Trial Number 1

Trial Purpose:

To evaluate supplied recipes for bathroom cleaning using manual wiping.

Date Run:

01/27/2009

Experiment Procedure:

The supplied cleaning formulations were made up following supplied recipes. An additional product was included 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 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 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 using a water soaked paper towel to rinse any cleaner residue (if necessary and then wiped once with a dry paper towel. Final weights were recorded. Efficiencies were calculated and recorded.

Trial Results:

The supplied products and industry product were effective in removing the Bathroom soil with a manual wiping action. The table lists the amount of soil initially added and the amount remaining after cleaning and the product efficiency for each coupon cleaned.
