How to Clean a Dual Window Fan

Dual window fans sit unassumingly in windows, wedged between sashes and sills, helping to circulate air in and out of houses on hot, summer days. Over time, particles in the air being sucked through the fan start to accumulate on the fan's parts, including the blades and grill cover. The matter starts to stick, creating unsightly grime. Maintain a healthy environment and clean system of circulating air by regularly cleaning the window fan. Reaching the grime on interior parts requires disassembling the fan.

  Unplug and take the fan from the window. Place it faceup on a plastic-covered work surface.

  Pick up and remove any loose matter from the fan parts, such as lint buildup or pet hair, with a paper towel.

  Create a solution of hot water and mild, all-purpose cleaner, in a clean plastic tub.

  Dip a sponge or rag into the solution. Squeeze it out and wipe down all fan parts inside and out, including the blades, grate, panel and knobs. Scrub inside the holes in the grill grate with the solution, using a tube cleaning brush.

  Dampen a new sponge or rag in plain water and wipe down the fan a second time to remove any residue.
