5. Nose Bulbs

Nose bulbs can get mold growing inside of them if they aren’t sterilized properly at least once every two months. Wash the bulb inside and out with a mild soap and hot water. Allow to air dry, and then boil it for five minutes. Air dry once more, and finally, rub the outside with rubbing alcohol. You could swish a little rubbing alcohol inside as well if you wish.
