If they now have these special coatings, why does the stealership still want to clean it? I doubt they would use a special cleaner that wouldn't ruin the coating.Shouldn't need to be cleaned and isn't recommended - most throttle bodies nowadays have a coating on the throttle plate to prevent buildup. If you use solvent based cleaners on them, you will ruin the coating.
They want your money and likely all they would really do is pull off the intake, look inside and say "yup it's clean". Most people wouldn't even notice a difference due to the ECM making constant adjustments to compensate for a contaminated throttle plate/bore.If they now have these special coatings, why does the stealership still want to clean it?

That stuff is no different than regular old carb cleaner. I still wouldn't use it on a Tundra TB unless it's absolutely necessary. Our engine uses silicone intake o-ring seals and those solvents will soften them, so if you do use that stuff I'd recommend doing so sparingly.Genuine Toyota Throttle Plate Cleaner, part# 00289-1TP00.

I'm not aware of any over-the-counter carb or throttle body cleaner that has the same mix of ingredients as the Toyota brand. Example: the can of Gumout Carb cleaner I have says it contains: acetone, xylene, methyl-ethyl ketone, petroleum distillates and propane, vs the Toyota brand contains: acetone, methanol, petroleum distillates and toluene.That stuff is no different than regular old carb cleaner.
