When those bugs smash into your car at 55 miles (88 kilometers), per hour, they really stick. Give your grille a spritz of nonstick cooking spray so you can just wipe away the insect debris.
If those tattered old bumper stickers on your car make you feel more nauseated than nostalgic, it’s time to break out the vinegar. Saturate the top and sides of the sticker with undiluted distilled vinegar and wait 10-15 minutes for the vinegar to soak through. Then use an expired credit card (or one of those promotional plastic cards that come in the mail) to scrape it off. Use more full-strength vinegar to get rid of any remaining gluey residue. Use the same technique to detach those cute decals your youngster used to decorate the back windshield.
It’s bad enough that your car grille and hood have to get splattered with bugs every time you drive down the interstate, but do they have to be so darn tough to scrape off? The answer is no. Just spray some WD-40 on the grille and hood before going for a drive and most of the critters will slide right off. The few bugs that are left will be easy to wipe off later without damaging your car’s finish.
