Refrigerators are one of the most essential appliances in any home. Whether preventing food from spoiling and becoming unsafe to eat or keeping your favorite beverages cold and refreshing, your refrigerator is crucial to keeping your household running smoothly.

However, over time, dirt, debris, and bacteria can build up in the interior. Keeping your refrigerator clean and regularly maintained is essential to keeping your food safe and fresh. Unfortunately, many people are unsure about how often they should clean their refrigerators.

This blog post will explore general guidelines and tips to help you determine how often to clean your fridge and keep your food and family safe.

General Guidelines for Refrigerator Cleaning

How often should you clean your fridge? It depends on several factors, including the type of fridge you have and how often you use it. According to the U.S. Food and Drug Administration (FDA), regularly cleaning your refrigerator is crucial for food safety. They advise consumers to clean up spills and spoiled food immediately to prevent the growth of harmful bacteria.

Generally, it’s best to clean your refrigerator at least once every three months. This will help prevent the buildup of bacteria, dirt, and debris in the interior. However, this frequency can vary depending on several factors, such as the number of occupants in your household, your cooking habits, and the type of food you store in your fridge.

If you have a busy household with kids and pets or cook frequently and store various food items, you may need to clean your refrigerator more often. Additionally, if you meal prep or keep ready-to-eat items such as leftovers, sandwiches, or pre-packaged foods in your fridge, you should throw them away after three to four days.

Signs That Your Refrigerator Needs Cleaning

While cleaning your refrigerator every three months is a good starting point, sure signs indicate that it may need more frequent cleaning. Keep an eye out for the following indicators:

  • Foul Odors: If your refrigerator emits unpleasant odors after you remove expired food, it may be time for a deep clean. Lingering odors could indicate the presence of bacteria or mold.
  • Sticky Surfaces: Spills and stains left uncleaned can accumulate over time, leading to sticky surfaces inside your refrigerator. If you notice this issue, it’s a sign that your fridge needs a thorough cleaning.
  • Frost Buildup in Freezer: Excessive frost in your freezer can reduce its efficiency and affect the quality of frozen food. Regular defrosting and cleaning of the freezer compartment are necessary to maintain optimal performance.
  • Visible Mold or Mildew: Mold or mildew growth inside your refrigerator is a serious concern. If you notice any signs of mold or mildew, it’s crucial to clean and disinfect the affected areas immediately.

Cleaning the Interior of Your Refrigerator

Cleaning the interior of your refrigerator is a straightforward process that you can break down into simple steps:

  • Empty the Fridge: Start by removing all the food items from your refrigerator. This will allow you to access all the surfaces easily.
  • Remove Shelves and Drawers: Take out the removable shelves, drawers, and other detachable components from your refrigerator. Clean them separately using warm, soapy water.
  • Wipe Down Surfaces: Use a mixture of mild detergent and warm water to wipe down your fridge’s interior walls, shelves, and drawers. Pay extra attention to any areas with spills or stains.
  • Clean the Door Gaskets: The rubber door gaskets can accumulate dirt and grime over time. Wipe them thoroughly using a cloth dipped in a water and vinegar solution.
  • Replace Food and Organize: Place the food items back into the refrigerator once the interior is clean and dry. Take the opportunity to organize your fridge, discarding expired or spoiled items.

Cleaning the Refrigerator Water Dispenser

If your refrigerator has a water dispenser, it requires additional attention to ensure cleanliness and prevent the growth of bacteria. Here’s how to clean the water dispenser:

  • Check the Manufacturer’s Instructions: Refer to your refrigerator’s user manual to find specific instructions for cleaning the water dispenser. Different models may have various requirements.
  • Turn Off the Water Supply: Before cleaning, turn off the water supply to the dispenser to prevent any leaks or spills.
  • Remove and Clean the Dispenser Tray: Take out the drip tray from beneath the water dispenser and wash it with warm, soapy water. Dry it thoroughly before placing it back.
  • Flush the System: Dispense a few cups of water from the dispenser to flush out any residue or impurities. This will ensure that you have clean, fresh water for consumption.

How Often To Clean Your Refrigerator Depending on Your Lifestyle

While the general recommendation is to clean your refrigerator every three months, your lifestyle and habits may require more frequent cleaning. Consider the following factors to determine the appropriate cleaning frequency for your fridge:

  • Family Size: Larger households with more people tend to use refrigerators more frequently, leading to increased spills and messes. If you have a big family with children, you may need to clean your fridge more often to keep it hygienic and organized.
  • Cooking Frequency: The more you cook, the more spills and food residues can accumulate in your refrigerator. If you’re a frequent home chef, clean your fridge every month or two to keep it fresh and odor-free.
  • Food Storage Habits: You must clean your fridge more frequently if you often store perishable foods like raw meats and seafood. These items can release juices and create a breeding ground for bacteria.

Remember, these are general guidelines, and it’s crucial to assess the condition of your refrigerator regularly and adjust the cleaning frequency as needed.


Cleaning your refrigerator regularly is vital for maintaining food safety, preventing odors, and ensuring the efficient functioning of your appliance. While cleaning every three months is a good rule of thumb, factors such as family size, cooking frequency, and food storage habits can influence how often you clean your fridge.

By staying proactive and paying attention to signs of dirt, odors, and spills, you can determine the appropriate cleaning frequency for your refrigerator. Remember to follow the manufacturer’s instructions for cleaning specific parts of your fridge, such as the water dispenser, and always prioritize food safety and hygiene.
