You’ve got some awesome advice and suggestions here about smoke cleansing already- all I have to add that hasn’t already been mentioned is a simmer pot! It’s a method of cleansing/adding magick to the space that is much less “smokey” than many incense sticks, so it is a good option for those in smaller places (or places that aren’t well-ventilated, as breathing any kind of smoke can bring health hazards).
You can also customize it however you’d like and can use up leftover fruits that might otherwise go to waste 
Plenty of recipes out there too! It’s a great kitchen witch way of cleansing 
Here’s a recipe for one I made the other week → Seasonal Simmer Pot
Good luck with your cleansing and blessed be!
