Choose an Appropriate Method

Isopropyl alcohol is a common household cleaner and disinfectant that is used to clean surfaces, kill germs, and remove adhesives. While it is generally safe to use, it is important to dispose of it properly to avoid any potential hazards.

Evaporation

Evaporation is the simplest and most common method of disposing of small amounts of isopropyl alcohol (less than 1 liter). Simply pour the alcohol into a shallow container and set it in a well-ventilated area. The alcohol will evaporate into the air, leaving behind any contaminants. This method is suitable for small quantities of alcohol that are not contaminated with hazardous substances.

Dilution and Sewer Disposal

Dilution and sewer disposal is a suitable method for disposing of larger amounts of isopropyl alcohol (up to 5 liters). Dilute the alcohol with a large volume of water (at least 10:1 ratio) and then pour it down the sink. Flush the drain thoroughly with water after disposal. This method is only suitable for alcohol that is not contaminated with hazardous substances.

Method	Suitable for	Limitations
Evaporation	Small amounts (less than 1 liter)	Not suitable for contaminated alcohol
Dilution and Sewer Disposal	Larger amounts (up to 5 liters)	Not suitable for contaminated alcohol

Dilute and Pour Down the Drain

Step-by-Step Instructions:

Assess the volume of isopropyl alcohol to be disposed of. If it’s less than half a gallon, you can proceed with dilution.
Prepare a large bucket or container with cold water. The amount of water needed will depend on the volume of alcohol. As a general guide, use twice the amount of water as alcohol. For example, for 1 cup of alcohol, use 2 cups of water.
Carefully pour the isopropyl alcohol into the water. Do not add the alcohol to hot water, as this can create flammable vapors.
Stir the mixture thoroughly to ensure complete dilution. The diluted solution should be a clear or slightly milky liquid.
Pour the diluted solution down the drain slowly. Do not flush large quantities at once, as this can overload the drain or treatment system.
Rinse the drain thoroughly with water after pouring to prevent residue buildup.

Precautions:

Never pour undiluted isopropyl alcohol down the drain. It is flammable and can pose a safety hazard.
Check with your local water treatment plant or city guidelines to confirm if diluting and pouring isopropyl alcohol down the drain is allowed in your area.
If you are unsure or dealing with large quantities of isopropyl alcohol, contact a licensed waste disposal company for proper handling and disposal.

Dispose of at a Waste Disposal Facility
