To evaluate supplied products for GS 37 bathroom cleaner performance.
The supplied cleaning products were used at the requested concentration and a third product (conventional) was used at full strength as recommended by the vendor for bathroom cleaning.
Preweighed ceramic, chrome 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 hand held 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 Kimberly Clark Reinforced paper towel 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. Efficiencies were calculated and recorded.
The two supplied products removed over 85% of the bathroom soap scum soil from all surfaces except one (One of the two products removed 80% from the chrome surface). The supplied conventional product removed less than 50% of the soil from the surfaces. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
