I have only used stock air filters, and cleaning my MAF at ~16,500 miles resulted in a significant improvement in smoothness and throttle response.

Now I'm at 19,000 and it feels like it could use another cleaning, I'll try the carb stuff.

I may be corrected, but carb cleaner and electronics cleaner use the same solvent "TCE" which will cut through any hydrocarbon based fouling.

Most carb cleaners contain acetone, a very aggressive solvent.

Acetone is perfectly safe for the sensor wires.

what about the plastic that the maf is housed in? will acetone affect it? I know acetone will melt some plastics. It's used as a clean up solvents for polyester.

After about 10,000 cleanings, the carb cleaner or starter fluid may begin to have an effect on the pastic. Don't worry about it. Don't over analize this simple cleaning process. Do it and be done with it.

Acetone will dissolve paint, most plastics and the protective varnish on copper wires. However it evaporates so quickly it probably doesn't have time to do harm when sprayed on.

curious, do you guys actually use acetone? Or just assuming it’s ok to use. Maybe one of you guys that say it’s Ok to actually try it and see..and let us know how it goes.

I have a strange feeling you may get away the first few times, but once the acetone starts to emulsify the plastic it will start to deteriote quickly.

Or can try it and send you a bill if the plastic starts to melt? ok?

Trichloroethene (TCE) is the active solvent in electronics cleaner. It is safe for plastics, connectors and wires. It is not safe for you as it is a know carcinogen. Circuit board manufacturers use TCE to clean the boards. Some of the electronics cleaners have a lubricant in them, get the ones that do not have it as it may foul the conductor wire and plate on the MAF. Acetone is a resin based solvent, not really so good on oil base.

Which part of the MAF needs to be cleaned? The wires? There are wires on the outside of the MAF and there appear to be wires inside as well (which I circled in yellow) as you can see from the picture below. Do they both need to be cleaned? Also there appears to be a window or film on my MAF that was somewhat dirty (under where the inner of the two arrows is in the last picture), does that need to be cleaned?

By the way, I'd also recommend an offset ratcheting screwdriver so that you don't have to remove the air filter housing, in the event that you would like to clean the MAF but do not need to replace the air filter. Also I bought a set of the torx security bits on ebay for $3.00 which work great with the offset ratcheting screwdriver.

Incidently, my MAF wasn't that dirty. The pictures were all taken before I cleaned it. I have about 19k miles on the car and I use a K&N filter, do they usually get dirtier by then?

Why not use MAF cleaner?
