Coffee is an Air Freshener
A few years ago, a friend of mine who drives a semi, was telling me about how they used to use coffee as an air freshener when hauling fish. He said they would literally throw bulk coffee beans into the back of the trailer with the fish, to help with the smell.Read: Coffee Beans in the Fish Truck
It's the same reason you don't want to keep coffee in the fridge or freezer. Coffee absorbs from the air around it, and the fridge is full of stuff.
[ad#Google Adsense - use me]I recently moved to the beach outside of San Diego, CA. Most of the apartments near the beach are, well...beachy. For instance, my building is at least 40 years old, and it looks it. Some of the cabinets throughout the apartment have an old smell, and I thought of coffee to do something about it.I've been traveling a lot recently and when I do, I tend to buy more coffee than I need from roasters in the cities I'm visiting. Long story short, I had way more coffee than I needed. Instead of throwing out coffee, I've been using it as an air freshener in old cabinets.That's my MacGyver trick for the week! :)
