I agree with all the replies for keeping instruments in good condition. I have a Pa1X Pro. I would like to add a few things I do. I feather dust my keyboard every day. Feather dusting with a good ostrich feather duster works great for removing dust from around buttons etc. My feather duster is only used for my musical equipment. I wipe my keyboard (buttons, keys and display) with a slightly damp washcloth and wipe it dry with an old cotton T shirt first thing every day. Every couple months I vacuum gently with the vacuum brush.
