For the Venetian blinds you can do the same thing, use a duster on the end of your vacuum cleaner; a damp rag works best. These are normally at back doors so a lot of times the slots by the door become really dirty from the little kids touching them or the dogs scratching on the window and you can just use a wet rag and a multipurpose cleaner to get the dirty spots off. They also click out easily and you can put them in the bathtub, wipe them down on both sides, to dry and hang them back up when you’re done.
