For a short, accessible vent run, cleaning a dryer vent is a job many Melbourne homeowners can do themselves with an inexpensive brush kit — and doing it regularly keeps the dryer safe and efficient between professional cleans. This guide walks through the process step by step, covers how often to do it, and explains where the DIY limit is and when to call a professional instead.
What You Need
The basic equipment for a DIY dryer vent clean is:
- A dryer vent brush kit: a long flexible brush with extension rods, often designed to attach to a cordless drill so the rotating brush scrubs the duct walls. Inexpensive and available from hardware stores.
- A vacuum cleaner: to remove the loosened lint from the duct, the dryer outlet and the lint screen housing.
- A screwdriver or nut driver: to release the duct clamps and, if needed, the external vent cover.
- A cloth and gloves: lint is messy; gloves and a drop cloth keep the job tidy.
This kit handles a short, accessible vent run. If your vent is long, runs through the roof, or you cannot reach both ends, that is the point to call a professional instead.
Cleaning the Lint Screen
The lint screen is the part you clean most often — after every single load. Pull it out, peel off the layer of lint, and refit it. This simple habit removes most of the lint before it can enter the duct, and skipping it is the fastest way to a clogged vent and an overheating dryer.
Every few months, give the screen a deeper clean: wash it in warm soapy water with a soft brush to remove the invisible film that fabric softener leaves behind, which can restrict airflow even when the screen looks clear. Let it dry fully before refitting. Also vacuum out the screen housing — the slot the screen sits in — where lint collects.
Cleaning the Vent Duct Step by Step
- Unplug the dryer at the power point and pull it out from the wall to access the duct.
- Disconnect the duct from the back of the dryer and from the wall or discharge point, releasing the clamps.
- Brush the duct: feed the vent brush through the duct, rotating it (by hand or on a drill) to scrub the lint from the walls. Work from both ends if you can reach them.
- Vacuum the loosened lint from inside the duct, the dryer’s outlet, and the wall opening.
- Clean the dryer outlet — the vent opening on the back of the machine — where lint also gathers.
- Reconnect everything securely, making sure the clamps are firm and the duct is not crushed or kinked behind the dryer.
- Test: plug in and run the dryer, then check for strong, warm airflow at the external vent. Weak airflow means lint remains — or the run is longer than a brush kit can clear.
Cleaning the External Cover
Do not forget the external vent cover — the fitting outside where the duct discharges. Lint commonly builds up around the flap or louvre, and a cover jammed with lint is itself a blockage, stopping the flap opening fully and trapping the exhaust air. Check it from outside: with the dryer running, the flap should open and air should flow freely.
Clear any lint from around and behind the cover, make sure the flap moves freely, and confirm nothing has nested in it. On a wall vent this is easy; on a rooftop vent it means roof access, which is a job for a professional. A clean, freely operating cover is essential to the whole vent working.
How Often to Clean
The routine is simple: clean the lint screen after every load, and clean the vent duct at least once a year — more often with heavy use, such as a large household or frequent drying through Melbourne’s damp winter, where every six months may be warranted. Between cleans, let the warning signs guide you: if drying times lengthen, the dryer or laundry runs hot, or the external airflow weakens, clean the vent then rather than waiting for the schedule.
Sticking to this routine prevents the lint buildup that causes both the fire risk and the higher running costs of a clogged vent. See our fire safety guide for why it matters.
When to Call a Professional
DIY cleaning is fine for a short, accessible vent. Call a professional when:
- The vent run is long, runs through the roof, or is otherwise hard to access.
- The vent is heavily or fully blocked and a brush kit will not clear it.
- You cannot get strong airflow from the external vent after cleaning.
- The ducting is damaged, crushed or disconnected and needs repair.
- You are not confident reaching or reconnecting the duct safely.
A professional has the rods, rotary brushes and vacuum equipment to clear the entire run and confirm the discharge is flowing — which matters most for the long, awkward vents that pose the greatest fire risk and clog the worst. See our cleaning cost guide, or call FreshDuct on 0431 918 137.
