Cleaning out my GROSS throttle body (pic within).
What is the best sensor-safe cleaning product to use to clean this much filth out of my throttle body?
I've never seen one as bad as this :o

Remove the MAF sensor and IAC before cleaning. You'll want to get the passage for the IAC cleaned up anyway. I've had good luck with the Valvoline throttle body cleaner. Clean it up following this procedure from Techinfo.

For gunk that heavy, I'd use gasoline. But do follow that guide Archon linked you to. Pay VERY good attention to the IAC and the IAC passage in the throttle body. You'll notice a much smoother idle when you get it put back together.

I have used Barrymans B-12 chemtool for years. I just cleaned my TB last month. there are 3 sensors to remove. I used the Barrymans and a tooth bruch to scrub the insides clean then flushed it all out with more cleaner, let air dry.

Swifty, when giving that advice, it'* VERY important to make sure you get ALL of that B12 out of there. It will kill sensors.
As a rule, never use carb cleaner on a fuel-injected throttle body.

sorry will, I do believe it says on the can that it is safe for FI engines and O2 sensors. you have obviously been working on bonnies and 3800'* for a while so I will take your advice to heart. is there a better cleaner out there? I have found the b-12 chemtool will take out the most stubborn gunk and even paint,lol. I know valvoline makes a good TB cleaner as well.

I used B-12 Chemtool for years (before you were probably born). If they've reformulated it and clearly state that it'* sensor-safe, use it. I know the old stuff wasn't. It would dissolve cockroaches (don't ask me how I know that).
Whatever you use, even the sensor-safe stuff, make sure it'* COMPLETELY dry or evaporated before installing your sensors or your TB.

will, I am 32. I would have pegged you as a guy being around the age of 40, am I close? and I did specify in my original post to "let air dry" as wiping out your TB would only leave particles of lint and what not. I know to not use compressed air because it may leave a film of compressor oil inside. and the idea is to make it as contaminant free as possible.

I got all 3 sensors out of the throttle body. I'll probably be soaking it and the intake manifold in a pan of B12.
Here are some more cleanup issues:
Very filthy. What do I use to clean that up in prep for the new gaskets? I was thinking brakleen or some kind of cleaner/degreaser spray and a non-scratching fiber bristle-brush. Good idea? Bad idea?
