How do I clean and disinfect my rechargeable pulse oximeter without damaging it?
Use 70% isopropyl alcohol wipes on the exterior and sensor window, avoiding the charging port. For thorough cleaning, slightly dampen a microfiber cloth with alcohol—never spray liquids directly onto the device. Allow complete drying before charging. Some models have removable sensor covers that can be washed with mild soap and water. Avoid harsh chemicals like bleach, which can degrade sensors and housing materials. Clean at least weekly with daily use, or after any illness.
