Trial Number 3

Client Number 230

Project Number 1

Trial Purpose:

To evaluate biobased products for cleaning toilet bowls

Date Run:

10/26/2004

Experiment Procedure:

Six products were selected from the lab's inventory of biobased cleaning products. The client's current product was also included for comparative purposes. Five of the products were diluted with water to the vendor-recommended concentration. Pre-weighed coupons of ceramic (3) and plastic were coated with a diluted Hucker’s Soil and allowed to dry overnight at ambient temperature. The contaminated coupons were weighed using a Denver Instrument Model A-250 analytical balance to determine the amount of soil added (i.e., initial weight).

The coupons were placed in a Gardner Straight Line Washability unit, as referenced in ASTM International (formerly the American Society for Testing and Materials) standards and by CSPA, the Consumer Specialty Products Association’s (formerly CSMA) detergent compendium. 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 cleaning unit was run for 20 cycles (approx. 33 seconds). The coupons were wiped once with a dry paper towel. Gravimetric weights were recorded once more, from which the remaining soil (i.e., final weight) can be determined.

Trial Results:

Nearly all of the products tested removed over 80% of the diluted Hucker's soil from the two substrates. The table list the amount of soil added, the amount remaining and the percent removed for each coupon.

Conclusion:

Four products tested averaged 85% removal of the soil from the two substrates.
