Learn how to clean your soft cooler, remove odors, and dry it properly to extend its life. Step-by-step guide for CORE coolers.

Quick Answer

To clean a soft cooler, empty it, hand-wash the interior with mild soap and warm water, rinse thoroughly, and air-dry it completely with the lid open to prevent mold and odors.

Why Regular Cleaning Matters

Soft coolers trap moisture and food residue, which can lead to mildew, stains, and lingering smells. A quick clean after each trip keeps the lining fresh and the insulation effective.

Magnetic closures like the MagSnap® on the CLIMAKEEP 36 Can Magnetic Soft Cooler need occasional attention too—crumbs and sticky spills can interfere with the seal.

What Not to Use

Avoid bleach, harsh chemicals, and abrasive scrubbers—they can damage the waterproof coating and fabric. Stick to mild dish soap or a vinegar solution for stubborn odors.

Step-by-Step Cleaning Process

Empty and Shake Out Debris: Remove all contents, including any leftover ice or water. Turn the cooler upside down and shake out crumbs or dirt. Check pockets and corners. Skipping this step can leave food particles that cause odors during washing.
Hand-Wash the Interior and Exterior: Mix a few drops of mild dish soap with warm water. Use a soft cloth or sponge to gently scrub the inside lining, the magnetic closure strip, and the outside fabric. Rinse with clean water. Do not submerge the cooler fully—water can get trapped in the insulation layer.
Remove Stubborn Odors: For lingering smells, mix one part white vinegar with two parts water. Wipe down the interior and let it sit for 10 minutes before rinsing. Baking soda paste also works on stains. Test any solution on a small hidden area first to confirm it won't discolor the fabric.
Dry Completely Before Storing: Wipe excess moisture from the interior with a clean towel. Leave the cooler open in a well-ventilated area away from direct sunlight for at least 24 hours. Make sure the magnetic seal and zippers are dry too. Storing a damp cooler is the most common cause of mildew. Wait until every surface feels dry to the touch.
