adespo could you put your location up on your profile ?

This way if in the future if you have certain questions relating to care, sometimes people in specific regions can help you with local knowledge.

Now, with the leaves, as Jerry said it is an ongoing problem and I only use rainwater on my orchids, and it leaves little or no residue.

I don't really worry about cleaning them unles I am entering them in my orchid club's competitions. When you have 50 plus plants it becomes a real chore.
