% and the conventional product was used at 0.78%. Preweighed chrome, ceramic, porcelain and fiberglass, coupons were coated with SSL Soil 1 (Bathroom soap scum: All-in-one shampoo and conditioner 28.6%, Dry skin lotion 21.4%, Liquid hand soap 21.4%, Liquid body wash 14.3%, Deodorant bar soap 7.2% and water 7.1%.) using a handheld swab and allowed to dry for 24 hours 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 X60 reinforced wipe was attached to the cleaning sled and soaked with 5-7 sprays of cleaning solutions. Each coupon was sprayed 7-10 times with the same cleaning solution. The solution was allowed to penetrate for 30 seconds followed by cleaning in the SLW unit for 20 cycles (~33 seconds). At the end of the cleaning, coupons were wiped once with a dry paper towel. Final weights were recorded and efficiencies were calculated and recorded.
Trial Results:
The supplied product and the conventional product both removed over 85% of the bathroom soap scum soil from the surfaces using manual cleaning. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
