Cloudy buildup inside old bottles doesn’t scrub itself out, and narrow necks make the job even more annoying. This simple overnight bottle-cleaning method tackles residue with warm water and a small amount of ammonia, so you can clean collectible bottles without wrestling a brush into impossible corners (because apparently bottles enjoy a challenge).
Fill the bottle warm water, then add ammonia, keeping away from pets/kids/etc
Making a small batch yourself costs very little compared to buying a specialty bottle-cleaning product. Based on a current Walmart price of about $2.12 for a 64-ounce bottle of clear ammonia, 1 to 2 teaspoons works out to just a few cents per cleaning, and you control the strength by using either 1 teaspoon or 2 teaspoons depending on what the bottle needs.
You only need 2 materials for this method: warm water and 1 or 2 teaspoons ammonia. The original directions make one cleaning batch directly in the bottle you’re washing, so the actual yield depends on the size of your bottle. Keep a measuring spoon handy, and use your usual washing and rinsing setup the next day.

How to Use It
Use this cleaner when you need an easy soak for collectible bottles with light interior residue or dingy film. If you clean insulated drinkware instead, try this Thermos Bottle Cleaner, and if you need more ideas for narrow glass containers, see How to Clean Vases & Bottles Easily.
Safety Information
Keep ammonia away from children and pets, and do not use this method for baby bottles. Open a window or work in a well-ventilated area, and never mix ammonia with bleach or other cleaners. The CDC specifically warns that mixing household cleaners can release dangerous vapors, including when ammonia is combined with bleach. See their guidance here: Ammonia Chemical Fact Sheet.
Storage
Use the soaking mixture right away in the bottle you’re cleaning, then wash and rinse the bottle as usual after the overnight soak. Don’t store leftover mixed solution in a drink container or reuse it for baby bottles.
Estimated Cost
Estimated cost per use: about $0.03 to $0.07, depending on whether you use 1 or 2 teaspoons of ammonia and the current store price. That estimate covers the ammonia only. Water and routine washing supplies will vary by household.
