The little nipple i rub on my MightyMouse is losing its sensitivity. I've been using a Q-tip lightly dampened with alcohol to clean it and I think it's become addicted to alcohol Whereas I started having to clean it a couple times a week, it's gradually progressed to about once an hour. My hands aren't the sweaty type and I don't use lotion on them. I drink a lot of coffee so i wash my hands about every hour. I have come to the conclusion that alcohol is bad for my nipple. What do you use to clean your nipple?
