Project Number 1

Trial Purpose:

To evaluate the supplied product for all purpose cleaning

Date Run:

04/27/2015

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.

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 1 time with the same cleaning solution. The cleaning unit was run for 20 cycles (~33 seconds). Final weights were recorded, efficiencies were calculated and recorded.

Summary Table:

Cleaner: % Avg. Removed
E-50 81.4
Forumla 409 86.2
Water  79.5

Success Rating:

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

Conclusion:

The most effective cleaner was Formula 409. It had a rating of 86.2%. In addition to that E-50 had a rating of 81.4% removal rate. Even though E-50 was not considered to be an effective cleaner, it was still partially effective at removing most of the soil from the substrate. For all three cleaners, plastic substrates had the most contaminant removed from its surface.  Overall, the best cleaner at removing grease soil contaminant from its surface is in the order of Formula 409, E-50 and Water.
