How to Properly Clean and Reuse Your Candle Jars for Eco-Friendly DIY Projects

At Mitala Candle Co., we believe in sustainable living and making the most out of every item we use. Candles are not only a source of light and fragrance, but their containers can also have a second life long after the candle has burned down. Your beautiful jar can be repurposed in countless ways—whether it’s as a chic planter, a gift holder, or even as a stylish new candle holder. But before you dive into your next DIY project, cleaning your candle jar properly is essential to ensure that it’s ready for its second life.

In this step-by-step guide, we’ll walk you through how to clean your candle jars, so you can easily reuse them for your next creative venture. Let’s dive in!

Step-by-Step Guide: How to Clean Your Candle Jars

1. Gather Your Materials

To clean your used Mitala Candle jar, you’ll need a few simple tools. Here’s what you’ll need:

  • A spatula or butter knife
  • Hot water
  • Dish soap
  • Reusable soft cloth
  • Oven mitts (if using the oven method)
  • Baking sheet (for oven method)

2. Remove Any Remaining Wax (3 Methods)

Option A: Freeze and Pop
Place the jar in the freezer for 1 hour. The wax will shrink and pop out easily when pried gently with a butter knife.

Option B: Boiling Water Soak
Fill the jar with hot water and let it sit for several minutes. The wax will melt and float to the surface. Once cooled, remove the wax disc and pour out the water.

Option C: Oven Method (Best for Stubborn Wax)

  • Preheat your oven to 200°F (93°C).
  • Place your candle jar upside down on a baking sheet lined with parchment paper or foil.
  • Heat for 15 minutes to allow the wax to melt and drip out.
  • Use oven mitts to remove the jars and carefully wipe them clean with a paper towel or cloth while they’re still warm.

Pro Tip: Save any leftover wax bits for a future DIY candle project!

3. Clean the Jar with Hot Water

Once the wax is removed, wash your jar with warm water and dish soap. Use a soft cloth or sponge to remove any soot or fragrance residue. Be sure to avoid harsh scrubbing, which can damage decorative finishes.

4. Dry the Jar

After cleaning, thoroughly dry the jar with a soft reusable cloth or let air dry. Make sure it’s completely dry before repurposing it, as moisture can interfere with some DIY projects.
