Trial Number 3

Client Number 513

Project Number 1

Trial Purpose:

To test the effectiveness of Green Mountain Ammenities all purpose cleaner against other all purpose cleaners on the market.

Date Run:

09/27/2023

Experiment Procedure:

Eighteen coupons per cleaner, three of each substrate, were used.  The initial weights of each coupon were taken.  The initial L value (measure of flurorescence) was also taken with the colorimeter.  The coupons were contaminated with DCC-17 Formulation using a handheld swab and dried overnight. The contaminated coupons were weighed and the dirty L value was measured before placing three coupons per cleaner of the same substrate into a Gardner Straight Line Washability (SLW) unit. A Kimberly-Clark Wypal reinforced paper towel was attached to the cleaning sled. The Wypal and each coupon were treated with three sprays and cleaned for 20 cycles (~30 seconds of cleaning). Clean coupons dried for 24 hours before final weights were taken to asses the amount of soil removed. The final L value was taken in order to asses the amount of staining left behind by the soil.

Colorimeter

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 GMA D Limonene cleaner performs comparatively to the other tested cleaners in removing soil.  It is a somewhat effective cleaner.  However, it performed the worst out of all the cleaners in removing staining (removed staining from paint steel, but not VCT).  It is not effective in removing staining.
