Here is a general rule of thumb:
If you live inland in an area where your car is free of salty air and sand, and if you don’t have to contend with tree sap, bird droppings and dead bugs, you can wash your car about once a month and still keep it in good shape.
If you live in a polluted environment, near a salty coast or in a wooded area, once a week may be your best bet.
Otherwise, a couple of times a month is a good bet to ensure that you’re not waiting too long to get rid of harmful chemicals, residues, salt, sand, tar, grease and grime.
