While it’s impossible to completely prevent clogging, you can minimize the chance of it happening with a few simple actions.
Every time you dry laundry, remove lint caught in the lint trap. The secret is to do this before you run a cycle to reap the benefits of more efficient drying. Another tip is to go easy on the dryer sheets - these can cause blockages.
And, of course, staying on top of cleaning the dryer vent can also reduce the chance of clogs.
