- Hot soapy water works wonders to sanitise water bottles and glass bottles.
- Do not overuse dishwashing liquid as this could make it hard to remove all the bubbles!
- You can buy specialised sanitising tablets to ensure your bottles are extra hygienic.
We all know how convenient simply refilling a used water bottle can be – and how important it is to save resources by reusing or recycling glass bottles wherever possible. But how do you clean them first, to make sure they’re safely sanitised? This guide talks you through cleaning glass bottles and explains how to clean out a water bottle so that you can reuse bottles safely and hygienically.
Has your cleaning regime changed during the Covid-19 lockdown?
How to Clean a Water Bottle
Possibly the easiest method for cleaning a water bottle is to simply stick it in the dishwasher. However, cleaning water bottles by hand on a daily basis with dishwashing soap and hot water is just as easy and effective – if not more thorough!Follow these simple steps to make sure you have clean and hygienic water bottles:
1) How to clean water bottles:
- Fill the bottle with very hot water.
- Seal, shake and discard around half the water.
- Add a pea-sized amount of dishwasher soap, seal, and shake again to create lather.
- Squeeze or pour as much liquid as possible out through the nozzle or opening on the cap (if there is one) – this will help to clean the cap too.
- Rinse thoroughly.
- Leave to dry on the draining rack.
- Rinse again before putting away or reusing.
2) How to deep clean water bottles
- Dilute 1 teaspoon of bleach and 1 teaspoon of baking soda in 4 litres of water.
- Fill the bottle with the solution and leave overnight.
- Squeeze or pour the solution out through nozzle or opening.
- Rinse very thoroughly, ensuring that all the cleaning solution is removed.
- Leave to dry on a drying rack as before.
- Rinse again before reusing.
Remember: follow the safety guidelines on the label when using bleach and be sure it has thoroughly been rinsed out of any bottle before drinking from them again.
How to Clean a Glass Bottle
To a certain extent, the techniques needed to clean glass bottles depend on what they’ve been filled with previously. Oil, alcohol, syrup and milk all leave slightly different residues behind.
Again, simply putting glass bottles or jars through the dishwasher is a cheap and low-effort method of sanitising them, but if this is not readily available to you, there are other ways of cleaning glass bottles inside and out that are equally effective.
- Wash with hot water and dishwasher soap as with water bottles.
- Use a weak bleach solution, as with water bottles, but without the baking soda.
- Use specifically designed sanitising tablets. Drop one into a bottle full of warm water and leave for 15-30 minutes, then rinse and enjoy. Read and follow the product instructions to get the best results.
- Use a specially designed, no-rinse, sanitising solution in a bottle already cleaned with another method. Once again, read and follow the product instructions.
Cleaning glass bottles and water bottles is a safe and environmentally friendly way of obtaining sealable containers for future use. Just be sure to store them safely, and label them clearly if necessary – there’s nothing worse than getting your shampoo mixed up with your salad dressing!
