Nice comparison, there is indeed a difference in the formulation, but the polystyrene cup isn't really showing anything. All the plastics used for engine components are immune to the solvent in regular carb cleaner, and it can be used just fine. Reminder that gasoline will also dissolve a polystyrene cup. Will pouring gasoline all over the plastics of your engine melt or damage them? Imagine the scandal if that would be the case.

There is even a more important difference between them and that is one is meant to leave a residue behind (Carb Cleaner) & the other not to leave a residue (MAF Cleaner) because the residue would affect the readings of the MAF working correctly.

glad i saw this, my question though is. if you leave in a place where you cant find a mass air flow cleaner, is there an alternative product that is easily available that can be used for the same purpose?

This video is the answer to some guys here in YT which spray their MAF sensor with any kind of spray you can imagine except the proper one. Thank you for the demonstration sir, best regards from Greece.

Brilliant demonstration! 👌🏼

First of all, these parts are not polystyrene, and secondly carb cleaner, or anything like it, evaporates long before it does any harm. I use electronic parts cleaner for everything. The only reason to have all these different products is if you're a CRC stock holder.

Wondering if you can use CRC electronics spray cleaner in place of CRC MAF sensor spray cleaner. both say they will not leave a residue.

Can I use MAF or THROTTLE body cleaner to diagnose vacuum leaks?

Major crc maf cleaner shortage here in KCMO. I cleaned mine with carb cleaner. Got lucky. 2 months later and seems fine

Air flow sensor cleaner is very look like to fast thinner. Is it ok if I use fast thinner instead?

For most independent contractors and even most dealer ship they use crc throttle bottle for basically every thing lol. Even use it to spray mass flow air sensor. For home user they buy different types like crc mass air flow cleaner for electronics components/ air flow sensors.

This Very good information to know. Thank you.

Can mass airflow cleaner remove oil buildup around the valve covers gasket?

Deja vu! Good explaination. Can we maybe also throw throttle body cleaner, and intake valve cleaner, in there? AKA explain ALL the various awesome CRC stuff that gets sprayed down intakes! Great presentation, just want more.

Thats Brilliant just what I wanted know.. Thanks

Can you clean the MAP sensor on an 88 Ford Thunderbird (5.0 engine)

What about electronic contact cleaner. Is it okay for cleaning maf airflow sensor ?

Maf cleaner for injectors??? good idea?

Thank you for this video!!! Good to know there is a good difference!!

what would you recommend to spray to find a vacum leak. People have told me to use carb cleaner. 2002 chevy., lots of plastic under the hood.

Can I use carb cleaner on maf or map directly in the sensor peace not the plastic if I’m on the side of the road

Welp.. Glad I watched this video. I was about to wing it and Unknownlgly melt plastic components under the hood of my car. As a gesture of my gratitude. I would like to give you a digital 👊🏿 and a 🍺. Peace

For what I believe they are different from one another but they are both cleaners, designed and engineered according to each and every car/Engines Manufacturer's Specifications and Recommendations. I've been using only just 1 brand for many years that's CRC brand. I never had any Lean or Rich fuel problems on all of my Gasoline Vehicles, I clean MAF sensors every 3 months or 4 times in a year. Sames goes to Throttle body whenever I clean or replace Air Filters I also clean the throttle body and the MAF sensors with the specific Cleaner. Sometimes they don't work because you have some other issues such as the ECM module needs to be Re-Calibrated or Re-Evaluated meaning Tuning it to give it more Fuel. Or perhaps maybe the throttle body is defective is and it is not functioning the way it is! Or maybe the Fuel Injectors are defective and needs to replace so the cleaner doesn't work no matter how many times you clean the MAF or Throttle body because the fuel injector is screwed up. Or maybe the Sparkplugs needs replacements.

Whats the alternative for maf cleaner where i live in a area without maf cleaner??

Will rubber be ok like an o-ring will it be ok with a carb cleaner?

What's an alternative to maf cleaner?

In theory, probably yes, but in reality, the carb cleaner evaporates quite fast (not like a cup) and the ABS plastic is much stronger than a foam plastic.

can I use Mass Air Flow cleaner to clean IAC?

Interesting that folks dismiss the validity of the test simply because the MAF has no styrene, or because you don't soak it. The point is that carb cleaner can or will damage the plastic found on modern MAF sensors.

You dont spray mass air meters with the engine running/ key on. If you do it can ruin the meter. After spraying let it air dry well several minutes before starting the engine, or the meter could be ruined. A few extra bucks for the right priduct is cheaper than $100 for a new sensor.

I love your energy. thanks for the explanation! about to clean my throttle body with carb cleaner and just wanted to make sure of any harmful effects.

Can you tell me the difference between "CRC QD electric cleaner" and "CRC MAF cleaner"?

Why two different colour cups for a fair test?

Is it me or does the voice representing CRC industries, at the end of the video sound EXACTLY like Jason from Engineering Explained?

Thanks for the information and excellent illustration, Grassroots! 🙂 Remember that God loves ❤ you !

However, there's a saying.. "It's better than Nothing" The metallic porpuses.. That product is sometimes very difficult to find.

I doubt if spraying down a plastic engine part with good old fashioned carb cleaner is going to do any harm. It eveporates almost instantly. If on the other hand you're a guy that likes to make deep puddles of the stuff on top of your plastic engine then this product is for you.

"MAF cleaner is designed to clean petroleum byproducts...". How would petroleum byproducts get into the MAF? Wouldn't the contaminate be dust that gets through the air filter?

Yes... But who would let their MAF sensor get soaked for few minutes? The best people do is spray and wipe... Although I agree not to use repeatedly...

Or my god, thanks for explanation

What about electric contact cleaner?

Isn't this just electrical contact cleaner basically?

greatBUT couldya just have no background percussive irritating non-music? please?

If plastic is the only limiting factor then we can just use alcohol? Cuz all alcohol is safe on all plastics. Probably a 75% alcohol and 25% distilled water is probably best

It must be very hot in that shop :D

But I'm not going to soak the component, I'm only spraying and and it will be dissipating gone. So dont soak it in a cup or container. 20$ vs. 3$

Carb cleaner can solve the plastic garbage problem.

This is beyond the dumbest test i have every seen, you are not gonna let a maf sensor sit submurged in carb cleaner, plus that cup is not by far made of the same plastics that the casing of the maf sensor is made of. I have cleaned countless maf sensors with carb cleaner with no damage to them period. Clean with carb cleaner and blow with air and it'll be fine. I am a ASE certified mechanic and have been for over 30 years and have never had any issues using carb cleaner on a maf sensor. Your test is like comparing apples to steak meat( cup plastic vs maf sensor casing)....GTFOH with that BS.

Nice magic trick. has anyone tried this themself?

Brake cleaner, my next best customer, next to alcohol .....

I use brake cleaner. No residue.

What a joke
