Remove dried tree resin stains from the windshield

My car is always under a large spruce. Although I do not have to scrape ice in the winter, but I have resin spots on the disc.

Recently, when cleaning the glass ceramic hob with one of these "razor blade scraper", I came up with the idea whether the thing can not be used on other glass surfaces.

If you have resin stains on a glass, just use the glass ceramic field scraper! Works best with hardened stains, with fresh it's a mess ... Caution! Never try on the car paint!

The area you want to clean must be harder than the razor blade. (Glass, marble, tiles, also metal, etc.) Have fun scratching the disc even during the whole year!
