Trial Number 2

Client Number 447

Project Number 1

Trial Purpose:

To evaluate the stability and effectiveness of Better Life Dish Soap against Seventh Generation dish liquid on the removal of Soil B from ceramic plates.

Date Run:

07/09/2019

Experiment Procedure:

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). 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 number of plates cleaned as well as the final temperature of the water in the basin were recorded. The process was repeated three times for each dish soap.

Trial Results:

Water Hardness: 24 mg/L CaCO3

Cleaner Initial Temperature (˚F) Final Temperature (˚F) # of Plates Washed Average Number of Plates
1 120 110 5 4.00
122 118 3
124 117 4
2 120 108 7 5.67
120 110 6
122 104 4

Success Rating:

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

Conclusion:

Better Life was not as effective as the comparative cleaner.
