2019 Chevrolet Equinox - worth buying throttle body cleaner?

Dealer wants to sell me thottle body cleaning

Some dealerships, chain auto shops, and some independent shops will try to sell unnecessary services. If your engine is running smooth without a CEL illuminated it is probably unnecessary and just additional profit for them.

Some years ago I got an estimate for brake work from a local (St. Louis) shop. There was a per-wheel line item for blowing dust out of the brakes with compressed air. I went somewhere else.
