What to Do When the Rearview Mirror Gets Wet on Rainy Days?
3 Answers
Installing rain guards on the rearview mirrors is a relatively cost-effective solution. These guards are typically mounted on the door windows and prove to be quite effective. Applying a layer of soapy water on the rearview mirrors works remarkably well, maintaining clarity for 2-3 hours even in heavy rain. There are various hydrophobic agents available on the market that prevent water from adhering to the rearview mirror surface. These glass hydrophobic agents come in two forms: those that are applied by wiping and those that come in spray form.
When it rains, water droplets on the side mirrors can be really annoying while driving, as they block the view of the road behind. Simply put, you can buy a water-repellent spray to apply on the mirrors—this makes the rainwater roll off automatically without sticking to the surface. For cars equipped with heated mirrors, just turn on the switch to warm them up and dry the droplets, which is very convenient. If your car lacks these features, applying soapy water or a dedicated anti-fog solution before heading out can serve as a temporary fix. If water accumulates too much while driving, find a safe spot to pull over and wipe the mirrors—don’t force it. Additionally, drive slower and increase your following distance in heavy rain to avoid rear-end collisions. Make it a habit to clean your mirrors regularly to prevent dirt from worsening water retention. In short, a small investment ensures safety—prioritize dealing with it promptly.
When encountering accumulated water on the rearview mirror on rainy days, as an experienced driver, I'd like to share some tips: First, keep a small towel in the car and wipe the mirror surface when parking. Sometimes, applying a diluted layer of household detergent can prevent rainwater from sticking—it's effective and costs nothing. If visibility becomes poor while driving, immediately slow down, close the windows to avoid rain splashes, and check if the heating function can evaporate the moisture. If visibility remains poor, pull over safely, avoiding hazardous roadside areas—safety comes first. Remember, driving in the rain is inherently risky, so regularly check and clean your rearview mirrors—don't wait for an accident to regret it. These practical tips have helped me a lot; give them a try for peace of mind.
