Cleaning used candle jars allows you to reuse them for storage, decor, or crafts, giving them a second life. You can easily remove leftover wax and residue using several methods.
One effective approach involves melting the remaining wax. As noted in one technique, "I like this the most because it loosens up the adhesive on the sides. And the bottom. So it's like a two-for-one situation as it's melting you can see the wax melt on the sides." This method is particularly useful for removing stubborn wax and loosening any adhesive used for wicks or labels.
Popular Methods for Cleaning Candle Jars
Here are some common ways to clean out leftover candle wax:
1. The Melting Method (Using Heat)
This technique uses heat to melt the wax, making it easy to pour out. It's great for loosening wax and tackling stubborn adhesive.
- Steps:
- Place the candle jar on a heat-safe surface, like a baking sheet lined with foil or parchment paper.
- Warm the jar gently. You can do this in a low oven (around 150-170°F or 65-75°C) for about 15-20 minutes until the wax is melted. Alternatively, you can use a double boiler method by placing the jar in a pot of simmering water, ensuring water doesn't get into the jar. A heat gun can also be used carefully.
- As mentioned in a reference, this heat helps significantly because it "loosens up the adhesive on the sides. And the bottom." You'll notice this "two-for-one situation" as the wax melts and residue detaches.
- Carefully remove the warm jar (use oven mitts!).
- Pour the melted wax into a disposable container (like an old tin can or paper cup – never down the drain).
- Wipe out any remaining wax residue with a paper towel while the jar is still warm.
- Proceed to clean with soap and water (see below).
2. The Freezing Method
Cold temperatures cause wax to shrink and harden, making it brittle and easy to remove.
- Steps:
- Place the candle jar in the freezer for several hours or overnight.
- Once frozen, the wax should shrink away from the sides of the jar.
- Use a knife or spoon to gently break up and lift out the hardened wax. It should pop out relatively easily, often in large pieces.
- Clean any remaining residue with soap and water.
3. The Hot Water Method
This simple method uses boiling water to melt the wax.
- Steps:
- Place the candle jar on a protected surface (like a pot holder).
- Boil water.
- Carefully pour the hot water into the jar, leaving about an inch of space at the top. The hot water will melt the wax, causing it to float to the surface.
- Let the water cool completely. The wax will solidify into a disc on top of the water.
- Once cooled, remove the solidified wax disc.
- Pour out the water (again, avoid pouring wax down the drain).
- Scrape out any small remaining bits and clean with soap and water.
Removing Residue
After removing the bulk of the wax using one of the methods above, there might be some leftover residue or wick adhesive.
- Use warm, soapy water and a sponge to wash the inside and outside of the jar thoroughly.
- For stubborn residue, a plastic scraper or the back of a spoon can help.
- Rubbing alcohol or Goo Gone can be effective for removing sticky adhesive spots.
- Wash again with soap and water and dry completely.
By using these methods, you can easily get your used candle jars sparkling clean and ready for their next purpose!
