Steps to Clean Bathroom Extractor Fan

Begin by turning the power off to your bathroom. This should be done at your main panel.

Then, you need to locate the bathroom extractor fan. Typically the fan will be found high up on the wall or in the ceiling. Keep in mind that not all bathrooms have this fan. If you have an exterior window, your bathroom might not have been designed with a fan. If you find that your bathroom doesn’t have a fan or a window, it would be wise to contact a professional to have one installed.

Use your screwdriver to loosen the screws that hold the cover in place. Be careful when removing the cover.

Once you locate the extractor fan blade, look to see if there are additional screws which hold it in place. If so, now is the time to remove them. Remove the blade whenever possible because it will be easier to clean. Also, be sure you put your screws in a safe place so you don’t lose any.

Start by cleaning the cover of the fan blade. Use soap and warm water. Wipe away all the debris and dirt so it doesn’t circulate with your fan and end up in your air. Then, clean the fan blade on both sides. Allow everything to dry completely before reassembling.
