A few suggestions if you dont like the oiled filters switch to an AEM dryflow filter.
Also DO NOT use any abrasive cleaner like carb cleaner or brake cleaner. If you can't find the electrical MAF cleaner from CRC. Go to any electronics store or even some supermarkets will have am Electric Contact Cleaner.
Make sure the MAF is cooled down before you use it. As if you just got out of the car the hotwire type MAFS can still be well hot and it will damage the sensor if you use the cleaner and it cools it too quickly.
