Trial Purpose:
Evaluate the efficacy of Client's cleaner formulations on the removal of synthetic blood soil from a stainless steel substrate.
Date Run:
02/10/2026Experiment Procedure:
15 pre-weighed stainless-steel coupons were coated with synthetic blood using a swab and were allowed to air dry (68 F) for 24 hours. The supplied cleaner concentrates were then diluted by a ratio of 0.5 oz/ gallon of water. Dirty weights were then recorded. The contaminated coupons were immersed in their respective cleaner at room temperature for two minutes. Following immersion, coupons were rinsed three times in a de-ionized water bath for one minute and dried for 24 hours before the final weights were recorded.

Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.Conclusion:
Based on the results of this report, Caseprep and Supernova 1.0 were the most effective at removing the blood soil from the substrate, but all cleaners attained a high level of cleanliness (>80% removal) and as such can all be considered effective in the cleaning application.
