When your Glade candle runs out to the bottom. Soak it in hot soap and water, then clean it out and you can reuse as a votive candle holder.
I have a package of votives and the candle using can continue. SO don’t throw out the used glass jar, reuse it!!
Plus there are other uses. It can be a place to hold the house/car keys. Or for office supplies like clips.Plant a small flower in it! And I am sure you can think of other uses along those lines.
