How to Clean an Outside Dryer Vent

When was the last time you went outside to inspect the dryer vent cover on a house exterior wall to see how well it was opening? It probably isn’t on your list of regular chores, but it ought to be.

The second leading cause of home fire damage, behind kitchen fires, is fires that start in lint-clogged clothes dryers. The main causes of laundry room fires are accumulated lint and dust, far more frequently than wiring issues or other problems. A properly installed and maintained dryer vent system is equally important to enhancing the performance of your dryer and preventing fires as emptying the dryer lint screen after each load.

Most dryer vent systems that are installed and adhere to building code requirements end at an exhaust escape vent on an exterior wall or roofline. In order to ensure dryer efficiency and safety as well as to avoid structural moisture issues, the outside dryer vent must be kept clean. The majority of exterior dryer vents have hinged “doors” or slats that swing open when the dryer is on to let moisture and lint out. The moisture will stay in the dryer venting if these get clogged with lint, which will make your dryer work harder. In case a load is taking your dryer an increasing amount of time to dry, check the outside vent. Mold and mildew can also develop on the walls and floor of the laundry room due to moisture and the presence of lint.

To improve the airflow in your dryer, the exterior dryer vent needs to be cleaned and inspected every three months. This will shorten the time it takes for laundry to dry and aid in keeping your home dry.

What You Need


  • Bucket
  • WD-40 or another type of lubricant
  • Dishwashing liquid


  • Long-handled wire vent brush
  • Scrub brush or old cloths


Check the Vent Opening

While the dryer is running, check the exterior vent to ensure the slats are moving freely. Turn off the dryer and manually open the vents if they are not opening properly.

Inspect the Vent

Check the hinges for rust and give them a light lubricant if necessary. Additionally, look for any cracks or components missing from the vent. Nobody wants vermin and insects getting into their laundry room or ductwork because of missing parts.

Remove the debris and lint

Use your hands or a long-handled wire brush to get rid of clogging lint. Regular cleaning is especially crucial in humid climates, where moisture can cause lint to mat and cling to the vent, causing it to malfunction.

Wash the Vent Cover

Clean the vent cover with a brush or an old cloth if it is covered in dust and grime by combining a few drops of dishwashing liquid in warm water. Rinse thoroughly with fresh water and let dry.

How to Choose the Best Dryer Vent Cap

Indoor Dryer Vent Kit

Despite the popularity of buying indoor dryer vents, some precautions should be taken when using them. The best option for managing room temperature in an interior setting is to use an indoor dryer vent. However, they can be somewhat unsafe. If possible, the dryer should be allowed to vent all moisture to the outdoors. Apartments and condominiums with limited space may be better suited to indoor dryer vents. Mechanical codes and manufacturers recommend regular servicing to prevent mold from growing inside dryer vents.

Outdoor Dryer Vent Kit

These vents can be used for small and large spaces because they are designed according to the local codes and regulations. Compared to indoor dryer vents, they are safer because they are built with the metal of at least 04mm. An exhaust duct should be placed within 35 feet of the wall’s endpoint, and the distance should be as short as possible. Because it exits outside, these models are safer than indoor dryer vents. An outdoor dryer vent has a lower fire risk.


Manufacturers of dryer vents should disclose the duration of their warranties. It is better to have a longer warranty in case of a return or repair of the product.


Various dryer vent kits depend on the dryer model’s speed and efficiency. In general, bigger and sturdier machines can be used in larger areas that require more venting due to their size and weight. Are you required to buy a dryer vent kit that is industrial-grade? You should take that into account as well. There is minimal lint buildup in rigid dryer vents, making them safer and cleaner than flexible dryer vents. Metal and flexible plastic combos require greater maintenance and cleaning than metal and rigid plastic. It is also possible for flexible dryer ducts to be crushed, which can result in blocked airflow and the dryer overheating.

Build Quality

After evaporating water in clothes dryers, they generate large amounts of vapor released into the air. Many different types are available such as hard plastics, metals, or a combination of plastic and metal. Furthermore, they can be classified based on whether they release the vapor inside or outside, away from the house. A model made of metal is rigid, durable, and longer-lasting. Plastic vents are susceptible to twisting and crushing in the space where the vents enter the wall and exit the dryer. You might need a dust collector to clean up excess dust and debris if the build quality isn’t up to scratch.


In order to stop house fires caused by drying houses or excessive fumes produced by dryers, some steps should be taken during the use and installation of dryer vents. Cleaning and maintenance of lint should be done properly and regularly. Verify if any bird activity has occurred at the dryer’s termination port and remove debris. Check the speed of air leaving the dryer vent. If the air rushes slowly or is blocked, the dryer vent needs to be cleaned to remove lint and other debris, which may cause a fire. This can be ensured by giving adequate space behind the dryer, so the flex transition hose does not get crushed.

Buy the Best Dryer Vent Kit

What kind of dryer vent cover do I need?

Decorative dryer vent covers allow lint and dryer air to escape when necessary while keeping your home airtight. Birds and rodents cannot build nests under the cover or block airflow.

How should I choose a dryer vent?

For enclosed ducting, metal (galvanized or aluminum) must be rigid with a minimum diameter of 4 inches. Flexible ducts between the dryer and outlet should be either foil or aluminum (most preferred). Plastic and vinyl should not be used.

Flexible dryer vents are they safe?

It is easy to install flexible foil ducts because they are pliable. Most hardware stores carry foil ducts that are UL listed. Almost all building codes and appliance manufacturers forbid these ducts since they’re unsafe and more likely to burn than foil ducts. Some dryer warranties will be voided when transition ducts are made of white vinyl.

Is every dryer vent 4 inches long?

There are usually four inches of diameter on dryer ducts. There are rigid and flexible types of people. Occasionally, vinyl duct, as well as the flexible duct in general, is prohibited by building codes. There are also models of dryers that may come with specific ducting specifications.

Why do old dryer vents need to be covered up?

Place a chunk of blanket insulation in the hole using a straight edge and a utility knife. It will need to be pressed down a bit and then fluffed out. A complete insulation fill should not protrude from the sides.


When shopping for the best dryer vent cap, make sure that you think beyond the initial purchase price. Keeping your furnace warm in winter and preventing pests from getting in your dryer vents are all possible benefits of properly installed and maintained dryer vent covers.

Our list has an assortment of dryer vents for virtually any type of ductwork, but it’s up to you which one works best with your ductwork.
