Stopping the smell that is coming from your refrigerator involves first finding out exactly where the smell is originating. It could be coming from a container of food that has started to spoil. Likewise, mold or mildew could have built up on the inside of your refrigerator and the smell is a negative side effect. Whatever the reason, you can stop smells in your refrigerator in a few specific ways.
Go through your refrigerator and throw out any type of food that has been sitting around for too long. If you ordered Chinese food two weeks ago and haven't gotten around to eating it, it is likely contributing to the smell you're experiencing and needs to be disposed of. Throw out anything that's old and is no longer edible. Getting rid of the source of smells goes a long way toward getting rid of the smell itself.
