Trial #3
To evaluate the stability and effectiveness of L'AVANT Collective Dish Soap against Dawn Dish Soap on the removal of Soil B from ceramic plates.
Pre-weighed clean ceramic plates were soiled with six grams of 4009 Soil B (50% All Purpose Flour, 48% Crisco Shortening, and 2% Olive Oil) and air dried for 24 hours at room temperature (68 ̊F). After drying, each soiled ceramic plate were weighed to determine contaminated weights. Four millimeters of each dish soap were measured out and each were mixed with four liters of tap water heated to 120°F, which was recorded when poured sequentially into the washing basin. Twenty seconds after the reservoir was prepared, the manual cleaning method began. Each plate was washed at an angle, half submerged in the water, cleaning both the front and back sides of each plate with a sponge in a circular motion for 30 seconds. This process continued until half the surface of the wash solution showed a thin layer of foam. The plates were allowed to air dry after washing. Once air dried, each plate was weighed to determine clean weights for gravimetric analysis.
