The fastest way to clean and declutter your home is the way that makes you your most efficient. If you aren’t sure what this is yet, time yourself cleaning your house by the room, and then time yourself cleaning by task. See which one was quicker and use that method when you clean your house in the future. This is just one example, but you can make efficiencies in every aspect of your chores. This is a Japanese method of Kaizen - ‘to make continuous improvements'.
