1. Remove Remaining Wax
Once your candle has about 1/4 inch of wax left, it’s time to refill. To clean out the old wax:
Fill the vessel with hot (not boiling) water—just enough to cover the wax.
Let sit for 15–20 minutes until the wax rises to the surface and solidifies.
Gently pop the wax out and discard.
Wipe the inside clean with a paper towel or soft cloth.
⚠️ Important: Do not use boiling water—extreme heat can crack the concrete. If the water feels too hot to touch, it’s too hot for the vessel.
2. Insert Your Refill
Unwrap your KGB wax refill.
Place it directly into the clean, dry concrete vessel. It should fit snugly—no adhesive needed.
Trim the wick to ¼ inch before lighting.
