How Do You Clean Smelly Birkenstock Sandals?
Kill bacteria and deodorize smelly Birkenstock sandals by sprinkling the sandals with baking soda and placing them in the freezer. Freezing kills bacteria, and baking soda neutralizes odors. Brush the sandals with a stiff brush to remove the baking soda.
-
Gather your materials
You need a gallon-size freezer bag, a fresh box of baking soda, a stiff-bristled brush and your sandals. You also need access to a freezer.
-
Sprinkle the Birkenstocks with baking soda
Sprinkle the foot beds and undersides of the straps with baking soda. Baking soda loses its potency over time, so start with a fresh box. Rub the baking soda into the straps with your fingers if necessary.
-
Seal the sandals in the freezer bag
Place the sandals into the freezer bag, and seal the top. If the sandals do not fit in the bag, wrap them in plastic wrap and heavy-duty foil.
-
Place the sandals in the freezer
Place the bagged or wrapped sandals in the freezer for at least two hours. Depending on the strength of the odor, they may need up to 24 hours in the freezer.
-
Remove the baking soda
Brush the foot beds and straps with a stiff brush to remove all of the baking soda.
