Love this burner design as it comes with all separate parts. The burners has a total of 3 parts - the base, the body which contains the oil and a tealight holder. Just remove the holder to easily slip in the tea light or removed the used tea light without moving the burner at all. For cleaning, just remove the body and rinse under water. I have recently bought the cleaning solution so that it can help removal of stubborn stains easily.
