1. Disinfection Solution: isopropanol (alcohol) concentration 70–80%;
2. Preparation: add 80 cc of 95% isopropanol (alcohol) to 20 cc of purified water (PURW) (or use the EPA
registered medical disinfectant wet wipes containing at least 70% isopropanol; all the appropriate safety
precautions and manufacturer’s instructions must be followed).
3. Use a piece of sterile gauze dipped in the alcohol mixture described above to wipe the surface of the
product for about 15 minutes (approximately once every 2 minutes). The isopropanol should be handled
according to appropriate safety procedures. The gauze should be moist without dripping because any liquid
may impair the electronics inside the product. Always pay close attention to the buttons, housing, slots and
gaps on the product. The sterile cotton swabs should be used for the disinfection in these areas.
