How to Remove the Small Round Mirror from the Car Rearview Mirror?

[ThomasFitz]

First, moisten the area where the adhesive of the small round mirror is attached with alcohol. Next, use the hot air setting of a hair dryer to blow on it. Don't worry about whether the heating will damage the glass. After blowing hot air for a while, the small round mirror will come off. Any remaining adhesive can be gently wiped away with alcohol to ensure no damage to the rearview mirror.

I've taken off those small convex mirrors from my car a few times while doing modifications, and it wasn't that hard but you gotta be careful. Those things are usually stuck on with double-sided tape, so you'd better prepare some tools like a hairdryer or heat gun on low setting to blow hot air for a few minutes to soften the adhesive, then slowly pry it off from the edge using a plastic card (like an old credit card). Never use metal tools, or you might scratch the mirror glass – that'd be a real bummer. If there's leftover adhesive, just pour some rubbing alcohol on it and scrub it off. After removal, you can either install a new one or just toss it, but I'd recommend cleaning the mirror surface thoroughly to ensure better adhesion next time. These small mirrors help expand your field of vision while driving, but if they're not positioned right, you'll need to adjust them, so learning this trick is pretty handy.
