DIY Solutions: How Do You Clean Bottles Using Household Ingredients?

Water bottles are ideal to deliver hydration on the go, but they can easily attract bacteria if not cleaned regularly and properly. Whether you have a stainless steel or glass bottle, keeping it clean is crucial for your health. So, if you are curious about how to clean water bottles, follow the methods as mentioned below. 


Everyday Wash Routine 

A simple yet effective way to keep your water bottle clean is to develop a strict routine to wash and rinse your bottle every day. From glass to copper bottles, this method is suitable for all types of materials. 

Method: 

  • Once your beverage is finished, wash your bottle thoroughly with hot water to remove residual liquids and prevent foul smell. 

  • Want to know how to clean the bottle inside? Take a bottle brush and mild dish soap to scrub the interior part of the bottle. Wash it with hot water to remove all the traces of soap.

  • Keep the bottle upside down and allow it to air dry to prevent the chances of bacterial growth. 


Deep Cleaning with Vinegar and Baking Soda

If you are looking for a deep cleaning method to eliminate tough stains and foul smells, try Baking soda and vinegar for effective results. 

Method: 

  • With Baking Soda: Sprinkle 2 tablespoons of baking soda in the bottle and fill it half with warm water. Close the lid of the bottle and shake it thoroughly to form a scrubbing solution. Use a bottle brush to remove the stains. 

  • With Vinegar: Pour 2 tablespoons of vinegar into the bottle and fill it halfway with water. Allow the vinegar solution to rest in the bottle for a few minutes, allowing it to disinfect the bottle and remove foul smells. 

  • Rinse the bottle thoroughly with hot water and air dry it before storing or using it again to prevent bacterial growth. 


Sterilise in Boiling Water

Wondering how to clean glass bottles? Well, sterilising them in boiling water can effectively kill bacteria and remove tough stains and residues. 

Method: 

  • Boil an adequate amount of water based on the quantity of your bottle.  If the water is too hot, allow it to cool for a few seconds to avoid thermal shock to the glass. 
  • Carefully pour the water into the bottle and close the lid. Thoroughly shake the bottle to ensure that the water reaches all the surfaces for effective cleaning. 
  • Drain the hot water and allow the bottle to air dry completely before storing or using it again. 


Bleach Solution

If you are looking for effective ways to clean a stainless steel water bottle, use a mixture of bleach and water to remove stains from the bottle and maintain its texture. 

Method: 

  • Take 1 teaspoon of bleach and mix it with 1 L of water. It is recommended to use unscented bleach that is suitable for disinfecting steel utensils. 
  • Dip the water bottle into the solution for 5 minutes. Use a bottle brush to clean the interior of the bottle gently.
  • Wash the bottle thoroughly with warm water to remove any residue of bleach and allow it to air dry. 

Note: If you have coloured steel or personalised bottles, then avoid using this method, as it can damage their appearance. 

How Often Should You Clean Your Water Bottle?

Daily Cleaning

For daily-use bottles, rinse and clean them every night to prevent bacteria buildup and odours.

Weekly Deep Cleaning

Bottles used for juices or smoothies should be deep-cleaned weekly to remove any residue and prevent lingering smells.

After Each Use

For bottles holding coffee, tea, or sports drinks, clean them after each use to avoid stains and odours.

 

Daily Maintenance: Tips for Long-Lasting Use

Avoid using dish cloth or sponges as they do not reach the bottom or the sides of the bottle effectively. Instead, use a bottle brush for thorough cleaning. 

Lids, caps, and straws are the hotspots for attracting germs, and they should not be neglected. It is recommended to soak these components in soapy water or warm water to remove bacteria. 

Ensure that your water bottle is sanitised once a week for healthy hydration. 
Moisture on the bottle can lead to bacteria; therefore, it is essential to thoroughly dry your water bottle before storing it. 

Do not leave liquids in your water bottle for extended periods, as it can lead to bacterial growth, unpleasant smells, and tough stains. 


Bottom Line

Understanding how to clean a steel water bottle or glass water bottle is crucial for maintaining hygiene and ensuring safe hydration. Regularly washing with soap and water, using a bottle brush for hard-to-reach areas, and occasionally using vinegar or baking soda for deep cleaning can keep your bottles free from bacteria and odours. Adequate maintenance extends the life of your bottles and promotes hygiene.
