Tips to Avoid Wax Buildup in the Future

   • Use holders that match the size of the candle to minimize wax sticking to the sides.
3. Burn Candles Evenly:
   • Allow the candle to burn until the entire top layer is liquid before extinguishing.
   • This prevents tunneling and reduces wax buildup.
4. Avoid Drafts:
   • Do not place candles in drafty areas to ensure an even burn.
5. Cool Before Cleaning:
   • Always let the candle jar cool before attempting to clean it.

Eco-Friendly Disposal of Removed Wax

Once you have removed the wax, consider eco-friendly disposal or reuse. Here are some ideas:

Reuse Wax for New Candles

• Let them harden and use them in a wax warmer.

Create Fire Starters
