So I got my first ever parking sticker on my windshield. It was about half the size of an A4. Luckily, the day was raining so when I removed it, it wasn't that hard. I just used an exacto knife and scraped off the sticker (in a thousand pieces lol). But if the day had been dry and hot, the sticker would probably have sealed in stronger and taking it off would have been a PITA. What are some of the best methods to taking them off? I've heard people say to use things like windex, alcohol, nail polish remover, or vegetable oil. I wonder if I pre-prep my windshield (just the corners where they usually stick em) with a light smear of car wax would make the sticker easy to remove later? Has anyone ever tried that? The reasoning is because I believe car wax would actually stay on the glass for a very long time even through rain and snow, and not easy to wipe off. So when the guy places those parking stickers on there, it might not stick completely to the windshield and makes it easier for me to peel/scrape it off. This is just theoretical. Of course, the best method is to simply not park where you are not supposed to park (duh). But still, sometimes people will just stick em on to piss you off I guess so better to do my homework.
