Trial Number 3

Trial Purpose:

To evaluate supplied product on kitchen soil

Date Run:


Experiment Procedure:

The supplied cleaning product was used at the supplied concentration. A second product, selected by the lab, was diluted with DI water to vendor recommended dilution (2.6) for general purpose cleaning.

Six preweighed ceramic were coated with SSL Soil 4 (Kitchen 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% and 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. Photographs of the dirty coupons were taken.

Three coupons were placed into a Gardner Straight Line Washability unit. A Professional Painter's Rag 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 solution was allowed to penetrate for 30 seconds followed by cleaning in the SLW unit for 20 cycles (~33 seconds). At the end of the cleaning, coupons were wiped once with a dry paper towel. Final weights were recorded and cleaned coupons were photographed. Efficiencies were calculated and recorded.

Trial Results:

Both products were not effective in removing the soil with a manual wiping action. The table lists the amount of soil initially added and the amount remaining after cleaning and the product efficiency for each coupon cleaned. Dirty and clean pictures are also provided below. Longer cleaning times would benefit both products for this soil.
