What are best practices for burning my new Paddywax candle? Make sure you burn your candle for 3-4 hours the first time around. You want to make sure your wax pool extends to both ends of the vessel before extinguishing. This will avoid tunneling!​ You should also be sure to trim your wick to 2.5cm. How do I get the last of the wax out of my container so I can repurpose it? You can either A) put the candle in the freezer overnight and the wax should easily pop out the next day, or B) run hot water into the candle to melt the remaining wax so you can scoop it out.
