    Be sure to use distilled white vinegar instead of something like apple cider vinegar. Once you’ve added the vinegar, fill your bottle to about the halfway point with warm water. [1]
    • White vinegar will sanitize your water bottle as well as get rid of any odors.
    • Another option is to use ¼ cup (59 ml) of hydrogen peroxide and not add any water. [2]
    • Use some of the white vinegar solution to clean around the outside of your bottle. For example, if you have a bottle with a twist-off lid, dip a paper towel or napkin into the solution and use it to sanitize the rim of the bottle where you usually put your mouth.

    Keep shaking your bottle for about 30 seconds to make sure that the entire interior surface is coated with the vinegar-water solution. Then, leave the bottle to sit overnight so that the vinegar has an ample amount of time to sanitize it. [3]

  3. Dump out the vinegar-water solution and rinse out your bottle once last time with clean, warm water. Then, use a clean kitchen towel or paper towel to completely dry out the inside. Or, let your bottle sit out with the lid off to air dry.
    • If there are still some stubborn spots, go in with a bottle brush or something like a toothbrush to scrub at those spots.
    • Use some of the vinegar solution to also clean the bottle’s lid, mouthpiece, or any other accessories that come with it, such as a reusable straw. Use a straw brush or a pipe cleaner to clean out reusable straws and rubber mouthpieces.

    Add 3-5 drops of dish soap to the bottle, then screw the lid back on. Any mild dish soap, preferably without added scents, will work for cleaning your plastic bottle. [7]
    • Clean your bottle with soap and water at the end of each day, especially if you bring it to a place that might have a lot of germs, such as the gym, your office, or school.
    • Avoid leaving water and other beverages in your bottle for a long period of time and dump out liquids whenever you’re not using your bottle.
  2. Watermark wikiHow to Clean a Plastic Bottle
    For a speedy clean, shake the soapy water around in your bottle with the cap on for about 30 seconds. Then, dump the soapy water out and rinse your bottle with clean, warm water.
  3. Watermark wikiHow to Clean a Plastic Bottle
    Scrub any stubborn buildup with a sponge or bottle brush . Use a bottle brush to reach deep into the bottle, paying extra attention to the bottom and the rim near the opening. Squeeze a bit more dish soap on your brush if the spots are particularly tricky to scrub away. When you’re done, rinse the bottle one more time with clean water. [8]
    • If you don’t have a brush, use a sponge to clean near the top of the inside of the bottle or a clean toothbrush (that you don’t use to brush your teeth) to get spots closer to the bottom.
    • Use a straw brush or pipe cleaner to clean out the small crevices in your bottle’s lid and in the insides of any reusable straws or plastic or rubber mouthpieces you have.
  4. It’s recommended to wash your bottle in the evening so you can leave it out overnight to air dry. If you can’t do this, dry your bottle completely with a clean dish towel or paper towel before using it.
    • Leave the lid off of your water bottle when you let it air dry. Screwing the cap on while there’s still water inside can cause bacteria to grow.

  1. Most products today are safe in the dishwasher, but check your bottle just to be sure. Take the top parts off of the bottle and be sure those go into the dishwasher too. The symbol usually looks like a small picture of a dishwasher, or illustrations of dishes or cutlery. [9]
    • If your bottle also comes with a reusable straw, make sure that it’s also dishwasher-safe.
    • If you’re unsure about whether your bottle and its accessories can be put in the dishwasher, check the site of the manufacturer your bottle came from.
  2. Watermark wikiHow to Clean a Plastic Bottle
    Unscrew the lid from your bottle and remove any other accessories, such as a reusable straw. Then, place the separate pieces onto the top rack. Many dishwashers have a heating element in the bottom for the dryer setting that can warp or melt plastic if it’s on the bottom rack. [10]
  3. Watermark wikiHow to Clean a Plastic Bottle
    Add your detergent and run your dishwasher with the plastic bottle on the top rack just like you would regularly run a load of dishes. Leave the dryer setting on so that the bottle gets completely dried. [11]
    • Or, take the water bottle out as soon as it’s done being washed and dry it thoroughly with a kitchen towel or paper towel.

    You only need a little bit of bleach to give your water bottle a deep clean and sanitize it thoroughly. Pour this mixture into your water bottle, place the lid back on, and gently swirl the water bottle around to make sure the entire inside is covered in the solution.
  2. Watermark wikiHow to Clean a Plastic Bottle

    • If you don’t have a bottle brush or straw brush, items like an old toothbrush, sponge, or pipe cleaner will work just as well.

Rinse everything 2 or 3 times to really make sure you’ve gotten rid of all of the bleach, then dry everything with a dish towel or paper towel. [13]
