What Happens if you Use Expired Rubbing Alcohol?

If you use expired rubbing alcohol it can reduce disinfection effectiveness, as its alcohol content may have diminished over time. The chemical composition may also change, potentially leading to the formation of impurities or byproducts that could be unsafe for use on skin or surfaces. 

Additionally, an expired bottle may have been exposed to environmental contaminants and may not provide the cleanliness or germ-killing capability needed for critical tasks. It is generally advisable to prioritize using unexpired rubbing alcohol for effective and safe disinfection.

Things that Happens if You Use Expired Rubbing Alcohol

Using expired rubbing alcohol can have various consequences depending on how long it has expired and the storage conditions to which it has been exposed. Rubbing alcohol is commonly used for cleaning and disinfecting, so its effectiveness can diminish over time. Here’s what can happen if you use expired rubbing alcohol:

Expired Rubbing Alcohol may Reduce the Effectiveness

One of the primary concerns with expired rubbing alcohol is that its disinfectant properties may deteriorate over time. This means it may not be as effective in killing bacteria, viruses, and other pathogens, which defeats the purpose of using it for disinfection.

Expired Rubbing Alcohol may Weakened Alcohol Content

Rubbing alcohol typically contains either isopropyl alcohol or ethanol as its active ingredient. Over time, these alcohols can evaporate, reducing the alcohol content of the solution. A lower alcohol concentration can reduce its ability to kill germs effectively.

Expired Rubbing Alcohol may Have Altered Chemical Composition

As rubbing alcohol ages, its chemical composition can change. This can lead to the formation of byproducts or impurities that may not be safe for use on the skin or surfaces. These byproducts can potentially cause skin irritation or other adverse reactions.

Expired Rubbing Alcohol may be Potential for Contamination

An expired rubbing alcohol bottle may have been opened and closed multiple times, increasing the risk of environmental contamination. Contaminants like dust, dirt, or microorganisms can compromise its safety and effectiveness.

Expired Rubbing Alcohol Has the Ineffectiveness of Homemade Sanitizers

If you plan to use expired rubbing alcohol in DIY hand sanitisers or cleaning solutions, its reduced alcohol content and potential chemical changes could make your homemade products less effective in killing germs.

What Happens if you Drink Expired Alcohol?

Consuming expired alcohol, whether liquor, wine, or beer, is generally not harmful in acute poisoning. Unlike many perishable foods, alcohol does not typically spoil or become toxic as it ages. However, there are several factors to consider:

Taste and Quality

The taste and quality of expired alcohol may degrade over time. It can develop off-flavors, lose its aroma, or turn sour, making drinking less enjoyable.

Weakened Potency

Over extended periods, the alcohol content in a beverage can diminish slightly due to evaporation or chemical reactions. It may be slightly less potent than initially bottled, but the difference is usually negligible.


In the case of wine, certain types can age and improve with time, but this depends on the wine variety and storage conditions. On the other hand, most wines are not meant for long-term ageing and can deteriorate if stored improperly.

Safety Concerns

While the alcohol doesn’t become toxic, the packaging, such as corks and seals, may degrade over time, allowing air to enter the bottle. This can lead to oxidation and spoilage, resulting in a wine or liquor that is no longer pleasant to drink.

Final Words

Drinking expired alcohol can have a range of potential consequences, including changes in taste and quality, weakened intoxication effects, the risk of gastrointestinal discomfort, and the potential for harmful byproducts in some cases. The severity of these outcomes depends on factors such as the type of alcohol, the degree of expiration, and individual tolerance. To ensure a safe and enjoyable drinking experience, it’s advisable to consume alcohol within its recommended shelf life and to store it properly to prevent spoilage and deterioration. It’s also important to exercise caution and discretion when considering whether to consume alcohol that has passed its expiration date.
