A careful hand wash every two weeks keeps dust from grinding into the paint. A full interior and exterior detail a few times a year is enough for most daily drivers. A coated vehicle still needs those washes. The coating makes them easier. It does not cancel them.
Paint correction is not a monthly service. It is for when the finish looks tired in the sun. Doing it too often removes clear coat you cannot get back. Maintenance visits are for vehicles that are already in good shape.
If kids, dogs, or a long commute fill the cabin faster, book the interior on its own instead of waiting for a full day.
