Trial Report



Trial Number 9

(Client Number 341, Project Number 1)

Trial Purpose: To evaluate three supplied products for bathroom cleaning as part of three part experiment to evaluate product at one concentration for multiple cleaning tasks.

Date Run: 06/02/11

Experiment Procedure:
The selected cleaning products were used at the recommended concentration (2.4%). Pre-weighed chrome, ceramic and fiberglass, coupons were coated with SSL Soil 2 (Bathroom soap scum: All-in-one shampoo and conditioner, Dry skin lotion, Liquid hand soap, Liquid body wash, Deodorant bar soap and water) 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). In this test, coupon was not rinsing and wiped after cleaning process to represent the realistic cleaning performance. Final weights were recorded and efficiencies were calculated and recorded.

Trial Results
One of the selected product (MD Stetson 101) removed over 90% of the bathroom soap scum soil from the surfaces using manual cleaning. The other
products removed 83% of the bathroom soap scum. Visually, all bathroom sumps were removed clearly, but some of the cleaner residue were remained on
coupons. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.

Success Rating
A follow up test, usually based on company input.

Conclusion
The MD Stetson PC 101 Neutral & Glass Cleaner had an overall average efficiency over 90% and performed better than the both the comparative products. This product also was the most effective on the all purpose soil. Next phase will be to evaluate products on glass cleaning at the same concentration.
