What are the tricks for waterproofing rearview mirrors after rain?

Rainy day rearview mirror waterproofing tricks: 1. Soap waterproofing - Use a wet towel to apply soap evenly on the car's rearview mirror, let it sit for 3 to 5 minutes to dry. This method has good waterproofing effects and very low cost, but the duration is short, usually lasting only about 2 hours. 2. Shower gel method - Provides slightly longer waterproofing duration than soap, but is less effective than soap in heavy rain conditions. 3. Rearview mirror rain guards - These can provide some waterproofing, but are ineffective in heavy rain. Low-quality rain guards may easily fall off and can obstruct the driver's view when turning. 4. Glass water repellent - Contains silicone oil components that resist water adhesion and offers relatively long-lasting waterproofing.
Here are some practical tips I've learned for keeping rearview mirrors water-resistant after rain. The first trick is to wipe them with soapy water: use a damp cloth dipped in soapy water to gently clean the mirror surface, then let it dry. Once dry, rainwater will bead up and roll off instead of blurring your vision. This method is super economical and eco-friendly, much more cost-effective than commercial products. I've been using this on my car for over a decade, applying it before every rainy season, and the results are consistently reliable. The second tip is regular waxing—applying a thin layer of liquid car wax creates a protective film that enhances water resistance for longer periods. Also, always check your windshield wipers before driving; don’t wait until they’re cracked to regret neglecting them. Safety comes first when driving in the rain, and these small tricks can keep your vision clear and reduce accident risks—especially useful for long-distance drivers like me who make it a habit. The third trick is investing in a waterproof spray; there are specialized rain repellents on the market that take just minutes to work and last for months. In short, early preparation brings peace of mind—don’t wait until your vision is blurred to panic.
