Mass Airflow Sensor cleaning

I heard from a source that shall remain nameless that you can clean a mass airflow sensor with brake cleaner. Is this true, or will I be hosing an expensive part if I try it?
I was told that cleaning the sensor will help the car's computer get a more accurate reading of the airflow and cut down on knock/ping.

not brake cleaner. that might just melt any plastic that is in there.. you gotta use some windex or plain rubbing alcohol.. i apply it with a Q-tip.. make sure that the cotton on the end of the Q-tip does not leave any traces of cotton on the small metal part inside the area you are trying to clean.... when i do mine i have some high power head mounted maginfiers so i can see what i am doing.. the part that has to be clean is very small and you dont want to break anything as a new MAF is gonna cost you $50 plus......

Yes you can. I've done mine a couple times. Just spray the residue-less brake cleaner on the wire assembly that sticks down into the air stream and let dry. Some people rub the wires with a qtip or similar but I don't touch them as I've heard they are easily damaged if you do. They look pretty sturdy though. Cleaning mine on my explorer seemed to cure a persistent pinging problem I'd been having. -- Elbridge Gerry, of Massachusetts:
