Here’s a simple, expert-backed guide on how to sanitize your refrigerator properly, step by step.

6-Step Cleaning Guide to Sanitize the Refrigerator 

Keeping your refrigerator sanitized is essential for food safety and overall kitchen hygiene. Over time, spills, spoiled food, and hidden bacteria can lead to unpleasant odors and potential health risks. Whether it’s part of your regular cleaning routine or a deep clean after a spill, properly sanitizing the fridge ensures a fresh and germ-free environment for your food. Follow this 6-step cleaning guide to sanitize your refrigerator effectively and maintain a healthier kitchen.

Step 1: Empty and Prepare the Space

Start with a clean slate.
Remove all food items from your refrigerator. Check expiration dates and toss anything spoiled or questionable. Take out shelves, drawers, and other removable components so they can be washed separately.

Pro Tip: Store perishables in a cooler with ice packs while you clean to keep them safe.

Step 2: Wash with Hot, Soapy Water

Clean before you sanitize.
Use warm water mixed with dish soap to wash the inside of the fridge. Scrub shelves, drawers, and the interior walls, paying attention to corners and seals where crumbs and residue often collect.

• Wash removable parts in the sink.
  
• Wipe down the inside of the fridge with a sponge or soft cloth soaked in soapy water.
  
• Rinse surfaces with clean water and dry thoroughly with a clean towel.

Step 3: Sanitize with Bleach or Vinegar

Disinfect to kill bacteria and mold.

After the initial cleaning, it’s time to sanitize. You have two effective options:

• Option 1: Bleach Solution
  Mix 1 tablespoon of unscented liquid bleach with 1 gallon of water. Wipe down all interior surfaces with this solution using a clean cloth or sponge.
• Option 2: Natural Vinegar Solution
  Mix 1 part white vinegar with 2 parts water. This eco-friendly alternative helps disinfect and neutralize odors without harsh chemicals.

Important: Never mix bleach and vinegar together. Use one method at a time, and always rinse well afterward.

Step 4: Rinse and Dry

Finish strong with a thorough rinse.

After sanitizing, use a clean cloth dampened with plain water to wipe all surfaces again. This removes any residue from bleach or vinegar. Follow with a dry towel to remove moisture.

Step 5: Reassemble and Restock

Put everything back in place—cleaned and organized.

Dry shelves and drawers completely before placing them back into the refrigerator. Wipe down food containers and bottles before restocking them to avoid reintroducing grime or bacteria.

Step 6: Maintain Regularly

Consistency is key.

• Clean up spills immediately to prevent stains and odors.
  
• Check expiration dates weekly.
  
• Sanitize the fridge once a month or after any spills of raw meat, dairy, or other potentially hazardous items.
