Nonetheless, there are several guidelines you should adhere to before placing the Mason jar in a dishwasher.

After the detergent is in place, switch on the dishwasher and ensure that the settings are appropriate. Leave the jars to clean for some time.

Step 4: Clean The Mason Jar Lids

After cleaning the jars, you can clean the lids in the dishwasher. Just put the lids in small compartments or dishwasher holders. Add some detergent and allow the lids to clean.

1. Do You Need To Wash New Mason Jars Before Use

A short and precise answer to this question is yes! We know you are wondering why you should wash new mason jars, yet you will subject them to high temperatures during canning.  

However, you need to realize that cleaning the mason jars is a vital step in food preservation.  Cleaning your jars is essential to remove any bacteria or yeast that will contaminate the canned food.

If the food is contaminated, it is likely to go bad at a faster rate than usual. Furthermore, you can acquire diseases after eating in contaminated mason jars!    

It doesn’t matter if the mason jars are new. A clean wrap doesn’t guarantee a clean environment.

Clean mason jars can be contaminated by chips, debris, dust, and microorganisms during manufacturing or packaging.

Washing the mason jars is obligatory before you start the canning process. In fact, national food preservation agencies insist that at the very minimum, mason jars should be washed in hot water with a detergent.

As you wash the jars, inspect them thoroughly for existing cracks. Also, remove any existing films by soaking them in a vinegar solution.

After washing the jars, make sure you rinse them thoroughly to prevent the detergent from damaging food.

2. Cleaning In Boiling Water

Put the mason jar in boiling water and leave it for some minutes.  Then, turn off the heat source as soon as steam starts emerging from the pot.

Leave the mason jars in hot water for 5 minutes so that they can remain hot. After 5 minutes, flip the jars on a towel and allow them to dry.

However, ensure that the jars remain hot. It is recommended that you only use the Mason jar when it is still hot.

3. Cleaning The Mason Jar In A Dishwasher

This is the most efficient method.

Start by putting the mason jar in the dishwasher. Then rinse the jars at a high-temperature setting. It is also vital to lock the dishwasher to ensure that all the heat is locked inside.

Pull the jars outside slowly, one at a time, so that they remain hot while packing the food.

4. The Oven Method

Though this is the easiest method, it consumes a lot of time.

To clean the Mason jar, heat the oven to 280 degrees F. Next, put the jars inside the oven for a period of twenty minutes.

However, ensure that you place the jars on a cookie sheet to prevent them from breaking due to increased heat. 

Don’t heat the oven above 280 degrees F. The mason jars will crack if you surpass the recommended temperatures.

Once twenty minutes are over, remove the jars with a heatproof mat. Fill in the food contents while the Mason jar is still hot.

You are free to select any cleaning method from the three options. However, you need to remember that cleaning new mason jars is a requirement!

Now, we know you are wondering if it is possible to detach the wire bail mechanism. Well, the good news is it is possible.

However, this is only possible in a limited number of glass jars. Once you detach the wire bail mechanisms, your mason jar will be dishwasher safe.

To effectively clean your mason jars, put them in the dishwasher. Then run the dishwasher on a minimum time setting. Afterward, rinse the jars in a high-temperature setting.

Within few minutes, your mason jars will be sparkling clean. You can now pull them out of the dishwasher.

Important Note: For this cleaning to be done correctly, you must ensure that the mason jars are the only utensils in the dishwasher. The dishwasher should not contain other dirty dishes. Also, note that this cleaning method is expensive. It consumes an exceptional amount of energy and water.
