■ Overview Waders and wading shoes worn during fishing trips are simply rinsed with tap water and left to dry... If you treat them in a way that's far from proper maintenance, the inside of the fabric will fall into a poor hygienic state. By the time your car smells bad enough for passengers to complain, "It smells awful...", you'll likely realize the source of the unbearable stench. There's a reason for that foul odor. The smell is caused by bacteria and Moraxella bacteria, which thrive on the "unremoved substances" mentioned above, due to the wet lining of the waders remaining damp, or the secretions from sweat glands and sebaceous glands inside the waders not being completely removed. ■ Eliminating the Odor Spraying a deodorizer inside the waders is only a temporary solution. Febreze, for example, only encapsulates the odor with deodorizing molecules derived from corn, so spraying deodorizer is just "symptomatic treatment" unless you eliminate the source of the odor. ※ Even if you attach a car-specific Febreze to the air conditioning vents in your car, it won't deodorize if the filter in the air intake of the air conditioner in the engine room is covered in mold; it's just masking the smell with fragrance. Sterilizing by turning the waders inside out and exposing them to direct sunlight is also not recommended. The representative breathable waterproof fabric used in waders, "GORE-TEX," is made by sandwiching a single Gore-Tex membrane film between nylon fabrics on the front and back. Exposing nylon materials to direct sunlight is a mistake, as it accelerates chemical degradation due to heat and ultraviolet rays. While you may see suggestions to use "Wide Haiter EX" for deodorizing, the "seam parts" that join the fabric to shape the waders three-dimensionally have very delicate waterproofing. Using chlorine-based detergents or plant-derived fermented alcohol components can damage the seam tape, causing it to peel off, which is counterproductive. After washing the waders with detergent, if the insoles of the boots are damp and in a "half-dry" environment, the odor-causing bacteria will multiply explosively, making the problem even worse. ■ So, what should you do? The most effective method is to perform "causal therapy" to eradicate the odor-causing bacteria that are the source of the smell. This product uses the action of natural enzymes and BB bacteria to kill the odor-causing bacteria.
