How do you clean duct extractor fans?

Use a vacuum cleaner to clean out the duct of the extractor fan so that you can get rid of any clogs inside the duct. Put all of the fittings in a safe place so that they are easy to find when you need to put the fan on the wall again. Putting them in a bowel or on a towel will keep them safe.
