Trial Purpose:
To evaluate effectiveness of the provided cleaners in regards to removing synthetic blood from stainless steel.
Date Run:
10/26/2017Experiment Procedure:
Fifteen pre-weighed stainless steel coupons were soiled with synthetic blood using a swab, and allowed to air dry for 24 hours before recording dirty weights. Five cleaners were prepared using the specified dilutions and temperature: Super Nova.1 NpHD (0.8ml/1L at 160F), Biogone (33% dilution at room temperature 68 F), Pentazyme (0.5 oz/gal at 140 F), and PentaPrep Spray (RTU at 140 F). Three coupons per cleaner were immersed in a beaker for two minutes except for Biogone, which had a three-minute contact time. Coupons were rinsed in a DI water bath and dried for 24 hours before recording clean weights.

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 PentaPrep Spray and Super Nova. 1 NpHD were the only two products effective at removing synthetic blood off stainless steel.
