Additionally, it should be kept in a sealed container that is tightly sealed to prevent evaporation. If isopropyl alcohol is stored properly, it can maintain its effectiveness for up to two years. If possible, isopropyl alcohol should be kept at room temperature, as this will help to extend its shelf life.

Question 3: Can isopropyl alcohol be used after it has expired?

Answer: Isopropyl alcohol should not be used after it has expired, as it will no longer be effective. Isopropyl alcohol that has expired will no longer contain the same level of active ingredients and may not be able to provide the same level of protection or cleaning as when it was fresh.
