Always trim the wick and check for debris.

Before you light a candle, always trim the wick to ¼ inch and remove any debris left in the wax pool such as wick trimmings or matches.

Keep the flame away from moving air.

When burning a candle, avoid proximity to fans, air conditioners, open windows, or crowded areas with people walking back and forth. Moving air can disturb the flame, resulting in those pesky black marks on the glass.

Store your candles properly.

Store candles in a cool, dark and dry place with the lid on to keep them clean of dust and debris, and to help protect the wax and fragrance. Highly fragrant candles have a life span of 6 to 12 months, depending on the scent. If you enjoy fragranced candles, then use and replace them often to avoid deterioration in appearance and performance.
