To evaluate three supplied products for all purpose cleaning following GS 37 requirements
The submitted cleaning products were diluted with cool DI water to vendor recommended concentration for all purpose cleaning.
Preweighed ceramic, plastic G-10 and painted steel coupons were coated with a mixture of three cooking oils/greases was made. A melt blend of 33% vegetable shortening, 33% lard, 33% vegetable oil and 1% carbon lampblack was made up fresh for the testing. Care was taken in the application of the soil onto the coupons so that light and heavy areas were avoided. The soiled tiles were allowed to dry for 24 hours at room temperature. Gravimetric readings were made for each of soiled tiles.
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.
ChemistriesEvaluated: Multipurpose 1:16; Multipurpose HC 1:25.6; H2O2 Tile Grout HC 1:25.6; Proforce MC Pine_ceramic
All three products were effective at removing the soil from the three surfaces using manual wiping. The Product 1 resulted in the lowest efficiency, removing around 90% of the soil. The table lists the amount of soil added, the amount remaining after cleaning and the calculated efficiency for each coupon cleaned.

Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
The three submitted products were found to be effective at removing the grease soil mix from various surfaces using manual wiping. They compared well to the comparative cleaning product used for testing.
