How long does rubbing alcohol remain effective after expiration date?

Rubbing alcohol can remain effective for a period of time after its expiration date, typically ranging from a few months to a couple of years, depending on storage conditions and its concentration. However, its antibacterial properties may diminish over time, especially if it has been opened or improperly stored. For best results, it's advisable to replace expired rubbing alcohol to ensure optimal effectiveness. Always check for changes in appearance or odor before use.
