What's the difference between carburetor cleaner and mass air flow cleaner?


Yes, both carburetor cleaner and mass air flow cleaner are made to clean away built-up crud, but it's the chemical compositions that really apart these two cleaners.

Carburetor cleaner is specifically designed to work on metallic surfaces more commonly found in older cars, while mass air flow cleaner is formulated to not break down the plastics found under the hood of more modern cars.

I like it! Was kind of expecting to hear something about some cleaners leaving a residue that would change the thermal mass of the tiny heated wire in some MAFs and thus throw off its airflow reading? Urban legend?

In reply to Vigo (Forum Supporter) :

The oil residue that the MAF cleaner cleans up does change the sensor. Seen that happen with an oil impregnates air cleaner test car.

Bought a can of the CRC mass airflow sensor cleaner last week. Never used it before. Are there some cars that should not have this used on them?
