In fact, isopropyl alcohol has a very low boiling point, which is why it is often used in things like cleaning products and hand sanitizers. Why Does Isopropyl Alcohol Evaporate So Quickly When Drinking? Its a common misconception that alcohol evaporates quickly. However, it also has a high freezing point, so it can be difficult to remove from surfaces. This is because the water molecules are attracted to the dissolved salt ions and it requires more energy to break apart those water molecules for them to evaporate. This is simply not true. Is there a faster method to make the alcohol evaporate?

This is because it has a very low boiling point, meaning that it turns into a gas at relatively low temperatures. The process of changing a liquid into its gaseous state is called evaporation. Fill a spray bottle with the diluted solution (use a 1:1 ratio of water and denatured alcohol) and spray it on the glass surface of your choice. Do the experiment: spill two samples of $5~\mathrm{ml}$ simultaneously, blow onto one of the two and check how much quicker it evaporates. According to the blog post, it takes rubbing alcohol about an hour to evaporate completely. It is also known as isopropyl alcohol or IPA. The model above ignores complicating factors like mean free path, the fact that evaporation is endothermic (meaning the liquid cools as it evaporates and the vapor pressure decreases with time), the temperature and heat capacity of the surface govern how much kinetic energy is available to the liquid to begin with, and that any amount of air current in the vicinity will move the vapor away significantly faster than diffusion.
