Nature produces special proteins called enzymes; they’re the single most effective odor neutralizer (antimicrobial) in existence. Formulated with these same natural, powerful enzymes, No Trace quickly eliminates the unnatural odors that repel catfish and other species. Spray directly onto hands, clothing or other surfaces to terminate odor molecules—including human pheromones, smoke, tobacco, gas, oil, insect repellant, sunscreen and other contaminants. No Trace also acts as a natural antiseptic and disinfectant. All natural, organic and completely safe for the environment.
