Clean throttle body

[mmkkpro]

I guys, I am doing the water pump on my 1990 and figure I would clean the TB while I have it off. I am reading about DAG, but I don't see any on mine. Only thing I see are what looks like rings where the throttle plates have been closing. Enclosed is a photo. The car runs and idles good. I have not done anything yet. Thanks

Doesn?t look like any dag is present.

Might the throttle body already been serviced my Marc Haibec?
He has a procedure whereby he burnishes the blades to match the inside of the throttle body, making the DAG redundant.

Marc did mine and it was a quick turnaround
