Trial Purpose:

Benchmark testing of ICT 1648L for Craft Beverage project.

Date Run:

06/24/2024

Experiment Procedure:

Three pre weighed coupons of each substrate, plastic and stainless steel, were used per soil for a total of 12 coupons per cleaner concentration tested.  Half of the coupons were soiled with tea and tea leaves with a swab.  The other half were soiled with coffee and coffee grounds with a swab.  The coupons were then baked in the oven or 40 minutes at a temperature of 200 F to adhere the soils to the coupons and to initiate staining.  The dirty weights of the coupons and visual rankings were then recorded. The coupons were then subjected to 10 minutes of unheated immersion in their respective cleaners with a stir bar set to 300 rpm.  The cleaner was used at the vendor recommended concentrations (2% and 1%) .  The coupons were then removed from the cleaner and the clean visual rankings were recorded.  The coupons were allowed to dry overnight before clean weights were recorded.  Visual rankings were based on the key below.

Visual Rankings

1= 100% soil removed

2= 75% soil removed

3= 50% soil removed

4= 25% soil removed

5= 0% soil removed

Although both concentrations of the ICT cleaner were able to remove upwards of 90% of the weight of the coffee soil, there was a substantial amount of staining left from the coffee on the coupons after cleaning.

Success Rating:

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

Conclusion:

Both ICT 1648L at 2% and ICT 1648L at 1% were highly successful in removing both tea leaves and coffee grounds from stainless steel and plastic.  The two concentrations performed equally.
