What are the benefits of cleaning car speakers?

how to clean car speakers

There are many benefits to keeping your car speakers clean.

  • Firstly, if you have a clean car, your journeys will become more fun and adventurous as cleanliness brings peace and comfort.
  • Secondly, clean speakers will last long, and the audio quality will remain the same as when the speakers were new. 
  • Most importantly, you will not need to change your speakers very often as there will be fewer chances of the speakers getting damaged. 

What will you need to clean car speakers?

You don’t need to buy new equipment to clean your car’s speakers as you can use the equipment you have at home. There are several things which you will need while cleaning your car speakers. These things are as follows. 

  • Microfiber cloth 
  • Small soft cleaning brush 
  • Lint roller 
  • Water spray 
  • Air spray can
  • Small vacuum cleaner, 
  • Sonax rubber protectant

If you have any of these at home, cleaning speakers will become straightforward. On the other hand, you do not have to spend a fortune on good quality cloth or brush if you do not have one.

How to clean the speaker cone?

Start cleaning the woofer by blowing it with compressed air that should remove all sticking dust particles. To clean the woofer cone, use a wet microfiber cloth and wipe it down slowly across the edges until it’s spotless. Use the other dry microfiber cloth to remove the remaining moist in the woofer cones, and make sure to dry the cone after cleaning.

Don’t use anything other than microfiber because some cones are so delicate that even a small scratch can damage the speaker.

How to clean plastic speaker cones?

Plastic cones can handle more pressure compared to other parts of a speaker. Any stain or dirt stuck to the plastic can be treated with a stain remover lotion using a microfibre cloth and then allowed to dry. 

Sometimes you might get random stickers from quality checks on the plastic portion of the speakers. Don’t use your nails or any metal objects to remove them. Instead, you can use nail polish remover to gently peel the stickers off the plastic.

How to clean subwoofers?

When it comes to the subwoofers, you do not have to be so sensitive with choosing the softest microfiber cloth, and you can use more heavy-duty equipment. 

I am starting to clean my subwoofers with an OPOLAR vacuum cleaner, making this process easy and quick. This way is best for cleaning the dirt on the woofer cones’ surface, especially those not often used.

The most important part of the vacuuming speakers is to use a relatively soft sucking brush to prevent any cone damages and not too intense sucking pressure, so if your vacuum cleaner at home has both, use it.

How to clean the rubber surround?

If you look at the edges of the cone, you will find surrounding made of foam, or in higher quality speakers, made of thin butyl rubber. To clean them, follow the same principle of cleaning with the microfiber cloth and when finished, use the Sonax Rubber Protectant over the area and wipe it dry.

Sonax will give additional protection to the rubber and will make it more elastic, increasing the lifetime of the speaker.

How to clean tweeters?

This is the most common question that gets asked a lot on how to clean tweeters, but actually, it is quite simple. Use the can blower to dust off any sticking dust particles.

Remember however, do not ever touch the tweeters. Do not use the microfiber cloth or make tweeters wet because it will do more harm than good. 

How to clean plastic or metal speaker grills?

Speaker grills are designed to protect the speakers, and often they get dirty first. So, how can we clean metal or plastic speaker grills?

Cleaning grills is the least difficult part of the whole process because they do not produce any sound and can be simply removed and cleaned with water and soap. 

You can use a soft brush to scrub dusty corners, but do not forget to use a dry cloth and dry them before mounting back after cleaning.

How to clean grills that cannot be removed?

In some cars, it is difficult to remove the grills, and in this case, it becomes tough to clean the car speakers properly but don’t worry. In the case mentioned above, you can use a lint roller or compressed air to clean your grills, which can’t be removed.

When grills are covered with fabric, cleaning this becomes the most difficult, but you can do it with water and soap. If you have a small vacuum cleaner, you can use it first, but a vacuum will only clean the dust, and you will need to clean the dirt with a cloth or a soft brush.

How to get stains out of the speakers?

You have to be very careful when you are cleaning speakers that have any liquid stains. There are so many delicate parts in the speaker that you might end up damaging one of them.

Depending on which part of the speaker was spilled on, you have to use different ways to clean them. 

When it comes to tweeters, cleaning is straightforward. Simply clean the cone with a soft microfiber moist cloth and allow it to dry but don’t apply too much pressure while cleaning the spilled liquid.

If you spilled liquids onto a sub-woofer, cleaning could be tricky, especially when the subwoofer has a paper cone or foam edges. The most efficient way to clean the speakers without damaging them is by allowing them to dry first. If there is a stain, remove it using a window cleaner and a microfiber cloth.

How to remove rust from speakers?

Sometimes you notice that you are not getting any sound from the speakers, although everything seems to be working fine. After investigation, you find that your wires or speaker terminals are corroded. This is a common scenario, especially in the door speakers that do not have proper water protection. 

The best way to get rid of the rust from the speaker terminals and wires is to use a thin brass brush. While using a brush, you need to be careful because, in some cases, damaged terminals can separate from the speakers. 

If that is the case and your terminals become loose, you may need to replace them with the new ones after cleaning the whole area. 

But let’s go back to the cleaning. When all rust has been removed, next you have to clean all connection areas with Deoxit D5. You can leave a little on the connections to help prevent future corrosion.

After cleaning, you can spray the whole back of the speaker with NANOPROTECH Automotive Invisible Coating Water Protection Fluid Film that will keep the entire surface from further rust or oxidation.

How to not damage speakers while cleaning?

  • Don’t use rags or any clothes other than microfiber.
  • When it comes to the tweeter, don’t touch it even with a cloth.
  • Ensure that you don’t cause any scratches as well.
  • Don’t use any other liquid other than water on the subwoofers, especially these with paper cones. You might end up damaging them.
  • Always apply minimal pressure possible on the elastic parts of the speakers.
  • Don’t use brushes when cleaning any part of your speakers. This may cause scratches and damage to soft tweeters.
  • Don’t use alcohol or any other stain removers on the speaker, unless for cleaning the grill, basket, or magnet.


Cleaning and taking care of a car’s interior is an essential part of having a pleasant journey when you are traveling somewhere. You don’t want to have an annoying sound from the speakers just because you left them uncleaned.

Leaving your speakers with dust and stains will lower their longevity and can affect efficiency over time.

Clean your speakers using a microfiber cloth once a week and check for any stuck dust particles.

Taking regular care of your speakers ensures the lifetime and the quality of sound to be excellent.
