A combination of your body chemistry and the rubber used on the top sole may be causing an unpleasant odour to emanate from your Teva sandals, according to Teva.com. Fortunately, you don't have to live with the smell. While you may have to deodorise your sandals routinely, you can banish the unappealing scent for at least a few weeks at a time.
Bend the heel of the sandal backward, toward the toe of the sandal and spray off with a sprayer attachment connected to a sink, bathtub or garden hose. This will remove any dirt present in the grooves of the foot bed of the sandal.
Bend the sandal, again, as you did in Step 1, and scrub the top sole with a soft-bristle brush and a mild antibacterial soap. Rinse thoroughly.
Pour 1 part antibacterial mouthwash to 2 parts of water in a pan or container large enough to soak the sandals. Pour enough mouthwash and water to cover the foot beds of the sandals. It is not necessary to submerge the straps.
Soak the sandals in the mouthwash and water solution for approximately 15 minutes, and scrub the top soles with a hard-bristled brush.
Allow the sandals to air dry in a well-ventilated area, out of the direct sun, before wearing.
Teva.com recommends that you clean your sandals every two to three weeks to reduce the build-up of bacteria. If your sandals are leather, clean with a leather nubuck cleaner. Clean the top soles as indicated in Step 2, and allow the sandals to dry in a well-ventilated area out of direct sunlight.
Don't scrub the nylon or leather straps on Teva sandals as it can cause them to fray or become otherwise damaged.
