I got lucky this year. My sister-in-law gave me a Scentsy candle warmer for Christmas. (I didn't even know what a Scentsy candle warmer was until November, but that's beside the point.) I was/am super excited!
But at the same time, I was a little sad because Scentsy doesn't have my all-time favorite candle sent: Grapefruit Vanilla. And what was I supposed to do with my precious candle? Throw it in the garbage?
First, I melted it down using a candle warmer. (Yeah - it took forever; one of the reasons I'm super excited to make the switch to my Scentsy warmer.)
Then I poured it into an ice cube tray, and set it in the freezer for about 20 minutes for it to harden. To remove the wax, I just wrung the tray over a paper towel and the cubes popped right out. (If you'd like to do the same, don't skip the freezer; it's the key to removing the cubes with ease.)
I got excited, and did the same to every candle in the house! Let's just say Justin is happy I've settled on one scent for a while...
***ETA: Apparently, I've upset some people. When I posted this DIY idea I had no idea of the amount of traffic that it would generate, and I had zero intentions of hurting sales of any company or self employed persons, and I apologize!
For the record, I am a Scentsy customer. I really love their wax and this idea was just a way for me to use up some of my favorite scents already on hand. Unfortunately, I didn't know about the lifetime warranty of my Scentsy warmer, or the fact that using any wax other than from their company voids that warranty.
Also, for those of you who own other warmers or (taking the above into consideration) still want to try this trick, I haven't had any issues with the couple of Salt City candles I "converted." They have melted fine at the low heat, smelled great, and wiped out of my warmer just as easily as the Scentsy wax I regularly use.
