Knowing how often to wash your car should be easy, but it rarely feels that way. Some weeks, your car looks fine. Other weeks, it feels dirty after just a few days. Weather, roads, and daily driving all play a role, which is why there is no single answer for everyone. The quick answer is that most drivers should wash their car every one to two weeks. That timing works well for everyday driving and normal conditions. You may need to wash more often during winter, pollen season, or whenever you notice visible grime building up.
This guide explains why that schedule works, what causes it to change, and how to tell when your car needs attention sooner. We will also touch on interior care, since daily life often creates messes inside faster than expected. If staying consistent feels challenging, knowing your nearest car wash can make routine care easier to maintain.
