The recommended frequency for car detailing depends on how you use your vehicle and the conditions it faces. For most cars, a full detailing every 4-6 months is ideal to maintain the vehicle’s appearance and protect it from wear. If your car is exposed to harsh conditions like frequent sun, road salt, or dirt, more frequent detailing (every 3-4 months) can help keep the paint and interior in good shape. Regular interior cleaning is also suggested to keep the upholstery, carpets, and other surfaces looking fresh.
