Spray and let dry. DO NOT touch the maf elements with ANYTHING.

Delicate parts don't like contact or residue.

The only brake cleaner that is worth spending money on for any work is the 3M stuff. Doesn't leave a residue, and it actually cleans parts, an added bonus is that its flammable so you can run a rig in the shop on it when you are moving one around with a bad fuel pump.

The manufacturers will tell you dont clean them at all. I have personally cleaned hundreds with many brands of brake clean and they all seem to work great. The great part about brake clean is that it leaves no residue
