Method 1: The Freezer Method (Super Easy!)

This is probably the easiest way to get wax out of candle jars — and it requires zero heat.

Here’s what you do:

1. Place your candle jar in the freezer for 2–4 hours (overnight works great too)
2. Take it out — the wax will have shrunk and pulled away from the sides
3. Use a butter knife or spoon to gently pop the wax out
4. It should come out in one or two clean chunks!
5. Wipe the inside with a paper towel, then wash with warm soapy water

That’s it! The cold makes the wax contract and loosen, so it basically pops right out. This is the go-to method for cleaning wax from candle jar without any effort at all.

Method 2: The Hot Water Method

If your jar has a lot of wax left or the freezer method didn’t get everything out, try the hot water trick.

Here’s what you do:

1. Boil some water and let it cool for just a minute (you want it hot, not boiling)
2. Pour the hot water into the jar, leaving a little space at the top
3. The wax will melt and float up to the surface
4. Let it cool completely — the wax will harden on top again as a solid disc
5. Just lift the wax disc right out!
6. Pour out the water, wipe the jar clean, and wash with soap

This works really well for cleaning a candle jar that has a thin layer of wax stuck to the bottom. Just be careful with very thin glass — pour slowly and don’t use boiling water straight from the kettle.

Method 3: The Oven Method (For Multiple Jars at Once)

Got a bunch of jars to clean at the same time? This one’s for you.

Here’s what you do:

1. Preheat your oven to 170–180°F (the lowest setting)
2. Line a baking tray with foil or parchment paper
3. Place your jars upside down on the tray
4. Put them in the oven for about 15 minutes
5. The wax will melt and drip out onto the foil
6. Use oven mitts to remove the jars — they’ll be hot!
7. Wipe the insides while still warm, then wash with soap

This is the fastest method if you’re doing a big batch. Perfect if you’re a candle maker cleaning out test jars, or if you’ve got a whole collection of finished candles to go through at once.

How to Remove the Label and Leftover Residue

Once the wax is out, you might still have a sticky label or a little oily residue inside. Here’s how to handle both:

For labels:

• Soak the jar in warm soapy water for 10–15 minutes
• Peel the label off slowly — it should come right off
• If there’s sticky glue left, rub it with a little coconut oil or olive oil, let it sit for a minute, then scrub off

For wax residue inside:

• Wipe with a paper towel while the jar is still slightly warm
• Then wash with hot soapy water
• For really stubborn spots, a tiny bit of rubbing alcohol on a cotton ball works perfectly

After this, your jar should look clean, clear, and almost brand new!

How to Do a Final Clean

For the last step of how to clean glass candle jars, give them a proper wash:

• Hot water + dish soap + a bottle brush or sponge
• Rinse well so no soap smell lingers
• Let them air dry completely upside down on a clean towel
• Hold them up to the light to check for any cloudy spots or residue

If they look crystal clear — you’re done! Your jar is fully clean and ready to use again.

What to Do With Your Clean Jars

Okay, this is the really fun part. Once you know how to clean out used candle jars, you’re going to stop seeing empty candles as trash and start seeing them as free supplies!

Here are some of the best ways to repurpose candle jars around your home:

• Pen and pencil holder on your desk
• Cotton ball or Q-tip holder in the bathroom
• Herb planter for a sunny windowsill
• Jewelry dish for rings and earrings
• Spice jar in the kitchen (great for small amounts!)
• Brush holder for makeup or paint brushes
• Mini vase for small dried or fresh flowers
• Storage jar for paper clips, hair ties, or buttons
