Fog on rear window - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

JSK · 08-15-2012, 12:52 PM

I'm new to the forums so hopefully this isn't a dead topic. I have this patch of condensation on the rear window right above the break light and it never goes away. Even on a hot dry day it is still there. The only way I can get rid of it is if I put on the rear defrost. I haven't tried any anti-fog products yet. Anyone else have this issue?

Yeah, myself and a few others have the fog triangle above the third brake light. Happens in a lot of smaller coupes though. I've got bigger fish to fry before that one.

I had it, drove me nuts. Then I cleaned my back window on the inside and haven't seen it since lol

Thanks, I'll just give it a clean and see what happens.

I don't think its fog, it's some kind of residue. Probably from all the glue vapors.
It looks like I might have some under my tint, I'm going to have to look at again next time I give it a good cleaning.

I also had the fog triangle. After I gave it a good clean with stoners invisable glass, it never came back.

I did a clean and had it reappear... I think having the energized head of a 4 yr old accelerated the return. Since the last clean it hasn't reappeared yet but my daughter hasn't been riding with me to day care either.

When I saw this thread, I went downstairs to my garage and windex'd it right away. I do notice the triangle fog usually appears at night when the air cools down a bit + the humidity.
