#8: Clean Your AC Vents Using Your Dishwasher
Check your air conditioning vents to see the accumulated grime. While cooling, these systems trap dust, animal hair, and skin flakes, affecting their efficiency. A peek inside might reveal a less-than-pleasant view of what’s circulating.

For an easy clean, unscrew and place your vents in the dishwasher on a cool cycle, sidestepping tedious handwashing. Afterward, blow dry off the excess water—a simple trick for maintaining a cleaner, more efficient air-con system.
