SureTouch scales should handle blood exposure well, but lighter colors may stain over time. Regular cleaning with soap and water, followed by disinfecting, should help. Darker colors might be a better option if staining is a concern.wondering about using suretouch scales that will be exposed to blood as in a hunting knife application - i've been very satisfied with the customer response so far but haven't received any feedback regarding blood staining Sol-Guard Stain Repellent- anyone have any input ?
