Dryer Cleaning and Fire Safety in Toronto
Clothes dryers are one of the leading causes of residential fires in Canada — the Ontario Fire Marshal's office consistently identifies dryer lint fires as among the most preventable causes of home fires. Lint is highly combustible, and a dryer duct that hasn't been cleaned annually or a lint trap that hasn't been cleared regularly provides the fuel for a fire that can start within the dryer unit itself and spread through the duct system into the home's structure. In Toronto's dense residential housing — semi-detached homes sharing walls, condo buildings where dryer vents run through common areas — dryer fires have an above-average potential for spread beyond the originating unit. The routine below is both a cleaning task and a fire safety measure.
The Lint Trap — After Every Load
The lint trap (the screen filter, typically located just inside the dryer door opening) should be cleared after every single load of laundry. This is the single most important dryer maintenance action. A full lint trap:
- Reduces airflow through the dryer, increasing drying time and energy consumption
- Causes the dryer to overheat (the thermal fuse, a safety device, trips when overheating occurs — if your dryer stops mid-cycle, a full lint trap is often the cause)
- Allows lint to bypass the screen into the duct system, increasing duct buildup over time
Clearing the lint trap takes 5 seconds. Do it after every load.
Deep Clean the Lint Trap — Monthly
Fabric softener sheets and liquid fabric softener leave a waxy residue on the lint screen over time that reduces airflow even when the screen appears clean. Monthly:
- Remove the lint trap screen
- Hold it under warm running water — if water passes through freely, the screen is clean. If it beads and doesn't flow through, there is residue buildup
- Scrub gently with an old toothbrush and dish soap under warm water
- Rinse thoroughly and allow to dry completely before returning to the dryer
Clean the Dryer Duct — Annually (Critical)
The exhaust duct running from the dryer to the exterior vent (typically through an exterior wall or upward through the ceiling) accumulates lint inside over time. Annual cleaning is essential for fire safety.
- DIY: A dryer duct cleaning kit (a flexible brush on an extendable rod — available at Canadian Tire, Home Hardware for ~$25–40) allows homeowners to clean the accessible length of duct from the dryer connection
- Professional dryer duct cleaning: A HVAC or dryer duct cleaning service can clean the full duct run including any bends or difficult sections — available in Toronto for $100–200 depending on duct length. Recommended when the duct run is long (>3 metres), has bends, or the dryer takes more than one cycle to dry a normal load
Signs the duct needs cleaning: laundry takes 2+ cycles to dry, the dryer runs hot to the touch, or lint is visible around the exterior vent opening.
Clean the Dryer Drum — Every 3 Months
The inside of the dryer drum accumulates fabric softener residue, crayon/pen marks (from laundry that went through with items in pockets), and general soil. Wipe the drum interior with a damp cloth dampened with rubbing alcohol — it removes most residues without leaving a water mark. For crayon or pen marks: a small amount of dish soap on a warm damp cloth, followed by a clean damp cloth rinse, then running the dryer empty for 15 minutes to ensure complete drying before the next laundry load.
