Trial Purpose:
To reevaluate products based on vendor requested dilution raises.
Date Run:
07/11/2003Experiment Procedure:
The supplied cleaning products were diluted with DI water for all purpose cleaning. 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.
Product Dilution Ratio
Envirox H2Orange2 128:1
Ecogent All Purpose 64:1
MD Stetson 101 Neutral 512:1
Trial Results:
The three products were all successful in removing the Hucker's soil from all three substrates. The table lists the amount of soil added and remaining for each coupon cleaned.
