I searched and looked in the FQS post but could not find a how toon TB cleaning. Does one exist? If not Please giveme tips or sugestions. I'm going to be replacing my valce cover gasket and thought with 330K it's probabily time to be cleaned when I'm in there.

Any degreaser with brushes and maybe a scotch brite pad; rinse twice, brake cleaner. May need a pick for some of the carbon deposits (go easy on it).
throttle plate cleaner, old tooth brush and a rag. spray with tp cleaner, scrub with tooth brush, wipe with rag. do not use degreaser, throttle plate cleaner is what you need
^^^This^^^. Be careful what solvents you use, some are too harsh for the electrical components (assuming you leave them attached). If you're cleaning
the bare metal with all electronics removed, then go for it. Remember to oil
the butterfly shaft after cleaning, the cleaning process may remove
the lube on the bushings.

I just did mine. I removed all the electrical parts. The IAC will require cleaning also so best to remove it, you will need a replacement o-ring for it.
Anyways I used brake cleaner with a brush, it worked okay but the will be some hard crusty carbon that will require mechanical action to remove. I used a dental scalpel. Then followed with scotchbrite soaked in brake cleaner. This got it pretty darn clean. Finally I used a water based degreaser to scrub the whole thing, it removed any final dirt and then it was rinsed in running hot water. Nice and clean now

IME strong detergents like Purple Power or Simple Green (diluted) work pretty well to remove baked on carbon/sludge on metal, but never use them around any plastic, rubber, insulated wires, painted surfaces, or electrical components. Those industrial strength cleaners will damage those materials. Ask me how I know.
I've done what fjbj40 did and it came out ok. great to learn about a higher level of care though, thanks.
Exactly how do you re-lube the butterfly shaft? With what?

I'm wondering too, and what oil would last ... I've never heard of this before and just cleaned my TB

I would say 1 drop of 30w oil per side. Do one side and place tb on its side to soak in, flip and repeat.
That being said if you did not soak it in brake clean or any degreaser it should not be necessary. The bushings would or should be oilite so lube not necessary, theoretically

After cleaning a throttle body I've then sprayed the butterfly shaft with a TB cleaner to remove any traces of the other cleaning chemicals, then a few drops of a lube designed for door locks that has graphite in it and/or just a light weight turbine oil.
Point being with heavy cleaning you may remove any lube already in/on the bushing and it just takes a few seconds to put a couple of drops of something on the shaft and spring while it's in front of you.
FWIW
