Trial Number 1

Trial Purpose:

To evaluate supplied products for bathroom cleaning using manual cleaning

Date Run:

02/13/2014

Experiment Procedure:

The supplied cleaning products, Scrub Bathroom Cleaner and All-purpose Clorox Cleaner, were used at the recommended dilutions (one tablet per 16 oz of water and RTU). Pre-weighed chrome, ceramic and plastic, 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). Final weights were measured and efficiencies were calculated and recorded.

Chemistries Evaluated: Scrubs Organic product; All Purpose Clorox;

Trial Results:

Both cleaners were effective at removing bathroom soap scum from ceramic, Plastic and chrome plated coupons. Scrubs organic cleaner removed on average 94% of the bathroom soil. Clorox removed 95% on average.
