Trial Number 1

Trial Purpose:

To test the efficacy of safer alternatives within the cleaning process for the Mash Tun. (Redo of previous testing)

Date Run:

11/20/2025

Experiment Procedure:

Three stainless steel coupons were assigned to each cleaner being tested.  The coupons had their initial weights recorded.  The coupons were then soiled with runoff from the Mash Tun by spreading 2ml of the runoff liquid on the bottom third of each coupon using a pipette.  The coupons were then baked in the oven for 2 hours at 170F to simulate the Mash in brewing process.  After the coupons were removed from the oven, they were weighed again and had their dirty weights recorded.  The coupons were then subjected to 20 mins of immersion in their respective cleaners with a stir bar set to 1,000 rpm to simulate agitation caused by CIP balls within the process.  After cleaning, each coupon was rinsed under a stream of tap water for 10 seconds to remove any potential residue from the cleaners.  After rinsing, the coupons were left to fully air dry before having their clean weights recorded.

Tested Cleaners:

A. Surface Cleanse 930 2% (Heated 130F)

B. EcoSafeway High pH Cleaner 5% (Unheated)

C. BevSafe CR 4.5% (Heated 120F)
