best way to clean MAF ?

I was just wondering how you guys do it. I read a thread a while back where someone picked up a few rwhp on the dyno after spraying the MAF with carb cleaner. I would assume you'd run the car and spray the carb cleaner directly into the MAF allowing the vacuum to suck this cleaner through the MAF and into the intake subsequently cleaning out everything on it's way through. I was leaning towards doing this while manually reving the throttle on the TB to make sure the system is cleaned out.
Is this method recommended?

That's great.

Thanks for the reply.
