How to Remove Candle Wax from Glass Jars: A Comprehensive Guide

Scented candle jars are often aesthetically pleasing, making them ideal for repurposing once the candle has burned down. Cleaning and removing the wax from a jar allows you to give it a new life as a decorative piece, storage container, or even a cocktail glass. This guide provides several methods for removing candle wax from glass jars, ensuring you can salvage those beautiful containers.

Why Remove Wax from a Candle Jar?

• Recycling and Repurposing: Cleaning out candle jars allows you to recycle and repurpose them, reducing waste and giving the containers a new function.
• Decorative Value: Many candle jars are attractive and can be used as decorative items in your home.
• Gifts and Sentimental Value: If the candle was a gift or holds sentimental value, cleaning the jar allows you to preserve it as a keepsake.

Methods for Removing Candle Wax

The removal methods below work on different types of candle wax, including paraffin, soy, or beeswax. You don’t need any special equipment or a ton of time-just a kitchen and some patience.

1. The Freezer Method: Cold as an Ally

Cold causes wax to harden and shrink, making it easier to remove. This method is quick, easy, and effective.

Steps:

1. Break up large pieces of wax: If the jar has a narrow mouth, use a butter knife or spoon to break up any large chunks of wax that remain in the container.
2. Place candle in freezer: Place the jar in your freezer overnight, or for several hours depending on the amount of wax.
3. Pop out wax: After the wax has frozen, remove the jar. The wax should pop right out of the container. If necessary, loosen it with a butter knife.
4. Clean the jar: Scrape off any residue and then clean the container with dish soap and water. Now wash the pot to give it a new life!

2. The Hot Water Method: Simple and Effective

This method is recommended for jars with thick glass. Using hot water melts the wax, allowing it to float to the surface. Caution: too thin glass - there is a risk that the glass will shatter.

Steps:

1. Remove as much wax as you can with a knife: Put the candle on a surface protected with a towel or newspaper. Use a butter knife or spoon to remove as much wax as you can.
2. Boil water: Boil water in a saucepan.
3. Pour boiling water into vessel: Pour the boiling water into the candle jar, leaving room at the top. Only fill the jar halfway as the wax will rise to the surface on its own. If your candle is made of a soft wax, such as soy wax, you can use hot water that’s not boiling.
4. Let stand: Let the mixture stand until the water is cold and the wax has risen to the surface.
5. Remove wax: Remove the wax. Strain the water to get rid of any small wax bits. (Don’t pour wax down the drain-it can create a clog.)
6. Clean the jar: Scrape any remaining wax and clean with dish soap and water. Your pot is now ready and you are free to use it according to your imagination in terms of decoration.

3. The Oven Method: For a Clean Candle Jar

The oven method is effective for cleaning multiple jars at once.

Steps:

1. Scrape as much wax as you can and preheat oven: Scrape out as much wax as you can with a butter knife or spoon. Heat the oven to 100°C (180 degrees Fahrenheit) and line a rimmed baking pan with aluminum foil or one or two layers of parchment paper.
2. Place jars in the oven: Place the candle jars upside down on the pan and set the pan in the oven.
3. Melt the wax: Keep an eye on it regularly as the time varies depending on the amount of wax in the jar. The wax will melt in about 5 to 15 minutes. Peek inside to see if the wax has melted.
4. Wipe out hot wax: Remove the pan and place it on a heat-safe surface. Remove the jar with a kitchen glove (before the wax hardens again). Hold the container using a towel or pot holder and wipe the inside with a paper towel.
5. Wash the jar: Let the container cool and then clean with soap and water.

4. The Double Boiler Method: Quick Wax Removal

Try this for quick wax removal.

Steps:

1. Remove easy-to-scrape wax: Remove as much wax as you can with a butter knife or a spoon.
2. Create a double boiler: Place the candle inside of a pot or large metal bowl on a heat-safe surface. (You can put a folded dish towel under the candle to keep it from moving in the pot.) Pour boiling water into the pot around the candle, making sure that the water does not get into the candle jar. Let the jar sit in the hot water until the wax has softened.
3. Remove container: Remove the container from the water, pop out the wax, and then wash with soap and water.

5. The Hair Dryer Method: An Alternative Trick

It’s not the most practical solution, but it’s another trick for removing wax from a candle in a jar that may be useful to know.

Steps:

1. Heat the wax: Hold your pot with an oven mitt and turn on your hair dryer to “hot.” Direct the hair dryer to the sides and bottom of the jar.
2. Scrape the wax: When the wax is softened, scrape it off with a butter knife.

Frequently Asked Questions

How do you remove candle wax without scraping it?

If you still have small bits of wax at the bottom of your container after using one of the methods above, you can pop it in the microwave for about 30 seconds. (Note: Be sure you have a microwave-safe jar before doing this.) Afterward, you should be able to simply wipe away any waxy bits with a paper towel, rather than having to scrape them with a knife.

How do you get all the candle wax to melt?

Patience is key, especially if you’re working with larger vessels-these will have to sit in the freezer or double boiler longer than small votive candles. If you have an area at the bottom of the jar with particularly stubborn wax, you can spot treat it with a hairdryer or heat gun. Just be sure to protect your hands by wearing an oven mitt and make sure you’re working on a heat-safe surface.

What can you do with empty candle jars?

• Kitchen Storage: Lidded jars are perfect for the kitchen. Use them to store spices, baking ingredients (like chocolate chips or marshmallows), nuts, or candy.
• Vanity Organizers: If your container doesn’t have a lid, place it on your vanity to hold makeup brushes or hair ties.
• Vases and Planters: Oversized vessels make great vases or succulent planters, and small votive containers work well on desks, holding paper clips or rubber bands.
• Cocktail Glasses: Food-safe containers, like glass jars, can even be used as cocktail glasses. In fact, candle brand Paddywax uses vessels made of Mexican bubble glass that are meant to hold margaritas long after the wick has been burned to the end.

How do you salvage a candle without a wick?

Here’s a bonus: Not only can you recycle your candle container, you can also reuse the wax-even if the original wick doesn’t survive.

• Mini Wickless Candles: One idea is to create mini wickless candles in fun shapes that you can then burn in a candle warmer. Pour the leftover wax into candle molds (Michaels sells heart- and gem-shaped molds), then add essential oils for subtle scents, and let them set. These are especially great if you have pets and prefer not to have an open flame but would still like an inviting aroma.
• DIY Tea Lights or Votive Candles: Another idea: Snag new, pre-waxed wicks from your local craft store and DIY tea lights or votive candles with the leftover wax. Insert your wicks into small heat-resistant cups and carefully add melted wax. To make sure your wicks stay in place while you pour, consider using wick centering tools. Once the candles have set, trim your candle wicks to around a quarter-inch. Voilà!
