I have a small obsession with candles (with a penchant for the vanilla and lavender kind) and I've accumulated quite a number of empty candle jars. I was browsing Pinterest not too long ago and found this quick and handy guide on how to clean residual candle wax from candle jars. From personal experience, I've tried a number of DIY's on pinterest that turned out not so well but this one definitely works and best of all, its easy. Now my cotton balls have a pretty new home. Definitely try this out, it works great with the candle jars from Bath and Body Works.
