20 Best Ways to Make Your Home Smell Amazing
Coffee absorbs unwanted odors
Ground coffee beans absorb odors in the air. They act as an odor absorber, signaling your brain that caffeine is on the way. While they do not absorb odors directly, they do neutralize some of the worst smelling foods and beverages. Because coffee beans absorb smells, they are best stored in an airtight container. This is particularly important if you plan on using them in the refrigerator.
In the refrigerator, coffee grounds are also a great deodorizer. If you want to neutralize the smell of spoiled foods, simply place a cup of coffee grounds in the bottom of the refrigerator. The aroma will stay for a few days, but if it persists, you can reuse the coffee grounds. Place a few coffee grounds in a glass or plate and place it near the odour source. This will help prevent the smell from coming back.
