The supplied cleaning products were used at the recommended concentration (4.7Non-acid, 6.25% mild acid). Preweighed chrome, ceramic 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 2-3 sprays of cleaning solutions. Each coupon was sprayed 1-2 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 measured and efficiencies were calculated and recorded.
ChemistriesEvaluated: Zbioscience A1+; 7th Generation; Clorox Bathroom;
Clorox bathroom and 7th Generation cleaner were most effective in cleaning compared to Zbioscience with efficiency of 90% for ceramic. It was not effective in cleaning neither Chrome nor plastic. Zbioscience was not effective in cleaning any surface with an average of 72%. The difference in efficiency could have resulted from different in concentration between cleaners. Comparing the data result from the previous data Clorox bathroom still had the highest average effective cleaning rate at 83%, while 7th Gen came in second with an average effective rating of 80%.
