Im not saying its not, but its worked for me more than a few times without any bad effects. Just a strip of paper towel like 3"x1" moistened then squeezed out taped to the top. Also, orange peels can mold pretty quickly depending on the age of the orange and the organic material breaking down. Plus, I just dont like the citrus scent and taste the peels leave.

But if you dont mind the taste and smell, go buy some fresh oranges and youre set.
