Our concrete jars are made to be repurposed. Gently scrape and scoop out the remaining wax. Be careful not to scratch or damage the concrete surface. Fill the vessel with hot, soapy water (not boiling!) and let it soak for a few hours. This helps loosen any residual wax or debris. Use a soft brush, sponge, or paper towel to scrub the inside of the vessel, removing any remaining wax or residue. Rinse thoroughly with clean water. Allow the vessel to air dry completely before repurposing it. Now that your concrete candle vessel is clean, you can repurpose it as a plant pot, a pen holder, or a bathroom organizer!
