Orthotic devices, ranging from prefabricated shoe inserts to custom-molded arch supports, provide biomechanical correction and comfort. Because these devices are enclosed within shoes, they inevitably accumulate sweat, skin cells, and debris, creating an ideal environment for microbial growth. Regular cleaning is necessary to prevent the buildup of odor-causing bacteria and fungi, which can lead to skin irritation or infection. Maintaining the hygiene and structural integrity of orthotics ensures they continue to function correctly and provide the intended support for the foot.
Gathering Necessary Cleaning Materials
Preparation involves collecting a few common household items for a gentle yet effective wash. Use a mild cleaning agent, such as gentle dish soap or detergent, since stronger chemicals can damage surface materials or adhesives. Warm water is necessary for the cleaning solution, and a soft-bristled brush, like an old toothbrush, is useful for scrubbing. Before applying moisture, remove the orthotics from the footwear and use a dry cloth or brush to wipe away any loose dirt, dust, or hair that has collected on the surface. This simple step prevents loose debris from turning into muddy residue during the wet cleaning process.
The Standard Cleaning Procedure
Start the wet cleaning process by mixing a small amount of mild soap into a bowl of warm water to create a gentle, sudsy solution. Dip the soft brush into the mixture, ensuring it is damp but not saturated, and gently scrub the entire surface of the orthotic. Pay particular attention to the areas that make the most contact with the foot, such as the heel cup and the arch support, where sweat and dead skin cells tend to accumulate. After scrubbing, rinse the devices thoroughly under cool, running water to remove all traces of the soap solution. Avoid submerging or soaking the orthotics for extended periods, as excess moisture can weaken adhesive layers and cause the material to delaminate.
Specialized Treatment for Odor and Stains
Routine soap and water washing may not eliminate deeply embedded odors, which are often caused by bacteria converting sweat into smelly compounds like isovaleric acid. For persistent odors, baking soda acts as an effective deodorizer by neutralizing these acidic compounds and absorbing excess moisture. Lightly sprinkle the powder directly onto the orthotic surface and allow it to sit overnight before brushing it off in the morning. Alternatively, a diluted solution of one part white vinegar to one part water can be sprayed or wiped onto the surface, as vinegar possesses antimicrobial properties. For localized staining, a thick paste made from baking soda and a few drops of water can be gently rubbed onto the affected area to spot-treat the discoloration.
Proper Drying Techniques and Cleaning Frequency
After rinsing, immediately pat the orthotics down with a clean, dry towel to remove surface moisture. The devices must then be allowed to air dry completely in a well-ventilated area at room temperature. It is important to avoid using any source of direct heat, such as hair dryers, radiators, or direct sunlight. Exposing the orthotic materials to high temperatures can cause them to warp, shrink, or lose their custom-molded shape, compromising their effectiveness. Cleaning frequency depends on usage, but a light wipe-down should occur daily, and a deeper cleaning should be performed weekly or bi-weekly.
