How to safely clean a throttle body?

What's the second best way to clean the throttle body ( butterfly) when it's still attached to the intake?. When I did my spacers I noticed it was pretty dirty on both sides.

I have read in a few places you want to avoid opening the butterfly with your fingers/tool and spraying with a cleaner. Some say it will damage the TB. However I have used that technique once to clean my TB while it was attached with no issues. I think I used carb cleaner. If I had to do it again I would just remove the TB bolts and clean the TB over some cardboard.

What I did was I literally took the throttle body of the engine, as in I unbolted it and held it over some cardboard, used a toothbrush and throttle body cleaner and cleaned it. I moved the butterfly valve and sprayed EVERYTHING except for the electrical connections. I literally held it open with my fingers and sprayed and cleaned it some more. It was the easiest way to do it, and sprayed my maf with maf cleaner too.

I had no problems, and wasn't aware of others having problems. You're experience may vary, but it was the easiest and most efficient way to do it AND it have me room to reach in to the engine and wipe away some of the carbon buildup (which now that I think about was not a good idea).

There's a spray cleaner at your local car parts store, but others on this forum will say to just leave it alone...and certainly NOT to touch it with your fingers, otherwise you'll need to bring it to the dealer to get it reprogrammed.

Not something I would do but

Put the key in the ignition and turn it to ON (not start), put the car in gear (D) and have someone floor the gas pedal so the buterfly opens, take a rag (maby damp with some cleaner) and carefully clean the sides.... avoid the butterfly.

Regards

Yeah, anyways... I'm not going to bother. When I reinstalled the CAI, no longer have to look at the throttle body, so all good!.

No. Simply No.

My way really isn't that bad. If you disconnect and remove the throttle body from the Engine I can't see why it give you trouble if it's cleaned and the butterfly valve is scrubbed.

I guess it's time to talk to some of the other branches and see if they can help me. I hear the fireside girls have a pretty tough unit that has a focus on search and rescue of small mamals."
