Remove large crystals as they begin to expose the wax. Ensure the wick is not lit when doing so. Use a spoon or a similar object. Crystal will be hot. Handle with caution.
Or freeze the candle in the freezer - once it is finished, replace it in the freezer once it has cooled and is not melted or hot. Once frozen, remove crystals with a spoon more easily. Proceed with caution. Keep away from animals and small children.
Cut the wick when you see a mushroom-like top hours after putting out the flame to avoid the oil entering the air and turning into black soot.
