Over time, moisture from your feet or the ground can collect in the cork soles of Birkenstocks and cause ill effects like mold growth. The soles should be cleaned regularly to prevent any damage or unwanted smells.
To begin cleaning, dampen a brush or a wet cloth with mild soap or baking soda solution and scrub the cork footbeds in small, circular motions.
If the footbeds have stubborn stains, mix a bit of saddle soap with water and gently scrub. Allow the soles to air dry completely before wearing them again.
If there are any lingering smells after cleaning, try placing the Birkenstock sandals in a sealed plastic bag and leaving them in your freezer for up to 48 hours to kill any remaining mold or bacteria.
