Car A/C Cleaner – Our Top 3

Top 3-5


There are few things better than the feeling of driving your brand new car around. It works perfectly, it looks stunning, and everything is perfectly clean. Unfortunately, keeping it this way can take a lot of time and work, especially if you can’t afford regular professional thorough detailing. This means that you will have to get the job done all by yourself.

Car detailing includes a wide range of processes and techniques to restore your car’s brand-new look and maintain it. This means deep-cleaning every single inch of your vehicle, conditioning it, polishing your car’s paint, then waxing it, and a lot more. Interior cleaning can be just as demanding as polishing and coating your vehicle’s paint.

Cleaning your car’s interior means getting rid of any dirt and stains while also disinfecting the steering wheel, door panels, seats, etc. And one of the most neglected parts is your A/C, which can turn into a very big problem if left uncleaned for a very long time. It can even stop working if it’s too full of contaminants.

This is why cleaning your A/C is very important. You don’t want to inhale everything it pushes into your vehicle while cooling it down. If you have a family member with allergies, a dirty A/C can cause some serious health problems. And it can create an unpleasant environment for perfectly-healthy people as well.

The best way to avoid these situations is by regularly cleaning your A/C, especially if you use your vehicle a lot or if your A/C isn’t high-quality. There are various ways you can clean, disinfect, and get rid of any bad odors, but the best way is using a dedicated A/C cleaner.

What is an A/C Cleaner

If you’re a car enthusiast that loves detailing his car all by himself, then you already know how many types of cleaners you need to successfully restore your car’s brand new look. This includes solutions for leather, vinyl, upholstery, LCD, windows, paint, and so on. And in this package, you should always include an effective A/C cleaner as well.

A/C cleaners usually come in compressed bottles with very long tubes that can be easily inserted in the A/C and used. They come in various shapes and sizes, however, they’re also always pH-balanced. This makes them perfect for cleaning your cooling and heating system. They’re very easy to use, and if you buy a strong one, remember to use a protective mask so you won’t be affected by it. Some cleaners are also designed to be used in a ventilated environment.

You can also find A/C cleaners that spray a foam that kills most of the bacteria and cleans all the dirt. They’re just as easy to use, and they’re just as affordable. Since these cleaners usually come in smaller bottles, they usually cost around $6. And more than that, you can use one bottle to clean various well-maintained cars or clean an extremely dirty one.

There are also various other ways of cleaning your A/C, like using a high-quality brush with very long bristles. They can get the job done, but they’re more annoying to use as they tend to push the dirt into the corners. But if you’re very careful, you won’t have any issues. You can also find cleaning gel or mini-dusters that will make regular maintenance an easy job. But deep-cleaning is still a must.

Why Does Your Car’s A/C Need Cleaning

If you live in a home where you mostly use fans or window-mounted air conditioners, you probably don’t know too much about A/C systems. So let’s take a minute and talk about what exactly are they and why do they need cleaning. This is very important in keeping your car’s A/C in good shape throughout the year.

Car A/C systems work similarly as your refrigerator, except they’re specifically designed for vehicles. Basically, an A/C quickly converts gas to liquid and back again with the help of various chemicals that move the heat around. This means from inside your home to outside or from inside your car to outside. And car A/Cs are smaller but just as efficient in keeping your vehicle cool during a hot summer day.

And just how any part of your vehicle requires regular maintenance to be able to work properly, your A/C is the same. If you leave your A/C neglected for a long time, dust will slowly start to build up, and various disgusting odors will make their way inside your car. You should keep in mind that while an A/C cleaner can get rid of even the worst smells, it won’t remove the source.

Continuously taking care of your vehicle’s A/C will keep the system working smoothly, and it will also greatly extend its lifespan. And more than that, you will also be able to save a lot of money on repair and replacement costs. Replacing your whole A/C system can easily cost a few hundred dollars, even more, if you’re interested in a high-end quality one. To avoid this, all you have to do is replace the air filter and clean the unit regularly.

How To Clean Your Car’s A/C

When it comes to cleaning your car’s A/C, you should keep in mind that it’s not as easy as it sounds. This is because the small slit makes it difficult for you to easily reach the inner part of the vents. That’s where most of the dirt is gathering, and that’s where you need to keep cleaning. Otherwise, you’re only keeping the outside of the A/C shiny while the inside is full of contaminants.

Most car detailers and car enthusiasts advise on using a foam paintbrush. This is because of how elastic it can be while also being very thin and sturdy at the same time. You will easily be able to insert it much further and clean almost all hard-to-reach surfaces. But as mentioned before, these brushes also push some of the dirt to the sides or deeper down the ducts and into the filter. However, if you plan on cleaning the filter as well, it’s not an issue.

No matter what cleaning tips you find on the internet, you need to check your vehicle’s instruction manual as well. This is because the manual is basically your car’s Bible. You also have to clean your cabin’s filter, which can be a little bit difficult since they differ from vehicle to vehicle. But usually, you can find it behind the glove compartment.

It’s highly recommended to replace the air filter every 10,000 miles or at least once a year. But if you spend a lot of time off-road, you should take into consideration changing it twice a year. But if you can’t afford it, clean it and disinfect it twice a year.

How to Maintain a Clean A/C

A lot of car owners live by the rule “If it ain’t broke, don’t fix it!”, which is mostly fine until they miss all car checkups then wonder what’s wrong with their vehicle. Your car’s A/C system also needs a yearly check up, along with the rest of your vehicle. This is the simplest way of maintaining your entire vehicle, yet a lot of car owners fail to do.

Even if you haven’t noticed any problems with the way your A/C is performing, it’s still highly advantageous to have it checked every now and then. This is because the system relies on 3 important components to work smoothly, and that’s the evaporator, condenser, and compressor. And like any other car part, they can get easier and easier to malfunction.

If you buy a new vehicle, the first few years should go smoothly without any issues. But once your car passes its 5-year old mark, you need to start taking the yearly checkups more seriously.

You always need to replace or clean your car’s air filter to keep fresh air inside your car and a smooth-working A/C. And one thing you should always keep in mind is drying out the evaporator after you’ve used your A/C for some time. This is because the heat-generating defrosters and defoggers used by all cars can easily build up with time. Keeping the evaporator dry will prevent mildew and odors from making their way into your A/C system.

And if you face any difficult problems, take into consideration taking your car to a professional detailing shop.
