What is that stuff in the bottom of the candle?
Many people and certain ear candle manufacturers claim that ear candles extract ear wax by suction from the burning candle but this is not the case. The majority of what you see remaining in the bottom of the ear candle after it’s use is either melted paraffin or beeswax. If you don’t have a very good seal at the ear you may get a lot of brown, white, or yellowish powdery residue inside the candle, which is actually vaporized wax.
