EGR Valve Cleaning

Does anyone have a how to or even some pics on cleaning the EGR and what to use? I am going to clean it with throttle body cleaner. Anyone got any other advice for me? I also purchased a TomCo gasket with the metal mesh screen to replace when I take it off. Thanks guys and gals

The main thing is to look for a carbon ball under the seat.
Just spray it a few times but do not push in on the plungers on the electronic valve.
What is it doing or not doing?
Got any codes?
