Guarantee that isn’t smashed behind the dryer. Expecting it can’t avoid being, it could cause restricted breeze current.

So what is this gadget? This gadget is related to a cordless drill, and it is installed into the dryer channel. Since you’ll hear and feel an accident when the dryer vent cleaning instrument shows up on the rooftop, you’ll know when it’s done. The dryer vent cleaning is striking the roof cover, which causes the unexpected stop.

  1. Move bit by bit up the vent with the dryer vent cleaning mechanical assembly
  2. Brush the sides of the dryer vent to loosen up the development.
  3. Endeavor and go up past what many would think about conceivable with the help of the contraption.
  4. Go all over different times to clean your dryer vent from the inside.

3. Clean lint from the vent

When you clean the dryer vent from the inside, all the lint falls to the bottom if you have a vent that goes to the ceiling. Your dryer vent plays a very crucial role in your home. It allows the air in your dryer to circulate properly. You will notice that the heated and polluted air within the dryer will leave smoothly. Dryer vents thus get dirty very easily. The lints must be removed before the dryer can be used efficiently. To help with this, you must use a dryer vent cleaning tool.


The development should have gotten together at the lower part of the channel when you dispose of the dryer vent cleaning instrument from the vent. You should have the choice to reach in and wipe out the development with your hand, which might be a couple of unassuming packs.

Following the development removal, I recommend continuing with the tidying and developing clearing movement until no more development tumbles down.

4. Access the roof to clean the vent

It anticipates that you should genuinely get on the housetop to clean the dryer vent. Benevolently don’t try this accepting your roof is particularly steep, and tall, then again if you feel very off-kilter bouncing on the roof. Find a confirmed roofer who can work safely on the roof. To get to the roof safely, you ought to consent to the prosperity wellbeing measures and rules while rising a ladder.

Attempt to have genuine gloves and shoes, and attempt to have a ladder security harness to hold yourself back from hurting yourself if you fall. That being said, when you are on your roof, you can keep on cleaning the housetop in front of any trash and guarantee the flapper is working suitably.


Upon getting to the top of the house, insert the dryer vent cleaning mechanical assembly, and make sure to reach the upper section of the dryer vent. Damage should go down the vent after you hit or scratch it. If you hit it, it will begin to die.

5. Verify airflow using the leaf blower

In this solution, you can verify whether your vents are clogged by using a leaf blower to blow inside the vent. By examining whether the airflow is weak or missing, you can decide whether your dryer vent is clogged or not. This can also be done with the help of a leaf blower. Also, the duct in the attic may be disconnected, which is easy to check by looking in the attic.


To clean a dryer vent, start by detecting where the dryer in your house is placed. In your case, it might be placed on the rooftop. Once you have recognized your dryer exhaust vent, take a look inside for any blockages caused by a build-up of lint. If there are any build-ups, disconnect the dryer from the power source and remove any metal clamps or tapes with the help of screwdrivers.

With the help of a vacuum, clean the vent of lint or other specks of dirt. If required, attach your vent cleaning kit with a brush and push the brush as far back up as possible. This will cause any lints to fall, cleaning your dryer vent.

6. Using a brush to clean the dryer vent

In this step, you can use a brush to help you clean your dryer vent. Cleaning the dryer vent using a wire brush might be difficult. It can, however, give you the immediate benefits of a clean vent. Some of the brushes even come with drill attachments so that you don’t have to struggle to get the brush all the way through the vent. There are two advantages to using a wire brush with extension rods.

They are simple to use and can pull the lint out quite simply and efficiently. The wire brush’s sole disadvantage, when used with extensions, is that they might become trapped. Fortunately, if you use common sense and avoid pushing the brush and extensions into the vent, you should have a lot of success.


First, you will need to find out where the dryer vent is in order to clean it. It is highly likely to be placed on your rooftop. So, after you have successfully recognized where your dryer exhaust vent goes, you will need to examine the blockages and build-ups caused by lints and other dirt. If you detect any sort of build-ups, you will need to power down your dryer.

Then start by removing the clamps of metal and tapes using your handy screwdriver. Using a brush stuck to a dryer vent cleaning kit, pull out all the lint you can get your hands on. Simultaneously, keep pushing the brush as far up to take out more lint. Doing so will cause any lint stuck to the vent to fall out.

7. Cleaning the dryer vent cap

Your dryer vent has a cap for many different reasons. The cap protects the vent from birds, pests, rain, and blowing debris or dirt. The cap also restricts the build-up of lint within your dryer vent, making it easier to clean. Like lint and dust on the inside of the house, lint and dust will build up around the house’s perimeter at the dryer vent cap. Excess lint build-up can sometimes be so serious that an entire vent can become clogged. It will not be a surprise if your garments are still moist after many drying cycles in this situation.


To clean the vent cap, remove it from the outside of the home and vacuum the area around it until it is clean. Take the cap and pluck out any hair or lint that might have caused the lint build-up. This is especially true in a household with a lot of girls when long hair gets into the laundry and is blasted out the dryer vent.

Check the vent cap to determine whether it needs to be changed once all the undesired items have been removed from the surrounding region. Dryer vent caps are your first line of defense against birds and rats making a home in your dryer vent. It’s time to replace the vent cover now that everything is working properly.
