There are a number of factors that should be considered and that will influence how often you wash your car. Assuming that your car has initially been thoroughly cleaned polished & protected, a regular wash should simply be undertaken to remove any recent dirt and surface contaminants that have accumulated, restoring it back to its initial clean condition.

Generally the vast majority of vehicles would benefit considerably from regular washing at either weekly, biweekly or even monthly intervals.

A weekly wash will ensure that your car is kept in a clean and contaminant free condition, yet this regularity may not necessarily be required for all vehicles, or possible due to some of the factors mentioned earlier.

If your car is not used daily, does not travel long distances, or is kept in a garage (or a combination of these things) a good wash once a month will still ensure that any dirt and contaminants it may have picked up during that time will be effectively removed.

If you live in a location that means your car will get covered in some form of dirt or contaminants soon after it has been washed, for example – sand, mud or snow & ice, it may not be worth washing on a weekly basis but instead giving your car a thorough monthly wash and then simply rinse off any ‘fresh’ contaminants in the shade on a weekly basis to ensure that an excess of dirt is not left to accumulate.

Ideally, for your car to fully benefit and in order to keep it as clean & contaminant free as possible, a weekly or at least biweekly wash should be undertaken.
