The supplied cleaning product was used at the recommended concentration (4 oz/gal; 3.1%). The other two products were used at the ready-to-use concentration. 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 X20 reinforced wipe was attached to the cleaning sled and soaked with 1-2 sprays of cleaning solutions. Each coupon was sprayed 1-2 times with the same cleaning solution. The solution was allowed to penetrate for 10-15 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.
Chemistries Evaluated: nClean; Clorox Bathroom Cleaner; Seventh Generation Free & Clear Bathroom Cleaner;
The supplied product both removed over 85% of the bathroom soap scum soil from the surfaces using manual cleaning. The conventional product and the green product removed 70%. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
