Do you need to know how often to clean your dryer’s exhaust duct? Then, you’ve come to the right place. The purpose of a dryer vent and how to clean it are the subjects of this article.

The dryer’s vent is its most important component. On the dryer’s rear, you’ll find it. The dryer vent’s primary function is to remove moisture from the air. It also gets rid of the dangerous byproducts of gas combustion, such as carbon monoxide.

If you want your dryer to work properly and last as long as possible, you should deep clean it every six months. This is because lint from your dryer might build up in the vent. Cleaning it once a year is recommended as a result. If you use your dryer frequently enough to run it more than twice a day, you should clean the exhaust vent at least once every six months. If you don’t clean and maintain your dryer vent, you run the risk of developing a variety of issues, such as a musty odor, a gas smell, a hot dryer, and more.


Why Clean Your Dryer Exhaust?

One of the many things that we take for granted until it breaks down (usually when we have a huge load of damp towels that we need to dry promptly) is the dryer. Annual maintenance can go a long way toward keeping your dryer in good working order and increasing its longevity. Dryer machines wear out faster if they are clogged, because they have to work more.

To ensure the safety of you and your family, you should also get your dryer vent cleaned. Lint from dryers is highly combustible. The most common cause of dryer fires is a failure to remove lint from the system on a regular basis.

Indication To Cleaning The Dryer Vent

The lint that accumulates in your dryer’s vent is the most common cause of clogged dryer vents. The following telltale signs suggest that the dryer vent needs to be cleaned. The laundry will take longer to dry in the dryer than usual. As the dryer heats up, both the laundry and the dryer’s exterior are warmed. In addition, your dryer will emit either a burning or a gas-like odor. The smell can spread from the dryer into the clothes and eventually into the laundry room. When your dryer vent hasn’t been cleaned in a year, it’s likely to become clogged.

How To Clean A Dryer Vent

Step #1. Switch off the unit

Most of the time, the lint from your laundry in your dryer blocks your dryer vent. Signs that it’s time to clean the dryer vent include the following: The laundry will take longer to dry in the dryer than it normally does. The outer surface of the dryer and the laundry heat up. You’ll also notice a burning or gas-like scent from your dryer if it’s broken. There is a risk that a scent from the dryer will spread to the garments and laundry area. A clogged dryer vent is more likely to occur when it has not been cleaned in a year.

Step #2. Locate the dryer vent

It is common for the dryer vent to have a diameter of four inches and come in a range of lengths. Dryer ducts can be rigid or flexible, as well. According to the distance between the wall and the dryer, you can choose a model that fits your needs. The dryer’s exhaust vent goes all the way to the ceiling and beyond. An exhaust hood is the part of the dryer vent that extends outside the wall. So, you’ve managed to locate the dryer’s vent and the range hood. From the hood of the exhaust, take a look inside. Dust, dirt, and even tiny animals have been known to sneak their way into the dryer’s exhaust system. The stench of a dryer might also be caused by a dead animal in the dryer vent.

Step #3. Withdraw the vent

You’ll have to take the vent out of the wall now. To begin, remove any tape or fasteners that connect your dryer vent pipe to the exhaust system…. Gently extract the vent from your laundry room after that. When removing the dryer vent, take extra care not to damage it.

Step #4. Use a vacuum to clean the vent

You can use a vacuum line attachment to remove lint, dirt, and other debris from the dryer vent after you have access to the pipe’s open end. A large dead animal, such a mouse, may need to be removed from the hose before vacuuming. When cleaning the ducting, don’t forget the exterior. If you don’t have a vacuum, use a brush and a microfiber cloth to remove the dirt.

Step #5. Use of brush

You’ll have to clean the vent again to remove all the lint and debris. Using a stiff brush from the vent cleaning kit, follow up with vacuuming. You may get this kit at any hardware store in your neighborhood. Connect the power drill to the brush. To use a power drill, you can either find one in a toolbox at home or buy one. Then, gently insert the brush’s end into the vent. Deepen the vent with the brush. However, depending of the path and the connection, you may need to carefully push the cleaning brush into the dryer vent.

Step #6. Push the vent back into the exhaust hood

The dirt and debris will fall to the floor when you clean the vent. As a result, take some mops and a dustpan and get to work mopping the floor. You can clean using a vacuum if you have one. Replace the dryer exhaust hose after it has been cleaned. Make sure you use tapes and clamps to secure it in place. If you come across a dead animal, we recommend that you use wire mesh to seal the exhaust hood. If necessary, you can also utilize mouse traps.

Step #7. Switch on the dryer

Run the dryer for a few minutes to see how much air is coming out of it. Knowing why my washing machine smells and how to prevent and clean it is a good idea.

DIY Dryer Cleaning

For example, you should frequently clean and maintain the drum and filter of your dryer. In between expert dryer maintenance sessions, it’s important to perform routine maintenance on these sections of your appliance. Tips on how to clean your dryer at home are provided below.


Every time you use your dryer, make sure you clean the filter. A little door on top of or just inside the dryer normally provides access to this filter. It’s as simple as putting on your clothes, pulling out the filter, and removing the lint that accumulates over time. After a couple of uses, you should wash your filter to ensure maximum performance. Fabric softeners and dryer sheets might clog the filter’s mesh, reducing its efficiency.

To discover if your filter needs to be cleaned, remove any excess lint and test the mesh screen with a tiny amount of water. If water is accumulating instead of draining, it’s time for a wash. The mesh should be cleaned with warm, soapy water and a brush or sponge until water can flow freely through it.


The portion of your dryer into which the clothes are placed is known as the drum. To keep the drum clean, you should wipe it down on a regular basis to avoid the accumulation of muck or other debris. This is especially true if you have a lot of pets or young children in your home that wear dirty play clothing while playing. Use a moist cloth to wipe out the dryer’s drum if you find pet dander or grit within.

Is there anything that can be done if there is a spare stick of gum or lipstick in the drum? There is no need to worry if you find residue left after your garments have been removed. Allow the dryer to warm up for a few minutes to get rid of any lint that may have accumulated in the drum (maybe with some towels or rags inside). The residue can be scraped off the inside of the drum with a towel or even a hard spatula. You can also use a damp cloth, a small quantity of laundry detergent, and some hot water to get rid of any remaining residue.
