The frequency at which you should get your car detailed depends on several factors including how often you use your car, the conditions in which you drive, where you park, and your personal preferences. However, as a general guideline:

Basic Interior Clean:

Once every one to two weeks, especially if you frequently have passengers or eat inside the car.

Full Detailing (Interior and Exterior):

Every 4-6 months. This helps to maintain the car’s appearance and can be essential for protecting the car’s finish from contaminants and UV rays.

Exterior Waxing/Sealant Application:

At least twice a year, especially before winter and summer, to protect the paint from harsh weather conditions and UV rays.

Engine Bay Cleaning:

Once a year or as needed. It’s good to check for leaks, damaged hoses, or any other issues.

Undercarriage Cleaning:

At least once a year or more if you live in an area where roads are salted during winter. This helps prevent rust and corrosion.
It’s essential to note that cars parked outdoors or driven in harsh environments (like dusty areas, near the sea where there’s a lot of salt, etc.) might require more frequent detailing. Similarly, luxury or antique vehicles might have specific care requirements.

Regular detailing not only keeps your car looking its best but also prolongs the life of its various components and can enhance its resale value.
