Trial Number 3

Trial Purpose:

To evaluate supplied products for all purpose janitorial cleaning

Date Run:

01/31/2007

Experiment Procedure:

The supplied cleaning products were used at the recommended concentration (2%, 2% and 1.5%). Nine preweighed ceramic, six plastic and six steel coupons were coated with Hucker's Soil Formulation (Jif Creamy Peanut Butter 9.2%, Salted Butter 9.2%, Arrowhead Mills stone ground wheat flour 9.2%, Egg Yolk 9.2%, Evaporated milk 13.8%, Distilled water 45.8%, Printer's ink with boiled linseed oil 0.9%, Shaws saline solution 2.7%) 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. AA 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). At the end of the cleaning, coupons were wiped once with a dry paper towel. Final weights were recorded and efficiencies were calculated and recorded.

Trial Results:

All three products were effective in removing the soil with a manual wiping action. Two of the products had lower efficiencies for removing the Hucker's soil from the plastic coupons. The third product, Blue Jay, had lower efficiency on the steel coupons. The table lists the amount of soil added and the amount remaining after cleaning and the product efficiency for each coupon cleaned.

Success Rating:

A follow up test, usually based on company input.

Conclusion:

The three products had an overall average efficiency over 85% and would be considered effective according to the Mass EPP protocol for an all purpose cleaner.
