It's an eletrical contact cleaner. I don't know if it's any different than other electrical cleaners but I figured the safest (and easiest) bet would just be to go with the CRC branded MAF cleaner that they sell at AutoZone. I'm sure they sell a MAF cleaner at all other auto part stores as well.
You just disconnect the MAF sensors from their connectors, then unscrew them from the MAF tube. Pull them out very carefully, holding at the base, and spray them per the instructions on the can (about 15 good sprays). Let it dry (it dries in seconds), and reinstall. Be careful not to touch the sensors with anything... they are very easily damaged.
If your sensors are dirty the ECU won't receive accurate or reliable air flow readings which can negatively impact engine performance.
While you're at it, clean your filter and airbox of dirt and debris. If a leaf or other debris makes it's way into the airbox it's possible that it could block a good portion of the filter, which can make a big impact in performance.
