How do you clean throttle body build up of carbon on an Explorer?

I have carbon build up on my Explorer and would like to attempt to clean it myself.

Remove air intake tube, remove Mass Air Flow sensor and put in safe place. Spray inside of throttle body with carburetor cleaner while scrubbing with a toothbrush and while opening/closing throttle plate. Be careful not to spray any chemicals onto Mass Air Flow sensor.

You need to buy a can of throttle body cleaner, do not use carberator cleaner. Spray a good amount on the butterfly valve then while holding the valve open spray the rest of the can inside it tryint to spray in all directions. You can put too much in it.

Disconnect the positive battery terminal, then remove the throttle body. Spray some throttle body cleaner into the throttle body, exercising the butterfly valve. Once dry, reattach the throttle body and reconnect the battery. Run the engine at idle, then slightly revved. This allows the computer to "relearn" what idle is.

Remove the throttle body and clean it by hand with parts cleaner and a rag. If you can't remove it then you can buy foaming cleaner to do it.
