How to clean a fan?

What is the best way to clean a fan

Hey there,

Me I used to use a can of compressed air and use like a tooth pick to keep the fan from spinning, not sure if it would have damaged the fan. Now I use a pancake compressor with a low PSI and still use a tooth pick to keep it from spinning. If you remove power and open it up you can also use a toothbrush that works good too.

Hope that helps

Thank you Roger.
