How to clean a dryer.

8 steps for cleaning your dryer.

Cleaning your dryer includes three main steps: cleaning the lint trap, cleaning the drum and cleaning the vents and ducts. For this process, you'll need basic cleaning supplies like:

• Nylon brush
• Hot water
• Dish soap
• Household multi-purpose cleaner
• Towel or sponge
• Dryer cleaning brush
• Vacuum cleaner with a hose
• A screwdriver, if you need to access your vents.

Once you've gathered all of these supplies, it's time to get started with the cleaning process.

1. Clean out the lint trap.

When the lint trap is clean, it improves airflow and your dryer's performance.

How do you clean the lint trap? First, locate it. Most lint traps are located on the top of the machine or inside the door. Consult your owner's manual if you're not sure where yours is. Simply pull out the screen, and remove the collected dryer lint with your hand.

If you want to give your lint trap a more thorough deep clean, use a vacuum extension tool to suck out any lingering dirt on the interior and exterior of the trap. Pay close attention to the moisture sensor strips and make sure these are clean.

You can also scrub the screen gently with a nylon brush or toothbrush. It also helps to use a mix of hot water and liquid detergent to remove stubborn lint. Rinse with water and make sure the trap is thoroughly dry before you put it back.

2. Disconnect the power.

Before you can start cleaning the inside of your dryer, shut it off completely. This prevents your dryer from accidentally turning on while you're cleaning it.

• For electric dryers, simply unplug the dryer from the wall socket.
• For a gas dryer, close the shut-off valve and then disconnect the supply line. Remember to cap it off to prevent gas from leaking out.

3. Wipe down the inside of the dryer.

Should you clean the inside of your dryer? This isn't something you need to do frequently, but it can help in cases when you have residue buildup inside the drum. This can happen if you frequently use fabric softeners and dryer sheets.

First, take your vacuum and suck out any noticeable debris or lint in the drum. The next steps vary depending on whether you have a gas or electric dryer:

• For electric dryers, use warm soapy water to wipe down the inside of the drum.
• For gas dryers, use a microfiber cloth and a nonflammable household cleaner to wipe down the dryer drum.

In both cases, if your dryer is smelly, you can try white vinegar to eliminate odor-causing bacteria.

After you've cleaned the drum, use a wet towel or sponge to remove the soap or cleaner.

4. Access the vent duct.

The next step is cleaning out your clothes dryer's vent and ducts. These are usually located behind or above the dryer. Start by pulling the dryer away from the wall. Give yourself about a foot of room to work with.

Once the dryer is away from the wall, detach it from the vent. It might be held in place with vent clamps (in which case, you'll need a screwdriver) or vent tape. You'll be reattaching this all later, so put the parts in a safe place while you work.

5. Clean out the dryer vent.

Once everything is disconnected, it's time to clean the dryer vent. If you're wondering how to get the smell out of your dryer, this is probably the best way. Dryer smells are usually caused by mold and mildew growing on the lint trapped in the vent. Cleaning this out can help freshen things up.

A dryer cleaning brush is the perfect tool to use for this. It has an extendable handle that lets you reach up inside the vent with ease. If you don't have one, try using your vacuum's hose extender to reach up inside the vent.

First things first, though — pull out any big pieces of lint with your hands. This gives you space to insert either the brush or vacuum. Once you can get these in, start removing the remaining lint. 

6. Clean out the exterior vent.

Chances are, you won't be able to reach everything in the vent from inside your home. You should also head to where the vent exits your home and clean it from that side. You'll usually find it along your siding or roof, depending on where your laundry machines are located.

Take the covering off the external vent, then insert the dryer brush to remove the remaining lint and debris.

7. Put everything back together.

Once everything is clean, it's time to reassemble it all. Go back to the dryer and reattach the vent.

8. Run an empty cycle.

With everything washed, cleaned and emptied, it's time to run an empty load to help dry the drum. This also gives you a chance to make sure you've connected everything properly before adding wet clothes into the mix.

Let the cycle run for about 10 to 15 minutes to remove any remaining debris.

How often should you deep clean your dryer?

Certain parts of your dryer require more cleaning than others. For example, you'll want to clean out your lint trap after every load. But, you only have to deep clean the lint screen every six months or so.

Experts also recommend regularly cleaning your dryer vent and ducts once or twice a year. You can clean them more often if your owner's manual suggests it or if your dryer isn't functioning well. In fact, if your dryer is struggling with drying loads, it’s a good sign to clean your vents and ducts ASAP.

Finally, deep cleaning your dryer's drum is more of an as-needed task. To see if it needs it, run your fingers around the inside of the drum. Do you feel residue or build-up? Then it's time for a cleaning.

What happens if you don't clean your dryer?

Not cleaning your dryer puts more strain on the machine as it tries to dry your laundry. It'll have to work harder to push hot air around, which could shorten the life of the appliance. You may also notice your clothes taking forever to get dry.

More seriously, not cleaning your dryer can put your home — and life — at risk. The National Fire Protection Association found that 32% of dryer fires were caused by a failure to clean. Uncleaned lint was a major problem, as it caused 27% of fires.
