A bathroom mirror fogs up during a shower due to condensation. The warm, moist air from the shower meets the cooler mirror surface, causing water droplets to form.
Showers can turn our bathrooms into steam rooms. As hot water flows, it releases steam into the air, increasing humidity. This steam then lands on cooler surfaces like mirrors, forming tiny droplets. It’s a simple process, but it can be quite annoying when you need a clear mirror.
Understanding why this happens can help you find ways to prevent it. In this blog post, we will explore what causes this fogging and share tips to keep your bathroom mirror clear.

Science Behind Fogging
Warm water from the shower creates steam. Steam rises and touches the cool mirror. This causes condensation. Water droplets form on the mirror. This is why it fogs up. The mirror surface is cooler than the steam. This temperature difference causes fogging.
Temperature plays a key role. Hot steam meets the cool mirror. This creates fog. Higher temperatures mean more steam. More steam causes more fog. The mirror stays cool because it does not heat up quickly. The difference in temperature makes the fog appear.
Preventing Mirror Fog
Using proper ventilation helps keep mirrors clear. Open a window if possible. This lets steam escape. Use an exhaust fan during showers. This will pull the moisture out. Keep the bathroom door slightly open. Fresh air can come in. These methods reduce the amount of fog on mirrors.
Anti-fog sprays work well on bathroom mirrors. Apply the spray before showering. It creates a thin layer. This layer prevents moisture from sticking. Soap and water can also help. Rub a bar of soap on the mirror. Then wipe with a dry cloth. Shaving cream works too. Apply and wipe it off. These treatments keep mirrors clear.
