Trial Report



Trial Number 2

(Client Number 341, Project Number 1)

Trial Purpose: To compare TMI Kitchen cleaner to alternative cleaners for kitchen soil cleaning.

Date Run: 12/21/10

Experiment Procedure:
Soil Preparation
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. Allow the soiled tiles to dry for 24 hours at room temperature.

Four sets of two coupons (Stainless Steel and Painted Steel) were initially weighed and recorded, then covered with DCC17 (Grease) using a hand held swab.

Cleaning Test
Place a soiled tile in the tray of the abrasion tester such that the direction of the soiling is perpendicular to the direction of the wiping media. Products were applied to the coated surfaces using a 3-5 sprays from manual spray pump and 4-7 sprays onto the reinforced Wypal X60 paper towel attached to the cleaning instrument. The cleaning was performed using Gardner Straightline washability unit and conducted for the prescribed 5 cycles (10 strokes). Following the initial cycle, if there was no discernable difference between the products and an additional 15 cycles were run.

Products were selected based on kitchen cleaning needs and health and safety options.

Trial Results
All four products were successful in removing the kitchen soil using manual wiping application. The table lists the amount of soil added, the amount
remaining and the efficiency for each coupon cleaned.
