Blinds are such a pain to clean. Once a year I give mine a bath to really freshen them up. But for regular cleaning, I use a pair of kitchen tongs. Get 2 microfiber cloths. Fold them over and wrap one around each arm of the tongs so the metal ends are covered. Secure with a rubber band. Clasp each individual blind with your fabric covered tongs and wipe from side to side. Dampen with vinegar water if the blinds are really dirty. You can easily swap the cloths around to finish with a dry wipe.
