"Freezing" jeans is a method some people use to refresh them and eliminate unwanted odors without washing them. The idea behind this is that freezing temperatures can kill odor-causing bacteria. Here's how you can do it:

1. Check the care label: Make sure your jeans are suitable for freezing. Most jeans made of denim should be fine, but it's always good to double-check.

2. Empty pockets: Before freezing your jeans, ensure there is nothing in the pockets. This step helps prevent any potential damage to items or your jeans during freezing.

3. Fold the jeans: Fold your jeans neatly to ensure they fit properly in the freezer and to avoid excessive wrinkling.

4. Place in a sealable plastic bag: Put the folded jeans inside a large sealable plastic bag. A freezer-safe bag or a vacuum-sealed bag would work well to keep the jeans protected during the process.

5. Remove excess air: If you're using a regular plastic bag, gently squeeze out as much air as possible before sealing it. If you're using a vacuum-sealed bag, follow the manufacturer's instructions to remove the air.

6. Freeze the jeans: Lay the sealed bag flat in the freezer and make sure it's not pressed against other items to maintain its shape. Leave the jeans in the freezer for at least 24 hours to allow the freezing temperature to kill bacteria and remove any unwanted odors.

7. Thaw and air out: After 24 hours, remove the jeans from the freezer and let them thaw at room temperature. Once they are thawed, hang them outside or in a well-ventilated area to air out for a few hours. This step helps in getting rid of any remaining odors and ensuring the jeans return to their regular texture.

Please note that freezing your jeans is not a substitute for washing them. For proper cleaning and maintaining the longevity of your jeans, it's essential to follow the manufacturer's care instructions and wash them as recommended. Freezing can be a temporary solution for odor removal between washes but not a replacement for regular cleaning.
