I did both of my MAFs. I had no CEL on my dash or any symptoms of dirty MAFs, I'm just anal that way, LOL. The driver side MAF was visibly dirty, the passenger side sensor looked ok but I cleaned it anyway. I used the CRC product specifically labeled as MAF CLEANER. You can NOT use carb cleaner or anything else. You also MUST disconnect the battery before unplugging and removing the MAF to ensure no CEL light after you re-install. You will need to completely remove it, then spray WITHOUT saturating the surrounding area. Just a couple of sprays is all you need. Then the sensor has to sit in a dust and dirt free area for about an hour to dry completely before you reinstall.
You might need to reprogram the auto windows, etc after you reconnect the battery too.
