Most drivers assume car washing is about vanity, but to a professional detailer, it’s about protection. Dirt, grime, and road salt don’t just look bad; they quietly eat away at your car’s paint, trim, and undercarriage. A neglected wash schedule can shorten your vehicle’s life, reduce resale value, and make every future cleaning harder. Yet washing too often (or the wrong way) can also cause damage. I’ve talked to several of my friends (both former and current detailers), and here is how often you should really be washing your car.
