Trial Purpose:
To evaluate effectiveness of the provided cleaners in regards to removing synthetic blood from stainless steel.
Date Run:
02/05/2018Experiment Procedure:
Twelve 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. Two additional coupons were weighed but not soiled to provide a control. Two cleaners were prepared using the specified dilutions and temperature: Biogone (RTU at 22 C); Biogone (1:1 at 22 C).
Six coupons per cleaner were immersed in a beaker for two minutes. Coupons were rinsed in a de-ionized water bath for one minute and dried for 28 hours before recording clean weights.
Trial Results:
Both dilutions of Biogone were effective at removing the synthetic blood from the stainless-steel coupons.

Success Rating:
A cleanliness study, addressing only various analytical techniques.Conclusion:
Both dilutions of Biogone were effective, as an overall average removal of 85% or more is considered effective. The RTU dilution was about 1% more effective than the 1:1 dilution. The product diluted 1:2 removed slightly more than 65%. The results were verified with visual observations.
