Rubbing alcohol is neither an acid nor a base. Acids have pH values less than 7 and bases have pH values that are greater than 7. Rubbing alcohol has a pH value of 7, so it is neutral. Rubbing alcohol is also called isopropyl alcohol.
Iodine and hydrogen peroxide are both more powerful disinfectants than rubbing alcohol. Iodine is actually dissolved in alcohol when used as a disinfectant (which is called tincture of iodine) so you are getting alcohol anyway. Hydrogen peroxide is quite a potent disinfectant, however, it is also an unstable compound which will eventually give off oxygen and turn into ordinary water.
