The direct answer
Clean the inside when its use and condition call for it. A car used by one careful adult may need only quick upkeep for months. A family van, pet car, work truck, or rideshare vehicle may need attention every week.
Use the mess, not a rigid calendar
Remove food, wet items, and spills soon. Vacuum when grit builds in carpet or seat seams. Wipe touch points when they feel dirty. Clean glass when haze affects your view.
Children, pets, frequent meals, dusty work, outdoor parking, and daily passengers can shorten the time between cleanings. There is no single correct schedule.
Try a 10–20 minute reset when needed, a fuller home clean every few months, and a deep service only when ordinary cleaning no longer solves the problem.

When is a paid detail worth it?
Paying makes sense when the job needs more time or equipment than you want to buy. A lightly used cabin may need only a cheaper maintenance service.
