It's not needed. As a few posts said, they don't get cleaned in nature. But if you just emulate nature, you might never fertilize either.
I try to "clean" the leaves when I re-pot, bring a blooming plant inside, or if I were to ever take a plant to be judged (never have). It's mostly an aesthetic issue.
