Cleaned up my fan while detailing my Falcon2 Pro 40w. It needed it! One year’s use. Used a brush to knock the heavy stuff off and some compressed air. Then cleaned the surfaces with qtips and 99% IPA. Also blew out the exhaust hose with 100PSI compressed air. Do this with an N95 or respirator on. Don’t want to breath this dust. My fan is now a bit more quiet!
