Homemade Blood Tracking Spray
Does anyone have a "recipe" for a spray to aid spotting blood?
Below is one I have seen before:
To determine whether a tiny drop of blood you’ve spotted really is blood, spray it with a homemade concoction of two parts water and one part hydrogen peroxide. Any blood hit by the spray will foam up slightly. The spray even works on old blood and shows up well under the light of a flashlight or, better yet, a Coleman gas lantern.
Also saw one that called for 75% HP and 25% water with some yellow food coloring added.
Has anyone use either or have a different one that will aid someone who is red/green color blind?
Thanks for the help.
