Window ac units can be a real pain to clean. If you’re looking for an easy way to do it without removing the unit, try this:

  1. Pour a pot of hot water into the unit and turn it on to full blast.
  2. Place a large towel or cloth over the window and wait until the water is hot before using it to clean the window.
  3. Wipe down all of the surfaces of the ac unit with the towel, being sure to get into all of the nooks and crannies. ..
