And while getting to grips with a dirty vent will maximize home safety, it’s important for another reason, too. If the vent is filled with grot, your dryer won’t work as well as it should and that’s a waste of energy as well as your time.

Can I clean a dryer vent myself?
In case you were wondering whether you can do this job without professional help, the answer is a definite yes. The only caveat is that you’ll need to be able to move the dryer away from the wall, so you might want to get someone to help you with this part of the process, and with putting it back in place when you’re done. Follow these steps.
1. Disconnect the dryer to clean the vent
Before you get cleaning, unplug the dryer from the wall socket. If yours is a gas dryer, you’ll also need to turn the supply off at the valve.
Next, move the dryer away from the wall so you can access the rear. With a gas dryer, be cautious that you don’t disturb the supply. Disconnect the duct on the back of the dryer.
2. Clean the dryer exhaust vent
The vent on the back of the dryer is a prime spot for lint to accumulate. You could go straight in with the hose and crevice tool of your vacuum cleaner, but we’d recommend investing in a special dryer vent cleaning brush, which will allow you to loosen the lint before you vacuum it up.
3. Clean the dryer vent duct
The dryer vent duct also needs to be cleared of lint. To clean it, disconnect the duct from the wall if possible for maximum access. Remove any accumulation of lint by hand, then it’s the vacuum you need once again to clean the inside. Be careful not to damage the vent duct as you work. Make sure, too, that the ductwork meets local building codes; you may need to replace it for this reason.
4. Clean the dryer vent pipe
This is where your flexible dryer vent cleaning brush comes in useful again. For effective lint removal rotate the brush as well as moving it backwards and forwards. Vacuum up the lint.
5. Clean the dryer vent in the wall
Once you’ve cleaned inside, you’ll need to deal with the exterior vent. Check first that the vent is not obstructed by anything, and remove if necessary.
To get rid of the accumulated lint take off the exterior vent cover. Loosen the lint inside the duct first with the flexible brush, then vacuum up the grot. Replace the exterior vent cover.
6. Clean up at the back of the dryer
For a thorough job, vacuum up any lint in your laundry area which might have accumulated behind or under the dryer and on the back of the machine so it can’t be pulled into the machine.
7. Replace the dryer and reconnect
When the lint’s removed, put the ductwork back in place. Push the dryer back into position, and plug it back into the socket. Turn the gas valve back on if required.
Run a dryer cycle for 15 minutes on the fluff or air only setting to check it’s working correctly.
How often should a dryer vent be cleaned?
So now you know what to do, but how often should you be cleaning your dryer vent? Well, you need to count on doing the job at least once a year. But bear in mind that in a big household where you have lots of laundry, more frequent cleaning will likely be necessary.
Telltale signs that your dryer vent is clogged
We’ve said that this is at least an annual household task, but sometimes cleaning the dryer vent becomes an urgent rather than routine job. Wondering how you’ll know if the dryer vent is clogged? Tell-tale signs include having to do extra cycles to get a load dry when it used to take just one.
Other issues to watch out for are the dryer itself becoming hotter or, worse, a burning smell. If any of these problems come up, disconnect the dryer as above, and check and clean the vent as necessary.
Can you prevent a dryer vent from becoming clogged?
The short answer is no, but you can certainly take steps to prevent build-up of lint and debris. You should remove the machine’s lint filter and clean it out after every cycle. Check the manufacturer’s instruction book if you need to find out how to do this. Remember that this task is another way to help protect your home from fire – lint is flammable and could equally contribute to a fire caused by something else in your home.
You should also clean the housing for the lint filter regularly, too. Use your vacuum cleaner hose and crevice tool.
