12 Useful Things You Didn’t Know Your Freezer Could Do

Uses For Your Freezer

Today’s post is an ode to the freezer, the fridge’s under-appreciated sibling. I use my freezer to store all kinds of things—frozen foods, leftovers, freezer meals, fresh fruits and veggies, and more. I even wrote a post about what kinds of foods you can freeze to save yourself time and money, which you can check out at the link below.

But we won’t be talking about food today. Instead, we’ll be exploring useful ways you can use your freezer that have nothing to do with food. By the end of this post, you’re sure to have a whole new appreciation for just how useful your freezer can be.

12 Unexpected Ways To Use Your Freezer

Uses For Your Freezer

1. Open A Sealed Envelope

Have you ever sealed an envelope and then realized that you left out something crucial? How annoying! Luckily, your freezer can help you fix it.

Just place the sealed envelope in a ziplock bag and freeze it for 1 to 2 hours, then take it out and immediately open it back up with a blunt knife or a letter opener. Let the envelope return to room temperature, then remoisten the adhesive to seal the envelope again.

2. Make Candles Last Longer

Place new candles in your freezer for a day before lighting them. Chilled wax burns slower and thus makes the candles last longer (and with some candles, it can even prevent the wax from dripping.)

3. Refresh Your Jeans

If the threat of fading or shrinking has you nervous about washing your nice denim jeans, roll them up and stick them in a canvas bag, then place the bag in your freezer overnight. The frigid temperature in the freezer will kill any odor-causing bacteria, which will freshen your jeans without affecting their color.

4. Freshen Smelly Shoes

The same principles above work just as well with smelly shoes too. Just seal a pair of smelly shoes into a ziplock bag and stick the bag in your freezer overnight to kill odor-causing bacteria.

5. Kill Bugs

Wooden antiques can sometimes harbor woodworm, which are the larvae of beetles. These little critters can chew right through your wooden antiques, leaving unsightly holes. If you bring home a new wooden item and you’re not sure about how bug-free it is, stick it in your freezer for a couple of weeks. The prolonged exposure to cold temperatures should kill any woodworm.

Other household items can be magnets for creepy-crawlies, including your bedding. Dust mites love bedding because it’s generally rife with dead skin cells for them to eat. You can take care of any dust mites by putting the item in question in your freezer overnight. Give it a wash in the morning, and it’ll be fresh, clean, and bug-free!

6. Simplify Plastic Wrap

Plastic wrap can be infuriating when it won’t stop sticking to itself, but you can use your freezer to simplify the process. Just stick the plastic wrap in your freezer for a few minutes to hamper the clinging action enough that it becomes easier to handle. (Don’t keep it in the freezer too long though, or it will lose its stickiness entirely.)

7. Save Seeds

If you have extra seeds that you want to use next planting season, you can keep them fresh in your freezer. Make sure they are completely dry first, then place them in an airtight container in your freezer. Then pull them out next spring, make your own seed tape (see the link below), and plant them.

8. Make Pantyhose Last

You can help extend the life of a new pair of pantyhose by freezing them. Get them wet, wring them out well, then stick them in a plastic bag and place it in your freezer overnight. Remove the bag in the morning and allow the pantyhose to thaw at room temperature. Let them air dry and they’ll be ready to wear.

9. Stretch Tight Shoes

Your freezer can help you stretch out that pair of shoes that’s just a bit too tight. The process involves freezing a bag of water inside each shoe, so that it gently stretches the shoe as the water freezes and expands. Get all the details at the link below.

10. Remove Gum

Using your freezer is one of the easiest ways to remove gum from the bottom of your shoe because it requires very little scraping. Just stick a sturdy piece of paper to the gum then place the shoe in your freezer for 1 to 2 hours. When you remove the shoe, the paper and the gum should peel away easily.

11. Prevent Sweater Shedding

I love a good fuzzy sweater, but I don’t love how much they tend to shed. But you can use your freezer to help prevent that dreaded shedding.

Roll up your fuzzy sweater or cardigan, place it in a ziplock bag, and stick it in the freezer overnight. The cold temperatures will make the fibers contract, which will keep them from shedding so much.

12. Makeup Hacks

Lipsticks will last a lot longer if you store them in your freezer. This is especially useful for preserving lipsticks that you only use on special occasions.

Your fridge or freezer is a great place to store your natural beauty products too, since they usually don’t have as many preservatives as standard beauty products. Put them in the fridge if you use them often, and the freezer if you use them sparingly.

And finally, your freezer can help give your eyeliner a super sharp point. Place your eyeliner in the freezer for 10-15 minutes before sharpening it, which will make the sharpening process easier. You’ll get a sharp, precise point!

Do you use your freezer for any unconventional purposes?

  • I used to work in service, and in hot weather, my feet would eventually swell a bit, and feel hot and sore. I was told to bring a second pair of shoes in a plastic bag, and place them in the freezer (or fridge) and change my shoes when my feet began to bother me. Slipping on the cold shoes was a wonderful feeling! My feet felt refreshed, and it helped the swelling. On long shifts, I might switch my shoes 2 or 3 times. AHhhhhh…….

  • Hi Gillian, I was just wondering if you could mute the video as it is interfering with reading the articles? The audio is “muffled” & those talking tend to over talk each other.

    I enjoy your tips & it is my “go to” website. Keep up the great work !!!

  • Ha! I’m ready to step in gum and remove it easily from the bottom of my shoe (for a change).

    Thank you so much, Jillee! Where were you when I was growing up?

  • I love using the freezer for getting rid of the tiny or (sometimes) not so tiny wax left in the bottom of a beautiful jar candle. These days so many of them come I’m such beautiful glass jars with lids that you hate to throw them out. If you stick the jar in the freezer for half an hour (sometimes longer depending how much wax is left in the bottom) when you remove from the freezer very carefully with a spoon or knife pop out the wax. It’s that simple. Wash out your jar, and you have a pretty jar for Knick knacks, craft supplies or marking another candle in.

  • Impermeable mattress covers and pillow covers pretty much solve the dust mite in the bed problem. They’re not cheap ($200 Canadian for a king size, but you can get them on sale), they completely enclose your mattress, and zip up. Just be sure you vacuum the heck out of your mattress first, or even use the hand-held upholstery steam cleaner attached to your upright carpet steam cleaner, OR, spray with hot water and a little laundry or handwashing detergent, suck the water out of the mattress with you shop vac, be sure to follow instructions for “wet pick-up”, and let the mattress dry completely. You can unzip and remove the impermeable cover any time, wash it (let it air dry, don’t put it in the dryer), vac the mattress while the cover is in the washer, and put the cover back on as soon as it’s dry. You will find your sheets stay fresher, longer (without all those toxic laundry additives which are supposed to “enhance” the artifical freshness), and that your mattresses will last much longer. Two people sleeping on a double or queen mattress, for ten years, without an impermeable cover, will increase the weight of the mattress by at least 20 lbs, due to dead skin cells sifting down thru the sheets, the standard mattress pad, and then through the mattress’ fabric. Yuk. :-)

    • Rosemarie B – Thanks for the awesome info on the mattress and pillow covers but I’m chuckling about ‘vacuuming your mattress while the cover is in the wash’. I though the whole idea for its use was to prevent anything from reaching or getting into your mattress. I though that if I used one and it actually works I would never have to vacuum my mattress again. LOL – from a fellow Canadian
