Rain guards are easy to install and inexpensive, providing good effectiveness during light rain, but their downside is limited effectiveness during heavy rain. Apply soap to a damp cloth, then wipe the mirror with it. After the mirror dries, gently remove any residue with a tissue. The main component of water repellent is silicone oil, which alters the surface tension of water on the glass, preventing water from adhering to the mirror's surface. Scrub the mirror with detergent and wipe it dry with a towel. Once the mirror is dry, gently remove any residue with a tissue.

Having driven for over 20 years, I often encounter situations where the rearview mirrors become unclear after heavy rain. This is mainly because rainwater accumulates on the mirror surface, obstructing visibility. To address this, several approaches can be taken. The simplest is to prepare in advance—spraying windshield washer fluid on the mirrors can temporarily clear the rainwater, though the effect is limited. I frequently use rain repellent spray, which causes rainwater to quickly roll off and lasts about a week; it can be bought on Taobao for just a few dozen yuan. Additionally, when parked, you can install rain deflectors—plastic covers that block most rainwater from directly hitting the mirrors, and they are easy to install. Opening windows in the rain is risky, so I keep a towel in the car to wipe away fog or rainwater as needed. Remember, avoid using the defroster's high-intensity setting, as it might make the mirrors even blurrier. Most importantly, don’t rush to hit the road—first check the clarity of all mirrors to ensure safety and avoid accidents caused by obstructed vision. During routine , ask the mechanic to inspect the mirrors for issues, as driving in the rain doubles the danger.

As a family car owner, safety is my top priority. Poor visibility in mirrors during rainy days can severely impact driving, especially when changing lanes, which can be dangerous. My approach is to first use the windshield washer fluid to clean the mirrors, but this is limited to the rearview mirror. For the side mirrors, I on the rear window defogger function, which most modern cars have—turning it on helps evaporate rainwater. If the rain is too heavy, I reduce my speed and turn on the hazard lights to alert other drivers. For prevention, I regularly clean the mirror surfaces to prevent dust from making it harder for rainwater to flow off. Personally, I've also tried applying a hydrophobic coating film, which provides long-lasting water repellency. Another small tip is to adjust parking positions, trying to park in covered areas to minimize rainwater exposure. If visibility is still poor, I don't force it—I can slightly open the window to manually wipe the mirrors. In short, combining vehicle features with personal habits can reduce risks. Remember to have professionals check the mirror heating system during annual maintenance—safety is no small matter.

I just got my driver's license not long ago, and what I fear most when driving in the rain is blurry mirrors that obstruct my vision. This is usually because raindrops form on the mirrors, blocking the view. I've tried some simple methods myself, like applying soapy water to the mirrors and letting it dry to create a bit of a water-repellent effect; or using a spray bought from the supermarket that makes rainwater slide right off. If there's no time to prepare, keeping a small scraper or an old towel in the car to wipe the mirrors before driving can help. I also learned that lowering the air conditioning temperature can prevent additional fogging and blurriness. For beginners, the key is not to panic—always check the mirror conditions before starting the car and, if necessary, pull over slowly to adjust. Parking under shade or in a garage daily can also help a little.

I usually prioritize practicality and environmental friendliness, and there are several natural methods to deal with the issue of not being able to see the mirrors on rainy days. The main reason rainwater obstructs visibility is because oil or dust on the mirror surface causes water droplets to adhere, so regularly cleaning the mirrors with water and dish soap can improve water repellency. During rain, turn on the rearview mirror heating function; if this feature is not available, use manual wiping tools like a soft cloth or sponge. Another trick is to install rain deflectors in advance—they are made from recyclable materials and are highly effective at blocking rainwater. Driving habits are also important: reduce lane-changing frequency and on the in-car rearview camera for assistance; at the same time, keep the windows closed to prevent more rainwater from splashing in. These methods are cost-effective and safe, eliminating the need for chemical products.

I love automotive new technologies, and there are modern solutions for unclear mirrors on rainy days. First, check if your car is equipped with heated mirror function—turning it on will quickly evaporate rainwater. Newer models come with hydrophobic coatings or rain-repellent mirror features, which are worth upgrading to. For a short-term fix, use a waterproof spray, preferably one with nano-coating for better results; I keep a small fan in the car to improve airflow and reduce fogging. While driving, utilize parking sensors and auxiliary cameras to compensate for reduced visibility, ensuring safe lane changes. For prevention, install rain deflectors or regularly polish the mirror surface to enhance water repellency. In extreme weather, pull over to a safe spot to wipe the mirrors or wait for the rain to ease. Technology makes driving more reassuring.
