Keeping plastic bottles clean not only prolongs their life but also helps prevent health problems.
Plastic bottles have become an indispensable part of everyday life thanks to their practicality and low cost. They are easy to clean, easy to recycle and help reduce the use of disposable packaging. However, if they are not properly disinfected, they can accumulate bacteria and develop an unpleasant mouldy smell.
The best cleaning tricks to keep metal surfaces looking like new
One of the most common mistakes is forgetting to wash the bottle regularly. Many people just fill it up without paying attention to its cleanliness, which can lead to the growth of microorganisms. Stagnant water and residual liquids encourage the growth of mould and bacteria, increasing the risk of contamination. To avoid this, the bottle must be kept clean and dry at all times.
How to clean a plastic bottle step by step
To remove odours and accumulated residues , first rinse the bottle with warm water and detergent.It is recommended to fill the bottle with this mixture and shake it to ensure that the soap reaches all the internal surfaces. It should then be left to stand with the lid on for 15 to 30 minutes to enhance the cleaning effect.
After resting, the bottle should be rinsed several times with clean water to ensure that no soap residue remains. The bottle must be dried completely before re-use, as residual moisture may cause unpleasant odours.

If there is time, leaving the bottle in the sun for a few hours is a natural and effective way to remove bacteria and odours. Ultraviolet rays act as a disinfectant and leave the bottle smelling fresh. This action is particularly useful for bottles that have been closed for a long time with liquids inside.
To prevent the problem from recurring, it is advisable to dry the bottle after each use and store it in a cool, dry place. Liquids should not be left inside for too long as this creates a breeding ground for micro-organisms. In addition, regular re-cleaning of the bottle ensures that it remains in optimal condition.
The vinegar method for removing persistent odours
If the bottle still smells mouldy after washing, you can use white vinegar, a natural deodorant with antibacterial properties. To use it, fill the bottle with equal parts whitevinegar and water and leave it for at least 15 minutes. Then rinse with plenty of clean water to remove any vinegar residue and allow to dry completely.
This method is particularly useful for bottles that have developed a strong odour or have not been cleaned for a long time . If the problem persists, you can repeat the process or add a small amount of baking soda to the mixture to enhance the deodorising effect.
