Things You'll Need
Orange Igloo coolers have long been used for sports games and also by construction workers and similar occupations when you want a high visibility cooler. Since coolers are designed to insulate, they are tightly sealed and therefore also can hold in moisture and odor as well as encourage mold or mildew growth if the unit is not properly cared for. When cleaning, use mild and non-toxic cleaning agents that remove buildup from the Igloo cooler without requiring harmful chemicals.
Empty the cooler and rinse the cooler with warm water.
Drizzle a light coat of dish soap over a wet cleaning rag and scrub down the inside of the Igloo cooler. Flush the soapy water out through the spout when applicable to clean this area as well.
Sprinkle a thick coat of baking soda onto a clean rag and scrub over any stained areas. Continue until all stain residue is removed.
Rinse out the cooler thoroughly and drain the water out through the spout.
Let the cooler air dry completely before putting the lid back onto the cooler and before storing it. Trapping moisture inside can lead to mildew growth.
