Trial Number 7

Client Number 516

Project Number 1

Trial Purpose:

All-purpose test to determine the efficacy of the GeoPro X product in removing GS 34 standard production soil from a variety of substrates compared to other janitorial and industrial degreasing products. Rerun of previous test using a higher concentration of GeoPro X to see if the higher concentration leads to a higher efficacy.

Date Run:

04/30/2024

Experiment Procedure:

Three coupons of each substrate were used per cleaning product, for a total of 24 coupons.  Each coupon was weighed using a gravimetric balance and had their weights recorded.  Each coupon was then soiled with about 0.5 grams of GS 34 Production soil by using a swab to administer the contaminant down the center of the coupons.  The contaminated coupons were then left to dry for 24 hours.  After the 24 hour drying period, each coupon was weighed again, and had their 'dirty weights' recorded.  The coupons were then cleaned with their respective cleaning product using the Straight Line Washability Unit (or SLW) to ensure a standard pressure is applied to each coupon while being manually wiped.  Two sprays of the correct cleaner was applied to a wypall that is attached to the cleaning sled of the SLW to wipe the soil away and two sprays were applied directly to each coupon (meaning each coupon was cleaned with about 2.5 ml of cleaning chemistry).  The SLW unit was run for 20 cycles (20 back and forth motions) for each coupon.  Once cleaned, the coupons were allowed to air dry before having their final weights recorded.

Success Rating:

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

Conclusion:

All products performed comparatively and are highly effective in removing GS 34 standard production soil from Aluminum, Plastic, and Stainless Steel.
