Does anyone know how to safely remove a mirror button that's glued to the windwhield? I've tried heating with a lighter and twisting, but am afraid to to too much. Also tried a razor blade, but the mount is pretty solid and it won't cut into it. Will a sticker remover spray get into and losen the glue? I have to be careful since some chemicals can screw up the glass (as can heat).

Acetone, and no, i am not familiar with any chemicals whatsoever that can screw up glass, that is why they are stored in glass bottles.

How about an ice scraper? I've seen hard-to-remove stickers on windshields get removed that way. It can be tedious and does require a bit of brute force to knock it loose.

Klixxer is right, acetone will do the job.

But I want to know why you need to remove it?

Edit: I made a mistake in giving credit to the right person.

I apologize Klizzer for calling you Roger and I apologize to Roger for mistakenly using his name.

Oh ffs, just spray acetone on it, it will melt the glue and it will come off easily, if you manage to get the acetone onto something plastic, DON'T wipe it, just let it dry out, wiping acetone on plastic will smear the plastic as acetone melts plastic, which is pretty much why it melts glue too.

It won't do anything to glass though and if you were to apply enough heat to hurt the glass, you would have to sit there with your lighter for hours.

I've spoken with several glass people that say chemicals can etch and fog the glass. Not all chemicals are stored in glass bottles. And supposedly the reason a lot of heat can hurt it is because of the film between the two layers. But the things I tried are what the glass people said to do, but that you take big chance of breaking the glass, so I didn't get forceful with it. One did mention the sticker remover but didn't know what kind/brand. I did ask him about Acetone but he didn't know. Most of the glass people don't seem to have to remove the buttons too often so they don't know a real good way to do it. Or if they do have to, the glass is already broken anyway.

The reason I'm doing it is to install a larger button so my new auto dim mirror will fit without being loose.

Eh, the name is klixxer.
I apologize Klixxer, I am so used to seeing that avatar with Roger's name in car threads I didn?t even notice it was yours.

Please forgive me.

Years ago I had my windshield replaced. The guy that did the job didn't take off the old one, he put a new one on.


I would guess they must come off pretty hard.

Good luck

Will Acetone be able to get underneath the seal to loosen it or will it eat it from the sides, in? Also what would you recommend applying it with? Have any of you actually done this or heard of it being done?

The windshield guys I know used a heat gun on the outside of the glass, and worked the button with pliers until it came loose.
You do run a risk of messing the glass up, though.

Heat will get it off; they fall off all the time in hot weather.

Yeah, I've put on a few that have fallen off for people. You would think that it would have come loose when I held a cig. lighter to it, since it was too hot to touch without gloves. It's hard to imagine a hair dryer could get it hot enough, and as hot as the lighter held directly on it, without harming the glass.

Excuse me but that would mean that the chemical could penetrate the glass, i would like to know which chemical can do that.

Acetone will be able to get between the button and the glass and it will melt the glue without any damage to the glass.

When my mirror fell off (it comes unglued every three years or so) it left this nasty glue spot.

When I got it glued back on, the guy just hit it with a razor and it came right off.

i was told that you cant get it off, i wanted mine moved up a bit because when i got my new windshield it was put on lower then before, they said that its so strong that the only way to remove it was to break the glass

I have removed many things with acetone, stickers, those little thingys connected to alarms with a red diode etc.

Just keep some paper underneath and spray it on using the bottle, as i said, if you get it onto anything plastic or painted, don't wipe.
 

I soak the buttons that I remove with acetone and then using a twisting motion, remove them.

Only thing i can think of that would be that hard to get off would be industrial silicone, but they don't use that, acetone will melt any glue except silicone based glues.

I used industrial silicone to attatch a spoiler since i didn't want to drill holes, that was a stupid thing to do, now it won't come off without removing the paint.

Acetone or alcohol and waxed dental floss. Use the dental floss to saw through the glue seal once the solvent has softened it.

Alcohol will not do much but otherwise that is an extremely good idea. Just act fast when you have put on the acetone it evaporates quickly.

Depending on the type of glue, it will either become soft and spungy (sp?) or it will just dissolve the glue completely.
