How To Sterilize Glass Jars And Bottles

I do not go in for the whole rigmarole of the canning process where you boil bottles and then dry them in the oven. I have been using this method to sterilize glass jars and bottles with great success for over 20 years, and I reckon it works!

  • wash your jars / bottles in warm soapy water and rinse
  • fill your clean glass jars / bottles with boiling water and leave to stand for one minute
  • empty and place the glass jars / bottles into your microwave
  • heat on full power until dry – this should take about 2 minutes
  • put the lids into boiling water and use straight from there to seal your jars / bottles

I have followed other methods for sterilizing and if you have the necessary equipment then boiling the jars in water in a stock pot on the stove beforehand also works well. But it is laborious as you have to dry them in a preheated oven. This is also such a huge waste of energy in my opinion. You can also wash the jars using the hottest setting in your dishwasher. If you are lucky like I am and your dishwasher has a special feature where you can just clean the items on the top shelf then it works a treat. Some dishwashers also have baby bottle sterilization options as mine does, but I have never used this. But, if cannot make use of the top shelf only in your dishwasher, you would be wasting a whole lot of water and electricity for only a few jars or bottles. Another alternative is to top your jars with boiling water, leave to stand for a minute and then tip the water out. You then leave the jars to air dry. But this takes a lot more time than using my method of drying the bottles in your microwave. And the microwave method takes less than 5 minutes from when your water has boiled to when the jars are dry and ready for use. I do not like to waste water and so I pour the water into a jug and use when cool to top up our dogs’ water bowls.
