I have had some success spraying with 70% rubbing alcohol. It takes repeated treatments but is otherwise "friendly" as far as I know. Another treatment I tried was with Melaleuca Tough and Tender. I sprayed it on at the recommended dilution for cleaning. The scale fell right off and the leaves looked nice afterwards but I think it dries them as I do sometimes get leaf drop after treatment. My experience is limited so if you want to try either of these treatments, I would recommend just spraying a couple of test plants that you can spare.
