The neffy® trainer must be cleaned if it has been put in a person’s nose. This will reduce the chance of spreading infection. It should be wiped with 70% isopropyl alcohol. Allow the alcohol to dry before putting the neffy® trainer in the nose to avoid irritation.
If you are concerned about spreading infection from nose to nose when using the neffy® trainer, you may choose to put the neffy® trainer on the outside of the nose instead. Make sure you still point the neffy® trainer in the correct direction. Remember when using the real neffy® it must be inserted into the nose.
