The best way to dispose of unwanted rubbing alcohol is by taking it to an approved disposal facility. The fumes from rubbing alcohol are dangerous to breathe in and can cause serious damage to your lungs.
You could use sand or litter to absorb the liquid and then dispose of it. If you are really that freaked out about it, you can take it to a hazardous waste facility.
Pour it down the drain: If it's a small amount of drinkable alcohol, it can be diluted with water and poured down the sink. Make sure to run the water while you pour to dilute it effectively. Check with local waste facilities: Some areas have specific guidelines or facilities for disposing of alcohol.
It'll be good for roughly 3 years, you can just keep using it for cleaning/disinfecting things within that time, and dilute it with water and mix with soap for a pretty good grease fighting spray. It's also safe to dilute down to 5% with water and just drop it down the sink.
Under ideal storage conditions, the shelf life of IPA is roughly three years from the manufacture date.
The main difference between isopropyl alcohol and rubbing alcohol is the concentration. The concentration of isopropyl alcohol is 100%, while the concentration of rubbing alcohol is less because of the addition of water. Otherwise, the two liquids have similar properties.
How to dispose of spoiled drinking alcohol. Just like rubbing alcohol, it is generally acceptable to dispose of small amounts (not more than 2-3 bottles) of water-diluted drinking alcohol down the drain.
Trying to revive your old, or expired, hand sanitizer by adding rubbing alcohol to it (something many people attempt) isn't a good idea. So says the CDC, who explains that's unlikely to produce an effective hand sanitizer product.
Isopropyl alcohol (IPA) is not a RCRA listed hazardous waste solvent; however, it may exhibit the hazardous waste characteristic of ignitability. This particular characteristic applies to the IPA as a liquid.
It's OK to keep using expired hand sanitizer, as long as it still evaporates quickly and smells strongly of alcohol. It is still effective. If hand sanitizer is NOT effective anymore, contact your Building Manager or Division Safety Coordinator. Keep hand sanitizer out of the trash and do not pour it down the drain.
Neutralization is effected by treatment with an alkaline earth metal hydroxide or with an alkali metal hydroxide. Sodium hydroxide is the preferred agent for effecting neutralization.
If your local government doesn't specify how to dispose of rubbing alcohol, be on the safe side and bring the sealed container to a household hazardous waste site.

"Let it sit for about 10 seconds and gently rub it back and forth.
According to the World Health Organization, all alcohol-based products are potentially flammable and therefore they should be stored away from high temperatures and flames.
Final answer: Expired isopropyl alcohol is less effective for sanitizing because alcohol content declines over time due to evaporation. While not suitable for sterilization, it may still be used for general cleaning.
Find a well ventilated room with a sink and pour it slowly while running lots of water to dilute it. The general guideline is that about 5% or less IPA can be poured down the sink, so pour a small volume of IPA followed by a lot of water (and repeat until its gone) and it'll be fine.
Instead, EPA recommends that household hand sanitizer waste be brought to a household hazardous waste drop-off location or event for proper management. Household hazardous waste locations and events are frequently run by local government agencies.
All types of alcohol (and other wastes) are able to be recycled, from pure ethanol, methanol or Isopropyl to any complicated combinations. If you're a producer of alcohol waste or use alcohols in any types of manufacturing then you're a perfect fit for a recycling option.
People should avoid inhaling large quantities of rubbing alcohol vapor, as this can have serious side effects. They should also avoid long-term use of rubbing alcohol on the skin. Drinking rubbing alcohol can cause poisoning and serious illness.
Hydrogen peroxide is another antiseptic, or disinfectant, that kills viruses and various forms of bacteria. But it needs more time than rubbing alcohol to kill germs. It takes up to five minutes to do its job. Hydrogen peroxide also can kill the virus causing COVID.
