Regularly cleaning your dryer vents will reduce energy usage and drying time. Also, not cleaning your dryer vents could result in a dryer fire which is one of the most common reasons for home fires. So if your loads are taking more than one cycle to become dry or the top of the dryer is hot to the touch, it might be time for a cleaning.
First things first, make sure you have cleaned your lint trap and vacuum around the outside of it. Also keep in mind that it’s a good idea to clean off your lint trap after each use of the dryer.
Next take a lint trap vent brush and put it all the way down inside the vent and twist it around. Pull it out and clean all the lint off and repeat this step until there is less and less lint on the brush.
Now use a flat hose attachment on your vacuum cleaner and vacuum down inside the vent. This is what will pick up the most dirt and debris.
Disconnect the dryer ducts and unplug your dryer. Use a larger round duct brush to clean the inside. Making sure to twist gently and clean off the brush each time you pull it out. Do this until no lint is being left on the brush.
When you’re all done make sure to reattach everything and plug your dryer back in.
