How to Sanitize Jars


Canning is a traditional method of preserving food that is growing again in popularity. An increasing number of people are growing food in their own gardens, for economical and ecological reasons, and they can the produce for storing during the winter months. An important step of the food canning process is to sanitize the jars. If this step is not taken, you run the risk of your food spoiling in the jar well before its time.

Boiling Water Mehod

Step 1

Pour water into a pot of water--enough water to go above the level of the jars. Set the pot on the stove and bring the water to a boil.

Step 2

Set the jars in the rack and lower it into the pot of water.

Step 3

Keep the jars in the boiling water for 10 minutes. Lift the rack and the jars from the water and start canning your food.

Dishwater Method

Step 1

Set your canning jars in your dishwasher.

Step 2

Allow the cycle to run. Use your regular detergent as you run the dishwasher.

Step 3

Take the jars from the dishwasher and use them to can your food. The temperature of the water in the dishwasher reaches 120 degrees Fahrenheit, which is more than enough to sanitize your jars.
