How to Clean Candle Jars – Easy DIY Methods to Reuse Them!

If you’re a candle lover, you know the struggle — you burn a gorgeous candle down to the last flicker, and then… you’re left with a beautiful jar full of leftover wax and soot. Don’t toss it! Your candle jar can be reused in countless creative ways — from mini planters to bathroom organisers.

In this post, we’ll walk you through how to clean candle jars easily and safely so you can give them a second life!

🧽 What You’ll Need:

• Boiling water
• Dish soap
• Spoon or butter knife
• Freezer (optional)
• Paper towels or microfiber cloth
• Cotton pads/Q-tips (for detailing)
• Rubbing alcohol or white vinegar (for residue)

✨ Method 1: The Boiling Water Method (Best for Glass Jars)

1. Scrape out large wax chunks using a spoon or knife.
2. Pour boiling water into the jar, leaving an inch at the top.
3. Wait as the wax melts and floats to the surface. Let it cool for an hour.
4. Pop out the wax disk once hardened.
5. Wash the jar with warm soapy water, and wipe with rubbing alcohol for a final clean

📝 Pro tip: Pour the wax into the trash, not your sink — wax can clog drains!

❄️ Method 2: The Freezer Method (No Mess!)

1. Pop the jar in the freezer for a few hours.
2. Once the wax contracts, use a spoon to gently pry it out.
3. Clean leftover residue with hot water and soap.
4. Wipe down with a cloth soaked in white vinegar for any fragrance stains.

♻️ Bonus: Remove Labels & Stickers

• Soak the jar in warm soapy water for 15–30 mins.
• Use a scrubber or your fingernail to peel off the label.
• Sticky residue? Use a few drops of oil or rubbing alcohol to remove glue.
