As with anything that has a horizontal surface, Venetian blinds will collect dust, there is no getting around that. This is probably one of the main concerns or questions I get asked about this style of blind. Really it comes down to this, when you do the dusting in the rest of your house, you should really give your Venetian blinds a quick go over with the feather duster. As with anything, the longer you leave it, the harder the job will be. It doesn’t matter whether it’s cleaning the house, cleaning the car, mowing the lawn or cleaning your blinds, it’s the same story.
