car: Throttle Body clean

My antique gem started having an accelerator sticking problem lately. I have been ignoring for weeks now and the recent Toyota's recall related to accelerator pedal sticking pushed me to get to the bottom of this issue. Many forums mentioned that this could easily solvable by cleaning the throttle body. A typical dealer charge for throttle body clean is $125 (I paid the same amount last year, looks like the dealer did nothing or my car is determined to go for a shopping).
Here is what I did to clean the throttle body:

-Make sure your car is shut off for at least couple of hours
-Put some weight on your accelerator pedal so that it is pressed all the way down
-Remove the hose clamp on air intake using a scree driver
-Pull the air intake out
-Put some clothes under the throttle body so that any dripping will be caught on the rag
-Spray a good carburetor cleaner into the throttle body
-Let it soak for 10 min, use a tooth brush to brush off the gunk and wipe clean
-Repeat until all gunks are gone from the butterfly valve and throttle body
-Put everything back and start the engine
-You may have to press the accelerator pedal down to get it going in the beginning
-Let it run for 10-15 min. You may notice some smoke from the tail pipe, it will clear out in 5-10 min
-If you have rough idle, you can spray some clearer into the IAC valve (the square hole in the throttle body. This normally fixes the rough idle or minor problems related to odb code for IAC valve.
