Trial Purpose:

To evaluate three supplied products for all purpose cleaning following GS 37 requirements

Date Run:

09/04/2014

Experiment Procedure:

Preweighed ceramic, plastic G-10 and painted steel coupons were coated with Hucker's Soil Formulation (Jif Creamy Peanut Butter,Salted Butter, Arrowhead Mills stone ground wheat flour, Egg Yolk, Evaporated milk, distilled water, Printer's ink with boiled linseed oil, Shaws saline solution) 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. A Kimberly-Clark Wypal reinforced paper towel was attached to the cleaning sled and soaked with 1 spray of cleaning solution. Each coupon was sprayed once 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.

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion:

All Purpose Regular and Heavy-Duty Degreaser were both effective at removing Hucker’s Soil. A cleaner is effective with a cleaning efficiency rating of 85% or higher.  Heavy Duty Degreaser was the most effective at removing Painted Steel, Plastic and Ceramic coupons. However, All Purpose Gel overall may not be effective at cleaning all sorts of coupons; it is nonetheless effective at removing Plastic coupons.
