I keep mine covered with a micro fiber or silk cloth this way not really any dust to remove. If left exposed I always blow off dust first with keyboard duster. Then use a Flitz micro fiber cloth and spray called Plexus.
Keeping dustcover looking new
Just bought a new dustcover for my TT ,love the clean,shiny, no swirl-mark look. Any tips on keeping plexiglass looking good?. In the past I would lightly dust with Windex,but over time the hazy swirl marks inevitably appear. What do you recommend to protect a new DC? Ive heard car wax, Armorall, rain-x, etc. Any ones experience is appreciated.
