I had to try this one to believe it. You can use fresh coffee grounds to remove tough odors from just about anything. I first heard about this as a method for removing cigarette smells from furniture. If it can do that, it can do anything. Anyone who has ever received remainder furniture from a smoker knows how difficult it is to remove the smell. To remove odors from furniture, place the furniture inside a large furniture bag with a plate covered with fresh coffee grounds. Seal, and let it sit for a few days. Remove the furniture and the grounds and the smells are gone. Coffee grounds will also remove bad odors from fridges.
