How to Remove Candle Wax from a Jar, and What to Do with Leftover Candle Wax

Once your candle burns down and your wick is gone, it can feel like a huge waste to just throw away your perfectly good glass jar. Why not remove the wax and re-use that jar for storage, or canning, or even for making another candle!

Removing candle wax from a jar can yield an array of benefits. For one, you’ll be able to salvage that small bit of wax that’s left over, and use it as a wax melt, or re-wick it and use it in a new candle. Another is that you’ll have a nice, clean glass jar that can be repurposed for almost anything. Let’s go over the steps, here’s how to clean candle wax from a jar, and what to do with the wax that’s left over.

How to Remove Candle Wax from a Glass Jar

Removing Wax from a Glass Jar with Boiling Water

There are actually a few ways to get that wax out of your glass jar, but the first we’ll go over is the most popular method: boiling water. Through this method, we’ll be able to quickly and cleanly remove the entirety of the leftover wax from your jar.

Just as heat melted your candle wax in the first place, we’ll utilize the same concept to remove the leftover wax, along with the wax’s natural buoyancy.

  1. Bring some water up to a light boil.
  2. Place your candle jar on a kitchen towel, and spoon out as much of the wax as you can.
  3. Gently –and carefully- pour your boiling water into the jar, leaving a bit of room at the top.
  4. After the water melts the wax, allow it to completely cool down. Since wax is naturally buoyant, it will float to the top of the water and re-solidify.
  5. Remove the wax that’s sitting on the top.
  6. Use a mesh strainer to remove any leftover wax floating in the water (you definitely don’t want any wax going down your kitchen drain!)
  7. Clean the jar with soap and water to remove any remnants.

Removing Wax from a Glass Jar Using the Freezer

If you’ve got a bit more time on your hands, and don’t want to mess around with boiling water, then this is the method for you. It may not remove the wax as cleanly as the boiling water method, but you’ll be able to complete this method a bit more passively.

  1. Use a butter knife or spoon to remove as much of the wax as you can ahead of time.
  2. Place your candle jar in the freezer overnight.
  3. In the morning, remove the jar from the freezer.
  4. Using a spoon, pop out the frozen wax.
  5. Scrape any remaining wax from the sides of the jar.
  6. Clean with soap and water to remove residue.

Removing Candle Wax from a Glass Jar Using the Oven

If you have several candle jars that you want to clean at once, then this method will be much more efficient than the other two. You can melt the wax from several jars at once, and save yourself a lot of time from boiling water or scraping frozen jars.

  1. Scrape out all of the wax you can using a spoon.
  2. Pre-heat your over to 185 degrees Fahrenheit.
  3. Line a baking sheet (Ideally an old one, or one that you don’t care about very much) with tin foil.
  4. Place the candles upside-down on the tin foil, and set the baking sheet in the oven.
  5. Set a timer for 15 minutes.
  6. Check back on your glass jars after 15 minutes, the wax should be melted by then, but feel free to give them a couple more minutes if needed.
  7. Remove the baking sheet from the oven.
  8. Let the jars cool down for a few minutes.
  9. Using a pot-holder, pick up your jars and allow the wax to drip out of the hole.
  10. Using a paper towel, wipe away as much of the wax as you can, being careful to not burn yourself.

Let the jars cool down, and wipe away the residue with soap and water.

What to Do with Leftover Candle Wax

Now that you’ve removed the leftover wax from your glass jars, you’re probably wondering what you should do with all of the wax you have! Here are a few simple ideas for how to use your leftover candle wax.

Make Wax Melts!

Simply cut up your leftover candle wax into manageable sizes, and place them on your wax melt burner. You’ve got tons of wonderfully scented wax, use it to scent your home wonderfully!

Fragrance Pouches

Similar to the wax melts, fragrance pouches are super easy to make. Just cut up your wax into smaller pieces and place the pieces into a linen pouch. You can place these little bags into your car, or your closet, or any other small space where you want to provide a nice fragrance.

Homemade Wax Seals for Letters

When is the last time you received a nice, handwritten letter? If you even remember, I’m sure it made you feel special and loved. Why not provide that feeling for someone else? Write a letter to your best friend, mother, spouse, or whoever, and let them know you appreciate them. Then, melt a bit of your wax onto the envelope and press on it with a cork or spoon to seal it tight. This extra bit of effort will make your letter feel even more personal, and it’ll smell fantastic too!

Make a Whole New Candle!

If you’ve got enough wax left over, you can insert a wick into one of your jars and melt the wax right back in, and you’ll have a whole new candle! It’s easy enough, it gets you a free candle, and you get to be proud of your own creation. Whenever anyone asks “Wow, where did that cool candle come from?” you can tell them that you made it yourself, and you’d only be lying a little bit.

But What Should You do with Leftover Candle Jars?

You went ahead and removed the wax out from your candle jars, and you re-used the wax with one of our methods above, but now what do you do with the empty jars?
