In the case of a dryer vent, make the effort to clean the machine’s lint filter after each load of laundry. This could help a great deal in keeping out fire-related incidents.
Appliance manufacturers also suggest that you do a yearly inspection of the dryer vent ducting system. Check the entire length and get rid of any lint build up. You can do this with the help of a brush designed specifically for this job.
If you have an exceptionally long dryer duct and you are not exactly sure how to go about this, seek the assistance of a professional.
Note that if any obstructions lurk in the vent and are left unattended, air flow to the dryer could be affected and this will consequently affect the drying time and lead to increased energy consumption. Also, if your dryer is overworking due tothe obstructions in the vent, it might end up malfunctioning pretty soon.
Lastly, remember to clean the lint screen on the regular and to never put soiled clothes, synthetic rubber, foam pillows, rubber coated sneakers or oil, gasoline or chemical impregnated material/ fabrics in the dryer.
