Candles are a great way to add ambiance to a room while providing a pleasant scent in the process. They come in a variety of scents and colors to suit any scent or mood you want. But sometimes candle jars can start to turn black. It is unsightly and makes the candles look dirty, and they usually need to be thrown away. So what is going on and what can you do about it?


Why do candle jars turn black?

When you light a candle for a while and start to notice black crawling on the side of the jar, this is carbon at work. The flame produces carbon, and the bigger the flame, the more carbon there is.


The blackness you see in the jar is due to a lack of oxygen. The jar can only produce carbon without the necessary flow of oxygen, and then it burns. The updraft of these hot gases from the combustion starves the flame of oxygen and prevents the diffusion of air.


This causes a general burnt black appearance inside the candle. Unless you are an amateur candle maker, you may not be aware that there are actually proper ways to combat the burning of carbon that produces the black, burnt appearance we all hate so much.

Keep the jars clean

It goes without saying that you don't want the candle to burn before doing so, but try to cover the jar between uses. This is because leaving it open may mean that dust gets into the jar. When dust falls into the jar, it can and will burn. This can cause traces to be left on the side of the jar and the dust can burn into the air.


If you start to notice a build-up of dust in the jar, use a damp cotton pad to remove it. It is especially important to clean the top of the wax, as most of the heat will be concentrated in that area. All you need to do is use a damp cotton pad and some warm soapy water. Gently wipe the stained area until the black soot begins to appear and is eventually removed.


Make sure the area is completely dry before lighting the candle again. Once your candle is clean, you can refer to some of the helpful tips above to make sure your candle jar is free of soot and black debris.

Finally, you can reuse the candle jar. Even if the candle has burned completely, you can restore it to its normal working condition. All you have to do is pour some hot water into the glass and swirl it.


The hot water will break down any debris or wax left in the holder, and it will stay free and clean when you pour the water out. You can use those empty candle holders for pencils and pens, or even cute little flower pots. On the other hand, if you have leftover wax, you can use it with these ideas.
