To evaluate the effectiveness of the provided cleaners in regards to removing synthetic blood from stainless steel.
36 pre-weighed stainless-steel coupons were coated with synthetic blood using a swab and were allowed to air dry (68 F) for 24 hours. One set of 18 coupons was set aside for the cleaner SuperNova 0.1 NpHD Neutral Detergent and the other set of 18 coupons was set aside for SuperNova 0.1 Multi-Enzymatic cleaner. Dirty weights were then recorded. The contaminated coupons were immersed in their respective cleaner in sets of three at a temperature of 160 F for SuperNova NpHD for two minutes and 140 F for SuperNova Multi-Enzymatic 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.
