What are some of the best tools and techniques for dusting house fast and efficiently when you have lots of knick knacks –besides getting rid of them :)

Unfortunately I don’t think there’s any easy way to do this! I would make it a weekly thing to take all of them off of their dresser/ table etc dust each one individually- dust the table and wash or shake out the dust from the placemats/ table cloths. Then place them back.
The only other option (but wouldn’t be as thorough) would be to take a swiffer duster and go over them. Swiffer works pretty well.
