Good sound track, focus on one area at a time and take breaks occasionally if you are doing a deep cleaning.
What is the most productive way to clean your room?
Sweep all the junk on the floor in a pile and sort lol.
Mark Twain came up with the best method when Tom Sawyer had to whitewash a fence. He got somebody else to do it.
Can't you trick a smaller sibling into doing it for you?
By not making a big mess in the first place. Pick up after yourself and put things back from where you get it. You'll never really have to spend an entire day cleaning.
Put on some music if you want to.
