I didn't know that it cleaned the brain. I know that when you yawn, you take in a lot of air.

You reoxygenate your blood which goes to your brain when you are tired or bored with yawning.

I would not say it cleans the brain but it does tend to wake you up a little so it may in essence clear away some of the cobwebs!

It causes you to take in a deep breath to give needed oxygen to the brain.

For the same reason that yawing during an aircraft flight clears your ears. something to do with inhaling oxygen.
