How do I properly clean and maintain the Lyapko Insoles Plus 5.0 Ag to ensure hygiene and longevity?

Proper cleaning is essential for hygiene, especially since these insoles involve direct skin contact with metal components. The product features a medical rubber base and multi-metal needles composed of iron, copper, nickel, zinc, and silver. To clean them, use a soft cloth dampened with mild soapy water or a gentle disinfectant suitable for rubber and metals. Avoid harsh chemicals, bleach, or abrasive scrubbers, as these can degrade the rubber material or cause corrosion on the silver and other metal needles. After cleaning, rinse the surface with a clean, damp cloth to remove any soap residue, then dry thoroughly with a soft towel. It is crucial to allow the insoles to air dry completely in a well-ventilated area before storing them, as trapped moisture can promote bacterial growth or damage the adhesive layers if present. Do not submerge them in water for extended periods, and never use a washing machine or dishwasher. Regular maintenance ensures the needles remain effective and the rubber retains its flexibility. Store the insoles in a cool, dry place away from direct sunlight, which can degrade rubber over time. If you notice any significant wear, discoloration, or damage to the needles, discontinue use to prevent skin irritation or injury.
