Logwood Trap Dye
This powered trap dye turns black when mixed with water, and turns traps a dark black color. I have found this dye to be as good as black dye and a lot cheaper. Instructions: In a container large enough to cover the amount of traps that you want to treat at a time - add 1 pound of red powder to each 5 gallons of boiling water and simmer for 1 hour. Add water as needed to keep traps completely covered. Remove traps - rinse with water - hang up to dry. Can be used on all steel traps.
