How to clean mass air flow sensor with alcohol

When you want to use alcohol to clean your mass airflow sensor, not every alcohol is suitable. You have to make sure you are using isopropyl alcohol, also known as rubbing alcohol. Along with rubbing alcohol, you will need the following things to clean the sensor.

  • Latex gloves
  • Clean towels
  • Screwdriver
  • Spray bottle

Once you have got everything lined up, let’s get going with the process step by step. It’s pretty easy to follow along.

Steps of cleaning the mass airflow sensor using rubbing alcohol

  1. The first thing to remember is that you have to keep your engine turned off to do this. Never try to clean the MAF sensor while keeping the engine on. So, park your car and disconnect the negative part of the battery so you can avoid any shock.
  2. The next thing you have to do is find the MAF sensor of your car. Most of the time, it is placed under the hood behind your air filter. But if you can’t find it, you should refer back to your car manual to see where the mass airflow sensor is placed.
  3. Now, what you have to do is remove your mass airflow sensor from your car. To do that, you have to disconnect all the connections, including the air intake tubing, electric connections, and clamps. Then you can remove the sensor from the intake duct of your car.
  4. After removing your sensor, you will need to get to the cleaning part of it. First of all, get a plastic bag and pour some rubbing alcohol into it. Then, put the sensor inside the plastic bag and shake it properly to clean the sensor thoroughly with less effort.

While you do all that, make sure you are wearing the gloves. Otherwise, the alcohol may affect your hands.

You can also try using a spray bottle if you don’t want to do the plastic bag method. To use a spray bottle, you put the alcohol inside the spray bottle. Then you can spray the alcohol gently on the sensor to clean it.

When you opt for this method, you have to cover all the hot wires and plates not to damage them. Also, you have to make sure you’re not touching the wires because they can be very fragile to rough touch.

  1. All there is left to do is to dry the sensor. You have to give it an hour to dry or, if possible, give it a little more time. If you have used the plastic bag method, make sure to use a clean towel to dry up the excess alcohol on the sensor and leave it on the towel.
  2. When the sensor has completely dried, you can reinstall it in your car. Recheck if there is any wet part on the sensor because you don’t want it to be wet even a little. Otherwise, it may damage the engine somehow.

And there you go, it’s that easy to clean the MAF sensor using rubbing alcohol. It doesn’t need too much effort or product. You can do it using these steps.

Now, the question is, does it work like or better than a MAF sensor cleaner? The answer is no. even though you can use it to clean; you shouldn’t make this your primary cleaner. You can use rubbing alcohol if you don’t have access to a legit MAF cleaner.

Other mass airflow sensor cleaner alternatives

What do you do when you don’t have access to rubbing alcohol, either? What can you use? Well, some things can work out for you, but they aren’t your best bet.

The following cleaning items should be your last resort for cleaning the MAF sensor of your car-

Non-residue electronic cleaners

Electronic cleaners can also be a good option to go for cleaning your MAF sensors. But you have to make sure you are using a non-residue electronic cleaner. Because of that way, it has almost the same functionality and application as a MAF sensor cleaner.

The using method of electronic cleaners is pretty much the same as using the rubbing alcohol method. You do the similar things you learned above, but you are using electronic cleaners instead of alcohol.

Even though they are great for cleaning the sensors, you should still use MAF sensor cleaner if you have access. And go for these only when you can’t find any MAF sensor cleaner. One of the best options for you would be the CRC QD cleaner that dries up very quickly.

Using WD-40

Now, I wouldn’t recommend doing this, but if you are out of all the options, you can try this out. And if you do, so you have to be very careful of some things.

While the WD-40 is capable of cleaning your MAF sensor, it tends to leave some deposits. The deposits usually have the solvents you find in a WD-40 so that they can leave a coating on the hot wires. Later on, this coating completely messes up the airflow of the sensor that will lead to misinformation.

So, it’s best not to use WD-40 but even if you do so, make sure to get rid of any deposit possible. Having even the slightest deposits can cause major issues for you.

Aside from these two cleaners, you can try different MAF cleaners rather than CRC ones. Here are some top MAF cleaner alternatives you can try out-

Gunk MAS6 MAF cleaner

Using this MAF cleaner can help you make your MAF sensor much better in performance. You can see an improvement in the fuel economy of your car. It has the active effect that can get rid of most dirt, flux, and grease from the sensors.

Johnsen’s MAF sensor cleaner

If you are concerned about the safety of using a MAF sensor cleaner, then you should go for this. It’s very safe to use and has an effective impact on the sensor after cleaning as well. You can see a significant change in the performance of your engine once you use this cleaner.

Archoil MAF sensor cleaner

The best part about this sensor cleaner is its rapid working power. You don’t need to wait for too long to see the effects of this cleaner. It gets the job done within moments and has a great effect. However, it’s a bit pricey for all these reasons.

These are some alternatives to the traditional CRC MAF cleaners, which are the most popular ones. So, if you don’t have access to that, you can try these out as they are still a good option to go for.

Wrap up

All in all, mass airflow sensor cleaner alternatives are there for you, but they aren’t the best choice. The first thing to do is, look for a MAF sensor around you. If you can’t find it anywhere, you should opt for the alternatives.

Now, when you go for the alternatives, make sure to go through them by sequence. As an alternative, isopropyl alcohol or rubbing alcohol works the best in most scenarios. And they are pretty easily available as well.

If you can’t seem to find any, then you should opt for non-residue quick-drying electronic cleaners. They can also seal the deal for you. But I highly recommend not using anything other than these two, especially not a brake or a carb cleaner.
