Candle jars are often too beautiful to throw away, and with a little effort, you can clean them out for reuse. The fridge method is one of the easiest and safest ways to remove leftover wax from a candle jar without using heat or sharp tools. By cooling the wax, it hardens and contracts, making it simple to pop out. This method is ideal for glass jars and works well for most types of candle wax, including soy, paraffin, beeswax, and coconut wax. Below is a step-by-step guide to help you clean your candle jar effectively.
Why Choose the Fridge Method?
The fridge method is popular because it’s:
-
Safe: No open flames or boiling water required.
-
Simple: Minimal tools and effort needed.
-
Clean: Leaves little mess compared to melting methods.
-
Eco-friendly: Encourages reusing jars for storage, decor, or new candles.
What You’ll Need
-
A used candle jar with leftover wax
-
A refrigerator or freezer
-
A butter knife or spoon (optional, for stubborn wax)
-
Dish soap and a sponge
-
A cloth or paper towel
-
Warm water
Step-by-Step Guide to Removing Wax Using the Fridge Method
Step 1: Prepare the Candle Jar
Ensure the candle has been extinguished and cooled completely. If the wick is still attached, gently remove it from the base if possible, or trim it down to make the next steps easier. Remove any debris, such as matches or wick trimmings, from the jar.
Step 2: Place the Jar in the Fridge
Put the candle jar in the refrigerator. For best results, place it upright on a stable shelf. Let it sit for at least 4–6 hours, or overnight for larger jars or thicker wax layers. The cold temperature will cause the wax to harden and shrink, pulling it away from the jar’s walls.
Tip: If you’re in a hurry, you can use the freezer instead, which will speed up the process to about 1–2 hours. However, avoid leaving the jar in the freezer too long, as extreme cold can occasionally cause glass to crack.
Step 3: Remove the Jar and Check the Wax
Take the jar out of the fridge. The wax should appear solid and may have visible cracks or gaps around the edges. Gently tap the jar on a soft surface (like a folded towel) or tilt it upside down. In many cases, the wax will pop out in one piece due to the contraction.
Step 4: Remove Stubborn Wax (If Needed)
If the wax doesn’t come out easily, use a butter knife or spoon to gently pry it out. Start at the edges where the wax has pulled away from the glass. Be careful not to scratch the jar. Any small wax bits can usually be nudged out with your fingers or the utensil.
Step 5: Clean the Jar
Once the wax is removed, wash the jar with warm water and dish soap to remove any wax residue, oils, or soot. Use a sponge or cloth to scrub the interior thoroughly. For sticky spots, a mixture of equal parts water and white vinegar can help. Dry the jar with a clean cloth or let it air dry.
Step 6: Repurpose Your Jar
Your clean candle jar is now ready for a new life! Use it to store small items like spices, craft supplies, or toiletries, or turn it into a planter, vase, or even a new candle by adding a wick and fresh wax.
Tips for Success
-
Check the Jar Type: The fridge method works best with glass jars. Metal or plastic containers may not respond as well to temperature changes.
-
Avoid Force: If the wax doesn’t come out easily, return the jar to the fridge for another hour rather than forcing it out.
-
Remove Labels: If the jar has adhesive labels, soak it in warm soapy water after wax removal to peel them off easily.
-
Wax Disposal: Place the removed wax in a compost bin if it’s natural (like soy, beeswax, or coconut wax) or wrap it in paper and discard it if it’s paraffin.
Conclusion
The fridge method is a hassle-free way to clean out candle jars, making it perfect for anyone looking to repurpose their containers without mess or risk. With just a few hours in the fridge and some light cleaning, you’ll have a sparkling jar ready for your next project. Try it out and give your old candle jars a new purpose!
