You need rags, part cleaner,and a brush. Remove the valve and spray with carb cleaner,to loosen the carbon build up.while that is soaking clean all other parts. With an air compressor spray out the carb and valve, be careful not to damage the bore.

I normally use carb cleaner to perform this task and it works rather well .One bad thing is they clog back up really quick .So i would have to say go get new .

You don't unclog EGR valves. Just replace the part. They are designed to be replaced about every five years depending on the car.
