Keeping your fridge clean and mold-free is essential to keeping your food fresh. You can ensure the safety of your family and the freshness of your food by checking your refrigerator for any signs of mold.

If you keep all of your leftovers in the fridge, it’s possible that some of them will rot and grow mold. If you don’t keep an eye on the food in your fridge, you may not notice if molds have already started to grow.

There is a lot of moisture in the fridge, which makes it ideal for the growth of mold.

Why Is My Refrigerator Moldy?

Spoiled Food

Food that is decaying or decomposing is the most common cause of refrigerator mold. Mold can easily spread via the air and contaminate surfaces such as shelves, doors, and rubberized sections of door seals, even if you only discard a few ruined things. Your refrigerator has all of these items. Because you’ve thrown out the moldy cheese, it doesn’t mean that you’re completely free of mold and contamination.

Getting Rid of Mold

Cleaning your fridge is a rather straightforward task. Deep cleaning isn’t always possible, but you can still use household objects for the job.

In order to properly maintain your refrigerator, follow these steps:

  1. Remove all of the shelves and removable drawers from your refrigerator, if it has any.
  2. Vinegar can be used to clean them. Vinegar should not be diluted, as diluted vinegar will not kill mold effectively.
  3. While the vinegar takes effect, leave the shelves and drawers out of the way for a moment.
  4. Spray the interior of the refrigerator, focusing on the seals within the door, the cracks inside the hinges, and any extra shelf units that may be there (particularly the shelving on the inside of the door). Smaller spots may still be harboring mold, so be very vigilant.
  5. Wet a rag and scrub all of these surfaces.
  6. Clean and dampen a new cloth and wipe the surface again.
  7. All surfaces should be thoroughly sanitized. This can be done as many times as necessary.
  8. Discard all of the paper towels in your home.
  9. Disinfect the refrigerator by rinsing all of the damp rags and towels you used to clean it. Use a mixture of hot water and detergent.

Additional Tips

  • Mold can be easily removed from the rubber seal of the door by mixing one part water with one tablespoon of chlorine bleach. In addition, you can use one part baking soda or one part lemon for an even more thorough cleaning process.
  • Mold killer and disinfectant can be used instead of vinegar if you don’t have any on hand.

Preventing Refrigerator Mold from Returning

You can prevent mold in your fridge by doing the following:

  • Don’t let your food spoil by not eating it as soon as possible. Meats, cheeses, and even milk can be frozen for bacteria prevention if you don’t have time to eat them all.
  • If food has beyond its expiration date, throw it away.
  • Mold-prone items, such as cheeses, fruits, and vegetables, should be watched closely to avoid contamination.
  • Use plastic wrap, tin foil, or a food-safe plastic container to store food in the refrigerator. This is the best approach to keep mold from growing on surfaces inside and outside of the refrigerator.
  • Repeat the above cleaning steps. Do this once a month at the very latest.
