It can be cleaned off but I don't want it to harm the plant. What is that and why?

This depends on, exactly, how it looks. Two things come to mind. Powdery mildew (somewhat easy to get rid of) and Mealy bugs (Difficult to get rid of)

I will include articles for both, and general care of the plant:
