What to Do When Car Mirrors Are Blurred by Rainwater?

Use a clean, damp cloth to apply soap or dishwashing liquid, then evenly wipe the rearview mirror with the soapy or detergent-coated cloth. Installing rain guards on the rearview mirrors can effectively prevent rainwater from dripping onto them, reducing water droplets on the mirror surface that obstruct visibility. The installation method is similar to applying window film, effectively preventing raindrops from lingering. Additionally, it offers anti-fog and anti-glare benefits. Convert the rearview mirror into an electric heating type. The electric heating rearview mirror uses a set of heating wires embedded behind the mirror to accelerate the evaporation of water droplets on the surface.

Recently discovered a handy trick for the rainy season: apply soap in circular motions on the mirror surface, spread evenly, wait a few minutes, then polish with a dry cloth. This causes rainwater to form small beads and slide off. Personally tested to last about two hours. Remember to dry the side windows before driving, otherwise the 'water curtain' effect can be more annoying. Don't forget to turn on the heated mirrors—most cars priced above 100,000 yuan now come with this feature. Also, press the rear window defogger button to reduce fogging caused by temperature differences. If all else fails, keep a highly absorbent microfiber cloth in the door compartment for quick wipes at red lights. I always keep a defogging spray in my car; spraying it once before rainy weather keeps it effective for a week.

Driving in the rain with poor visibility can be nerve-wracking. My experience is to first turn on the AC and direct it toward the windshield, setting the temperature lower for faster defogging. For water accumulation on the rearview mirrors, you can buy rain repellent films online—twenty bucks for a set that lasts three months. Apply the film in a wind-free environment, spray enough installation fluid, and slowly scrape out the bubbles. Anti-fog spray is also worth buying, as its special formula breaks the surface tension of water molecules. It’s best to keep a mini squeegee in the car—much more convenient than a towel. If your modification budget allows, upgrade to anti-glare blue mirrors with heating functionality, which also helps against high-beam offenders at night. Remember to reduce speed in the rain, as water droplets on the mirrors can scatter the light from trailing vehicles even more severely.

The most practical solution is to apply anti-fog spray on windows before departure. Choose products with hydrophobic ingredients and apply them on both side windows and windshield - this even reduces wiper effort. For mirror water accumulation, apply a thin layer of car wax then polish it; this lasts longer than soap. Turn on the air recirculation mode to prevent window fogging. When temporarily stopping to wipe mirrors, remember to activate hazard lights. New drivers must never attempt to wipe windows while driving - it's extremely dangerous. During heavy rain, always check blind spots by turning your head before changing lanes, don't rely solely on mirrors. Older vehicles can have heated mirrors installed for about a hundred yuan at any auto repair shop.
