Frog, some people's MAF's (including the one on my car) ABSOLUTELY NEED a good scrubbing (I used Q-tips but would like to go back with pipe cleaners to get the back sides of the wires a little better).
The analogy with the car wash is dead on. By scrubbing you can remove more than you can by just spraying. That should make sense to you.
The previous owner of my car drove it around on rugged dirt roads around his house for about 95K miles of it's life. I can tell you 100% without a doubt that I would have never gotten all the baked on dust and crap off of the MAF wires if I had not physically scrubbed on them. I have tried cleaning the MAF sensor many many times with just the spray, and every time using the spray only, I could still see discoloration on the wires after I was done. After finally scrubbing them they look new and the car performs sooo much better that even my wife was like "wow, the contour is so much more fun to drive now!"
I just wanted to make sure other people reading this thread aren't misinformed by your lack of experience in this specific area.
You shouldn't say something isn't necessary just because it hasn't been necessary in YOUR OWN EXPERIENCE.
