There is nothing worse then having a horrible refrigerator odor. Many things can cause your refrigerator to have a bad smell such as leftovers, cut onions, mold, bacteria, and mildew growth. If you don't work to eliminate the refrigerator odor quickly, it can change the taste of all the food you have in it, and it's very unhealthy. Getting the smell under control is your main goal.
Avoiding Refrigerator Odor
To avoid odors, always keep baking soda in your refrigerator. Baking soda can absorb almost all smells and it is very easy to maintain, as you will only need to replace it every 3 months.
Make sure you have no expired food in your refrigerator. Food that is outdated can make you sick and also cause a foul smell that will ruin even your healthy food and can cause mold, bacteria, and mildew.
Sanitize your refrigerator. Keeping it clean and sanitized will keep a lot of the smells away. Using bleach or Lysol is the best way to sanitize.
Sometimes even after cleaning out the refrigerator, you can still have a bad smell that just won't go away. One thing you will want to do after sanitizing the refrigerator is to then wash it again with water and baking soda. Make sure you're cleaning out the drip tray under the refrigerator, because it can cause a lot of the bad smell. There are a few other things that you can do for those stronger smells, with just some basic things you may have around the home to help out.
Removing Tough Refrigerator Odor
Take a pan and put a layer of baking soda in the bottom of it which opens the baking soda up. This should help it absorb odors better. Turn the refrigerator off and leave the door open with the baking soda in it will also help air it out. You will need to have a way to store your food elsewhere while doing this.
Buy activated charcoal and lay it in a pan while running the refrigerator on low for a few days. This can also help eliminate the smell. Again, you will need somewhere else to store your food while doing this.
If this doesn't work, you can try putting cat litter in a pan and running the refrigerator on low for a few days to absorb the smell.
You can also take vanilla and put in a small dish and run the refrigerator for a few days or take fresh coffee grounds and leave them in the refrigerator for a few days.
If none of these common products removes the smell, the next step would be to get a commercial product to get the odors out. For the most part, one of these household items should take care of it and you should have a nice smelling refrigerator to store all of your fresh foods in again.
