5 Significant Ways For Removing Odors From Plastic Water Bottles:

In short, I have collected 5 best methods you can use one by one to ensure that your reusable plastic water bottle never smells bad. Please have a look at those methods. These are as follows.

Method 1: Using Soap And Water Bottle Brush To Clean A Plastic Water Bottle: 

The classical cleaning method is the first thing or solution to remove the smell from a plastic water bottle.

This includes using soap and water to clean a water bottle properly. Please follow the steps below to learn how to clean a smelly plastic water bottle with soap?

  • At first, open the lid of your plastic or any reusable water bottle you carry.
  • Enter some water into it. Then take a bowl and mix soap with water into it. When you have a solution, could you insert it into the water bottle?
  • Close the bottle with its cap and shake it with more force.
  • Once done, use a water bottle cleaning brush to clean every inch of the water bottle from the inner side. However, this brush type is only required when your water bottle has a narrow opening.
  • Now, clean the water bottle with clean water and let it dry for a while.
  • Take it closer to your nose and smell it to find out whether it is fresh or still stinking bad. Go for the next step if there is still odor coming from it.

Method 2: Dishwasher Washing Of Water Bottle:

In case you have a heavy-duty built plastic water bottle or a stainless steel water bottle which is dishwasher safe, cleaning would be a lot easier than you can imagine. For this, do the following things.

  • Open the lid of your water bottle and try putting that water bottle into the dishwasher.
  • Go for a full “hot” cycle. When that water bottle passes through high temperatures and stronger dishwasher detergents, it will be cleaned out fully.
  • However, go for the next step if it is still that same funky water bottle.

Pro Tip: Please don’t consider putting a plastic water bottle in a dishwasher for a hot cycle. Because most plastic water bottles start melting under high temperatures.

Method 3: Try Using Hot Boiling Water:

Most probably, if that plastic water bottle is made from plastic materials such as PET, HDPE, or PP, it will not be affected by hot temperatures.

In that case, you can even use hot water to remove bad smells from that water bottle. Follow the steps below to perform something like that.

  • Suppose that the dishwasher method was not quite useful. If you don’t have a dishwasher at home, trying this hot water method is all worth it. It is usually recommended for stainless steel water bottles.
  • Please take some hot water or boil it in a cattle. Now open the lid of that water bottle and pour this hot water into it.
  • Once this is done, let the water bottle sit overnight.
  • Now, you can use soap to wash it properly so that you may attain the original smell of your water bottle instead of that bad one.

Method 4: Use Detergent Or Washing Liquid To Remove Odors From A Plastic Water Bottle:

This method is somewhat similar to soap cleaning a smelly water bottle. Therefore, follow the steps below to learn this method completely.

  • At first, take detergent or that washing liquid and mix it with the water as you do for cleaning dishes. Or sometimes clothes.
  • Take this solution in a bowl and use any sponge as well. Pour a little quantity of this solution into the water bottle. Close the lid and shake the water bottle forcefully.
  • After that, use clean water and remove that liquid from the water bottle. Consider using a brush as well if your hand cannot reach inside the water bottle for a definite cleaning.
  • When this is done, soak out the extra water and let the water bottle dry for a while.
  • You will see that the smells have been completely removed from that water bottle. But if not, there is still something that you can do!
