K&N kills my MAFS then saves it! (heres how!)
Muahahha! I out smarted my broken MAFS 
Today I started out my day and headed out. About 5 minutes from home my car stalls, I think ohh great.. I knew right off the bat it was my stupid MAFS. I decided to keep on going about my bussiness. Now when ever the car was in Nuetral it would just stall out. So the problem is noted.. I get home and think to my self a damn MAFS allready got the best of me, I'm not letting this happen again! So reason for the MAFS failure is the fact that a after market oiled filter got oil on teh electronics, this is a given. So I wonder down to the basement wondering to my self what could safely get this oil off.. Hmm, I see my K&N recharge kit starring me in the eye, lol. I inspect the box and I look at the bottle of "air filter cleaner". Hmm, it says it removes the old oil and cleans out the filter. Well if it effectively and safely cleans the oil off of a cotton filter it might work on the fine electronics found in the MAFS.
Long story short, I removed the MAFS, then I took the actual guts of the MAFS out of the MAFS tube. I sprayed the K&N filter cleaner all over the the damn thing. I let it sit for 10 minutes. Then I rinsed the the MAFS off real good with some tap water. I then grabbed my trusty heat gun and I used it to dry the MAFS out real good. Next I installed the MAFS guts back into the tube and reinstalled the whole thing onto my car. Started the car up, car idled perfectly! Went out for a good 12 mile ride and the car seems to be 100% fixed! So to all of you who have mafs problems or for the people who will encounter them, there is now a cure! If this holds true we should add this to the facts. I will update the situation over the next few days

I think this would be a better idea.... or probably a brake cleaner?

I've been cleaning MAF's with Intake Cleaner. You don't need water with that stuff. Just spray it on and the gunk falls off. It air dries in minutes. I think thats a much better way to clean your MAF.
I clean my MAF with every air filter recharge. Never had a problem.

VW and Subaru drivers have become experts at cleaning out MAFS. Theirs are way more sensitive and delicate than ours.
Anyway, one cleaning technique that seems popular is to put the complete MAF in a plastic bag. Then put about half a cup of rubbing alcohol in the bag and swish it around until the MAF is clean.

I've been saying this for some time. This has been a common fix on many boards for the K&N. If the dealer tells you it needs replacing or you buy a new one...you are wasting money plain and simple. There is NO WAY oil will cause a MAF to die. The MAF gets coated in oil which screws up the readings which causes the computer to become 'confused'.
I would recommend using TB cleaner. What is the MAF made of anyway? I would be afraid of water or water based products corroding the MAF.

Using the heat gun got every last bit of liquid out right after I rinsed.

Re: K&N kills my MAFS then saves it! (heres how!)
Emax, my 2001 Maxima had the same problem. My cone intake I got from MAtrix was over oiled. After about 10 min of driving, my car went into a form of dieing, to not going over 4k of rpms. The car just was having problems. I removed the intake, and saw that the MAF had oil on it. I used CARB Cleaner and sprayed it on the wire really well, and air dryed it by holding it in my hand and swinging it for a little while. After reinstalling it, and cleaned the cone and reoiled correctly, the car ran great after that.

Ditto. Electronics parts cleaner, b/c the MAFS is a what?
Nice going Emax

My car is going in this week for a tranny replacement and a MAFS replacement under waranty. So much broken stuff, it's starting to get on my nerves..

I dont reccomend anyone using carb cleaner, the rubbing alcohol is a lot safer. The two elements in the MAFS are tungsten and a thin film resistor. The tungsten can handle it but the resistor can be damaged if you use too strong of a solvent (ie carb cleaner).

my maf did die with a Apexi fitler on it, it lasted 6 months though but i'm still not happy. i got another coming from a junkyard tomorrow. and yes the maf monster sleeps under my bed.

The 4th gen Maximas seem to have robust MAFS. Apparently, the Minima-ness of blown MAFS seems to be a 5th gen exclusive.

Yeah, that's about it. It goes like this;
throttle body->mid-pipe->MAFS->air filter.
There's a plug harness connected to it. When you take it out, you'll see a fine mesh screen (only on the in-coming air side), black when dirty, nice shiny gold when clean. The safest thing to use is electrical parts cleaner. You can buy that at radio shack etc. Just blast spray it all over and the stuff evaporates almost instantly. That's how I did mine. Once finished, I didn't really notice any differerence
I guess piece of mind
