This typically happens when you don’t let a candle burn long enough the first time you use it.
It can also be an indication that your candle wick isn’t large enough for the container.
Either way, it’s nearly impossible to reverse once it starts.
Neither of these messy techniques was very successful, and it left us with lumpy, unattractive wax surfaces.
However, we recently discovered a genius candle-melting hack using aluminum foil that totally changed the game.
After a couple of hours, the wax should melt and even out the surface.
For larger candles, verify the flame can still burn strongly and create enough heat to melt the wax.
If you are using a hair dryer, be sure to set it on high heat and low speed.
