I cleaned them with throttle body cleaner whilst leaving them in place. All worked well and idle revs are back to normal and I took me just five minutes as the only task was to loosen the rubber hose, slip the spray nozzle in and spray the cleaner.

That's not the best way to clean TBs. As others have pointed out (if obtusely), the gunk that you wash off the TBs is only moved to the manifold and combustion chamber. If there is enough crud on the TBs to have a big effect on performance, you could end up knocking a chunk loose that ends up in the combustion chamber, possibly scratching the walls or fouling plugs.

20000 miles in, cleaned them out. The car no longer "hunts" for the right RPM on cold start so that's a good sign. I'll take her out later today and do a bit of a run down and see how everything goes.

Didn't disconnect the TBs from the harness when cleaning. It's doable and safe, if not a slight pain in the back due to leaning over the side of the car the whole time.

Towels were filthy afterwards. Towel on the left was used to wipe off the inside edge of the manifold and then stuffed in to make sure none of the TB cleaner splashed in while I cleaned the TBs themselves.

I dont know if it's already been explained but if you remove the throttle body to do the cleaning you shouldn't have to re-calibrate as long as you don't move the butterfly in the middle. You can easily clean it thoroughly with out touching the butterfly

I didn't take before and after photos of the TBs but I don't know how you would clean it completely without moving the butterfly. Wouldn't it leave a thin line around the butter fly because you wouldn't be able to scrub under it? Even with TB cleaner I had to do a bit of rubbing in order to remove some of the residue.
