Trial Purpose:
To evaluate two Do-It-Yourself formulation following kit instructions for all purpose cleaning
Date Run:
04/17/2008Experiment Procedure:
The supplied cleaning products were used at the recommended concentration. Two products were included for comparison and used at its ready to use concentration.
Preweighed ceramic, plastic and 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 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. 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). Final weights were recorded, and 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.
