This is my deodorizing trick. I put coffee beans on vase and have it on our kitchen counter near the stove and also by the sink counter. It helps eliminates odor from cooking especially the strong fish odor. We love to fry fish once a week during Sundays. It is proven in my case because our home does not smell bad. Well our home is well ventilated but the coffee beans help absorb the bad smell faster and keep your home fresh.
