When your Crocs start to smell it's time to kick the odor to the curb. Although Crocs are made from a material that is anti-microbial, which helps to keep odors at bay, this doesn’t mean that the shoes will smell fresh forever. The good news is you don’t have to ditch your Crocs for a new pair, just deodorize so they smell fresh again.
Fill a bucket with cold water. Add a squirt of dish soap and mix up the water with your hands.
Put the Crocs in the soapy water. Scrub the insides of the shoes with a rag and the soapy water.
Rinse the Crocs well with clean water. Dry them completely with a towel.
Pour baking soda into the inside of each Croc so the bottom of the shoe is completely covered. Lay the shoes flat in a plastic bag so the baking soda doesn’t spill out and tie up the bag. Put the bag in the freezer overnight. Shake out the baking soda the next day.
Stuff newspaper inside your Crocs after you take them out of the freezer. Leave the paper in for a few hours to absorb any remaining odor.
