Why is my windshield fogging up on the inside?

The inside of the windshield has been getting really foggy recently. I can’t even drive sometimes because it’s so cloudy and I can’t see through it. What is happening? Why is my windshield fogging up on the inside?

That sounds so frustrating! Your windshield is fogging up on the inside because of a difference in temperature—and it could be dirty, too.
Breathing inside the car can cause moisture to build up on the inner side of the windshield, especially when the outside temperature is colder than your breath. The more people exhaling in the car, the worse the fogginess.
Condensation of moist, warm air may also cause fog inside the windshield. This tends to happen when it is a humid day and your air conditioner is forcing cold air onto the windshield.
To solve your windshield fogging up on the inside, run your air conditioner on the defroster setting and toggle off the recirculation to bring dry air inside. It can help to leave a window slightly open, too.
It can be tempting to wipe away the condensation, but we don’t recommend it. Wiping can leave smudges, which makes it difficult to see through the windshield. Dirty windshields hold more grime. Use an ammonia-based cleaner to help prevent fogging, and use a squeegee to remove it neatly.
Safe driving is mostly within your control (like not driving when you can’t see out the windshield)—but it’s not always something you can determine. That’s why a great
