Trial Number 0

Trial Purpose:

To evaluate two Do-It-Yourself formulation following kit instructions for bathroom cleaning.

Date Run:

04/17/2008

Experiment Procedure:

The two supplied cleaning product was diluted to vendor recommended concentrations for bathroom cleaning. Two other household products were included for comparative purposes. Preweighed fiberglass, ceramic and chrome coupons were coated with SSL Soil 1 (Bathroom soap scum: Vaseline Dry Skin Lotion 21.4%, Dial Clean Rinsing Body Wash 14.3%, Market Basket Shampoo & Conditioner (Pert)28.6%, Soft Soap Natural Liquid hand soap 21.4%, Coast 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 Wypal reinforced wiper 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 cleaning unit was run for 20 cycles (~33 seconds). Final weights were recorded, efficiencies were calculated and recorded.

Trial Results:

The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.

Success Rating:

Test incomplete or inconclusive.

Conclusion:

Results were inconsistent and many of the products had negative cleaning efficiencies. This may have been due to cleaner residue being left on the coupons, especially for the EZ Clean Green Soft Scrub. A follow up retest will be performed.
