While your cleaning, visualize the energy in the area that your cleaning being cleaned up and purified as well. Salt is also an excellent energy purifier. I have a glass of salt on my shelf in my bedroom and change it out every month. Usually when I'm cleaning I will wipe down things with salt water.
I have a rug in my bedroom... I vacuum it first and then sprinkle salt on the rug and vacuum it up later. Plants are a big air purifier and are good to cleanse the energy in a space. They help clean the air and make the room look nicer. Smudging with sage is also great with cleaning away the negative energy in a room or home.
I always open up my windows during storms and on those breezy days. I love watching the curtains sway in the breezes that come into the room. Rearranging furniture helps to move the energy around, also I would advise you to look into Feng Shui.
