Three pre-weighed stainless-steel coupons were coated with synthetic blood using a swab and allowed to air dry (68 F) for 24 hours. Dirty weights were recorded before immersing coupons into the RTU cleaner provided by the company at room temperature (68 F) for two minutes. Coupons were rinsed three times in a de-ionized water bath for one minute and dried for 24 hours before recording the final weights.
