Crocs and other rubber sandals keep your feet cool in the summer, but if you practically live in them during the warm months, they can start to smell and look dirty. Give your rubber shoes a thorough cleaning to get rid of the dirt and grime and then hit them with an odor-fighting duo -- vinegar and baking soda -- to deodorize them.
Get the Dirt Out
Crocs and rubber sandals should be washed by hand, not in a machine. Fill a bucket with cool water and a squirt of mild dish soap. Mix it up well. Wipe the shoes with a rag and the soapy water until they are clean. Use a toothbrush and the soapy water to get in the vent holes of the shoes or any other hard-to-reach places. Rinse the shoes off under cool running water and then dry thoroughly with a towel.
Banish Unpleasant Odors
If your rubber sandals start to smell, cleaning with soap and water might not be strong enough to deodorize them. For fresh-smelling shoes, apply a paste of baking soda and vinegar -- three parts vinegar to one part baking soda. Spread the baking soda paste onto the inside of the shoes. Wait for five minutes and then soak them in a bucket of cool water for about three hours. Scrub the inside of the shoes with a toothbrush; rinse and dry well.
