Cleaning Mass Airflow Sensors

HEY!! I have a 2008 Xterra and have read lots of things saying that cleaning your MAS will help you get slightly better mileage if its actually dirty. Is there any particularly RIGHT way to do this? Can i just remove it from the intake and wipe it off with a rag? (assuming its actually dirty)

Spray with MAF cleaner. DO NOT TOUCH the filament. If you break that hairlike filament, the sensor is useless. If you don't want to spring for the spray cleaner then you can do alcohol and a q-tip but be very very careful.

i cleaned mine a couple weeks ago with the spray, (on the can it claims to get 4-10HP at the wheels hahahaha) i dont believe that, but its eas enough to do so.... actually if you go to james' post on how to get the most out of your stock intake, near the top he has a link to a vid of a guy cleaning his MAF sensor. but pretty much the process is undo the screws disconnect the wire that puls into the sensor take it out, spray the thing, i probably wouldnt touch it i think its better to spend a few bucks on the spray than to risk braking the damn thing, and its kind of encased in a plastic thing. put it all back togther. if you have a 2008 i doubt it could be that dirty, but again it wont hurt it and you could be like me and pretend that it gave you 4-10 HP haha
