just cleaned my throttle body today for my 6gen accord
You will need:
-Screw driver
-1 can of Sea Foam
-a Can
-a baseter tube or funnle tube
-a straw (from a sports bottle)

This is the engine bay

Your throttle body is connected to your intake
you want to remove it by using your screw driver, then you will stick the straw into the throttle body plate inside
It should look like that with the intake removed

you can stick the tube in to the TB
