Industry experts generally recommend washing your car about every two weeks as part of regular maintenance. This frequency helps keep the exterior clean and free from contaminants like tar, road debris, bird droppings, salt, and grime that can damage the paint and cause rust over time

. However, the ideal washing schedule can vary depending on several factors:

• Climate and season: In winter or regions where salt is used on roads, more frequent washes may be necessary to prevent corrosion

. In rainy or dusty environments, wash frequency might also increase or be adjusted based on weather conditions

• Driving habits: Frequent driving on dirt roads or through areas with heavy grime may require more regular cleaning

• Storage: Cars kept in garages or driven less often can be washed less frequently

• Protection: Applying wax or ceramic coatings can reduce how often you need to wash by protecting the paint from contaminants

Washing your car too often is generally not a concern if done properly, but using harsh automatic washes too frequently might cause damage. Hand washing is often preferred for better control and less risk of scratches

. In summary, washing your car every two weeks is a good general guideline, but adjust based on your local conditions, driving habits, and protective treatments on your vehicle
