Who has experienced the problem of dust buildup in the dryer vent? My dryer has started to run less efficiently and I've noticed the drying time has increased a lot. I'm trying to figure out how often I should clean my dryer vent and is there any way to do it myself without hiring professionals? Also wondering how dangerous it is to ignore cleaning - they say it can cause a fire, is this really the case? Share your experience, how you deal with this issue and how important regular cleaning is!
