Trial Number 12

Trial Purpose:

To evaluate four products for bathroom cleaning

Date Run:

08/12/2009

Experiment Procedure:

The supplied cleaning products were used at the supplied concentrations. 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 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 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.

In addition to the supplied products, one traditional cleaning product was used for comparative purposes. A sixth product that uses electrolyzed water was included in the testing.

Trial Results:

All of the products tested were effective at removing over 90% of the bathroom soap scum from the three surface types. The ActiveIon unit had the top cleaning efficiency, followed by the MD Stetson PC 116.
