There is some natural apprehension around ammonia. It's a highly corrosive cleaner with a strong smell that creates seriously toxic fumes if mixed with the wrong chemicals. However, disposal is simple and can be done safely as long as you take the proper precautions. Use this guide to learn how to dispose of ammonia and ensure you get it right.

Prepping to Dispose of Ammonia 

Ammonia is an extremely corrosive chemical harmful to humans and animals, per the EPA. Contact with bare skin can cause irritation or chemical burns. Prolonged exposure to ammonia fumes can irritate the eyes, nose, and throat and cause breathing problems, headaches, and dizziness. If it leaks into soil or water supplies, ammonia can kill plants and fish and lead to harmful algae growth.

If you have other chemicals to dispose of in addition to ammonia, get rid of the ammonia separately first and rinse all plumbing and containers thoroughly before disposing of the others. Mixing ammonia with other chemicals, especially bleach, can produce poisonous gas. When it comes to how to dispose of bleach properly, ammonia should not be anywhere nearby.

Other precautionary measures to take while disposing of ammonia include:

  • Wearing protective gloves, eye goggles, and a face mask to cover your mouth and nose

  • Clearly labeling containers containing ammonia, especially if storing them before disposal

  • Thoroughly ventilating the area by opening windows and doors and running a fan

  1. Dilute the Ammonia and Dispose of Liquid Material

    Wearing safety gear in a well-ventilated space, begin by diluting the ammonia with water to reduce its potency. The easiest way to do this is to turn on the tap in your sink and slowly pour the ammonia in as it runs. Alternatively, you can flush small amounts of ammonia down the toilet, though this will take longer.

    Ensure that you do this slowly enough that there is more water than ammonia going down the drain or toilet at once. Otherwise, you run the risk of contaminating your groundwater supply or damaging your plumbing. If you have a septic system, you can avoid this risk entirely by skipping this step.

  2. Neutralize Ammonia and Dispose of Solid Material

    It’s important to know how to neutralize ammonia before handling it. If you have spilled any ammonia, or you wish to avoid pouring or flushing it directly down the drain, you can use an absorbent mixture of cat litter, baking soda, dry sand, and sawdust to neutralize it.

    Combine any or all of these components in a large container to create your mixture. You can then spread the mixture onto any spills or slowly pour liquid ammonia into the mixture, taking care not to oversaturate it. Once the ammonia has been absorbed, sweep up the solid waste and dispose of it in the trash.

  3. Rinse Empty Containers

    Ammonia containers can still contain traces of ammonia and produce harmful fumes. Before tossing or recycling empty ammonia containers, thoroughly rinse them with water to remove these trace amounts. Thoroughly rinse the sink afterward as well.

DIY vs. Hire a Pro to Dispose of Ammonia

For the most part, you’d be hard-pressed to find a plumber, cleaner, or other professionals to come by and dispose of your ammonia for you. However, you can hire a local junk removal company to take just about anything off your hands. If you’re only getting rid of a little bit of leftover ammonia, it’s probably not worth the cost of junk removal, though.

Frequently Asked Questions

No, you cannot throw away a bottle of ammonia or ammonia-based cleaner in your regular garbage. Instead, dilute it and pour it down the drain or dispose of it in the trash as a neutralized solid material. You can also contact local chemical companies to see if they’ll accept unused containers of ammonia since it does not expire.

Yes, ammonia does damage pipes if used or disposed of improperly. Although ammonia-based cleaners are commonly used to unclog drain pipes, they either come already diluted or instruct the user to dilute them before use. Otherwise, undiluted ammonia is too caustic and could corrode certain plumbing types, such as PVC.

Ammonia can dissipate in minutes, hours, or even weeks. It depends on how heavily concentrated it is and the size of the space it’s exposed to. Always err on the side of caution when dealing with ammonia. Call your local poison control center or police department if you’re unsure what to do.
