I have bought a wax tart burner and love it! The smell is lovely and strong and it's so easy.
But (and this is kind of a good thing) the tart lasts ages and I would kind of like to swap scents now and try something else for a bit. Is there any way to remove the solidified wax from the top, replace it with another tart for a while, and maybe swap it back in again later? I tried to dig out the edges with the end of a spoon but it didn't work at all ? TIA!
