If your cooler looks worse for wear after a long, active summer, don’t stress—there’s a simple fix! In this guide, you’ll learn how to clean a cooler that’s stained, has unpleasant odors, or is starting to develop mold—all with items commonly found at home. Follow these steps to extend your cooler’s lifespan and keep it in top condition.
Step 1: Create a Baking Soda Paste
Start by mixing one tablespoon of baking soda with one cup of water to make a paste. Baking soda acts as a gentle scrub that can help lift tough stains from the surface. The water helps spread the paste evenly while softening its intensity.
Baking soda is also a natural odor neutralizer, so it works well against musty or mildewy smells inside your cooler.
Step 2: Mix White Vinegar with Hot Water
White vinegar is an excellent all-purpose cleaner, especially effective on various surfaces like plastic and glass. Its acidity helps break down stains and eliminate odors. To clean your cooler with vinegar, fill it with hot water, then add one cup (240 ml) of white vinegar. Let it sit for a few minutes, then pour it out to disinfect and deodorize the interior.
If you’re using a spray bottle, set it to the widest spray setting for even coverage.
Step 3: Treat the Stained Areas
Spray the vinegar-water solution directly onto the stained parts of the cooler. For tougher spots, dissolve a tablespoon of baking soda in a cup of warm water and apply the mixture using a clean sponge or cloth. Let it sit for 15–20 minutes to allow the solution to break down the stains before scrubbing or rinsing it off with soapy water.
Step 4: Wipe Down with a Dry Cloth
Once the cleaning solution has had time to work, use a dry cloth or paper towel to wipe away any remaining residue. It’s important to remove all moisture before storing the cooler. For persistent stains, you can repeat the process or try alternatives like lemon juice or additional baking soda.
Step 5: Ensure the Cooler is Completely Dry Before Storage
Before packing your cooler away, make sure it’s completely dry—both inside and out. Storing a damp cooler can encourage mold or mildew to grow, especially in hidden corners and seams.
Final Thoughts
Understanding the cause of the stain or odor is essential for choosing the right cleaning method. If you’re dealing with mold or mildew, baking soda is ideal since it doesn’t leave behind a film like vinegar might. For grease or oil-based stains, consider using an enzyme cleaner for best results.
With just a few simple ingredients and a little effort, your cooler can look and smell fresh again—ready for your next adventure!
