Packing peanuts can be reused for shipping purposes or dropped off at shipping stores to be recycled. But did you know that they can also help deodorize a refrigerator or musty drawer? If you want to get rid of a smell, fill a drawer or the compartments inside a refrigerator with packing peanuts. Let it sit for 24 hours to absorb odors. Remove the peanuts, and recycle them as you normally would. It really works!
