Trial Number 41

Trial Purpose:

To evaluate requested products on kitchen soil using manual cleaning

Date Run:

10/22/2007

Experiment Procedure:

The supplied cleaning products were used at full strength.
Preweighed fiberglass, ceramic and chrome coupons were coated with SSL Soil 4 (Ktichen Soil: Crisco Shortening 35%; Maxwell House Slow Roast Coffee, 1 tsp/4 oz 25%; Lipton The Brisk Tea, 1 bag/4 oz 25%; Garelick Farms Half and Half 5%; Synthetic Carpet Soil Mix 10%) using a hand held swab and allowed 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 WypAll X60 reinforced wipe was attached to the cleaning sled and soaked with 5-7 sprays of cleaning solutions. Each coupon was sprayed 7-10 times 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.

Trial Results:

All thirteen products had difficulty removing the kitchen soil from the various substrates in the allotted time. The table lists the amount of soil added, the amount remaining, the efficiency for each coupon cleaned and the average removal from each substrate type.
