Step 1 - Once candles are burnt and there is little to no wick and wax left, place the empty glass jar into your freezer.

Step 2 - Leave glass jar for 1-2 hours in your freezer.

Step 3 - Once frozen take each glass jar out of freezer and with a cocktail stick or the equivalent scrape the remaining wax, wick and any residue out of the jar.

Step 4 - Use a damp cloth to wipe jar clean followed by a drying cloth to dry.

Step 5 - Pop your refill into the jar and your candle is now ready to light. It is important to note you must allow the candle to burn for a minimum of two hours when first lit.
