What should I do if the idling motor of Santa Fe 2.0L gasoline vehicle still doesn't idle after cleaning?

When cleaning the idle motor, the cleaning agent is hard and the oil seal inside is washed away.

There are many places to pay attention to in cleaning;

1. If possible, use special throttle cleaner and carburetor cleaner, but don't spray too hard. I followed a bottle, and the oil seal of the idle motor was washed off because it was too clean! The garage washes three cars in one bottle.

2. I took it out and washed it outdoors, so I took it home and washed it in the bathroom, which made a room smell and melted the plastic part of the leaking core, resulting in a new leaking core.
