Project Number 2

Trial Purpose:

To compare the efficacy of Enzo NRF enzyme cleaner at two different temperatures (90F vs 130F)

Date Run:

03/06/2024

Experiment Procedure:

Six stainless steel coupons were used, three to be cleaned at 90 F and three to be cleaned at 130 F.  The initial weights of each coupon were taken.  The coupons were then soiled with Cedar's Chocolate Hommus by wiping a thin layer, but leaving some chunky spots, on the bottom half of the substrate.  A heat gun was applied to each coupon at its highest temperature for 2 mins each to mimic the pasteurization process that happens within the mixing tanks, allowing the soil to better adhere to the coupons.  After the coupons cooled, their dirty weights were taken.  The coupons were then subjected to 10 minutes of heated ultrasonics (three at 90 F and three at 130F) using the Enzo NRF enzymatic cleaner at a 2% dilution.  The coupons were then removed and allowed to air dry before the clean weights were taken.

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 Enzo NRF Enzymatic Cleaner at 2% dilution had effectively the same efficacy at both 90 F and 130 F.
