Trial Purpose:
To evaluate three supplied products for all purpose cleaning.
Date Run:
07/14/2006Experiment Procedure:
One supplied cleaning products were diluted with DI water to vendor recommended concentration for all purpose Cleaning (20:11) and the other two were used at full strength.
Nine preweighed ceramic, nine plastic G-10 and nine painted 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. A Professional Painter's Rag 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). 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:
All three products worked well on the painted steel and fiberglass coupons. Only the Heavy Duty cleaner had moderate success on the ceramic coupons. The table lists the amount of soil added, the amount remaining and the percent removed for each coupon cleaned.

Success Rating:
A follow up test, usually based on company input.Conclusion:
Despite having some trouble with the ceramic coupons, the three products all removed over 85% of the Hucker's soil.
