Trial Number 7

Trial Purpose:

To reevaluate supplied product as compared to a conventional cleaning product of bathroom cleaning following GS 37 standard.

Date Run:

12/23/2008

Experiment Procedure:

The supplied cleaning product was used at the requested concentration (5%) for bathroom cleaning. Preweighed chrome 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 wiped once with a dry paper towel. Final weights were recorded. Efficiencies were calculated and recorded.

Trial Results:

The follow up test resulted in the Super H2O2 having a higher efficiency than the Formula 409 All Purpose cleaner. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
