A couple of days ago we had a pretty big winter storm here in Chicago with a nice ice storm to start it off. My truck was a solid sheet of ice underneath the frozen snow the next morning. It took me literally half an hour of scraping away plus two cans of de-icer before I could barely clear a spot big enough to see out the windshield. I've never seen such stubborn ice before. This will never happen again, because I went online and found the ultimate killer ice scraper, the Heated Ice Scraper! Just charge the cordless scraper and when you're ready, flip the switch. It instantly heats up and melts the ice away. Too bad it doesn't have a brush on the back, but it's definitely a great tool to have in your arsenal against annoying winter snow and ice!
