I have some traps in the attic that have been there for a quite a few years. They have been dyed and waxed, and only used one season. However, being above the garage, I am concerned that they have picked up the odors of gasoline, exhaust fumes, gardening chemicals, ect. What is the best way to clean these traps, and how can I keep them odor free until season? Thanks in advance. Wanna kill these ads? We can help!
