Yes, bathroom exhaust fans should definitely be part of your regular cleaning routine, though not every week. Over time, steam pulls dust and tiny particles into the fan cover, and they stick there. This reduces airflow and makes the fan work harder, sometimes with more noise and less actual performance.

A good pattern is to clean the fan cover every 3–6 months. Turn off the power, remove the cover carefully, and wash it with mild soap and water. Let it dry fully before reinstalling. While the cover is off, gently vacuum or brush away dust from the visible parts of the fan housing. You don’t need to dig too deep, just take off the obvious layer.

A clean fan does a much better job of pulling out moisture after showers, which helps prevent mould on walls and ceilings. People often scrub tiles and toilets but forget the one device that actually removes humid air.

So, yes — include it in your “bigger clean” list. A few minutes twice a year keeps the fan useful and your bathroom drier and healthier.
