The *correct* procedure is to spray, scrub and wipe until clean. If any
franchised Honda dealer does a spritz-only, he should be shot. I would
expect a spray-only to be done by AutoZone or Firestone. Or Canadian
Tire, for that matter. Just that was done to me this past summer when I
had Canadian Tire perform a Motorvac service (which includes a throtte
body clean).

ONE:
There is only one reason for sludge in the throttle body: Oil.
There is only one source for oil in the intake pipe: The crankcase
breather.
There is only one way oil can get far enough through the breather to end
up in the intake: It can't drain out of the valve cove baffles fast
enough.
There is only one reason it can't drain: Sludge.
There is only one reason for sludge: Insufficient oil changes.

TWO:
As I said before, I have seen it where there was a defect in the
throttle body or the throttle cable/linkage that caused the gas pedal to
stick, and in those cases Honda eventually issues a TSB on it.

THREE:
There have also been issues with other cars where the valve cover
baffles or PCV system are somehow poorly designed or assembled, leading
to poor drainage and oil in the intake. In those cases as well, the
automaker issues fixes for that. The fix may not be a TSB, but a mention
in the automaker's internal information documents. Honda's is
ServiceNews.

The above two paragrpahs are why I told the OP to have that checked out.
In any case, those issues should be readily discerned during a quick
investigation by a competent tech.

The fact that the OP's problem was fixed after the dealer cleaned the
throttle body is strongly suggestive of oil in the throttle body. The OP
also covers only 9K miles per year. We don't know what kind of driving
he does, or how often the oil gets changed. No one has any information
on the state of the engine's top end, or on the PCV system. Those things
matter a great deal.
