Winter care

None of this is expert advice. It's what people worked out for themselves, usually the hard way — what actually helped, and what they'd tell someone standing where you are. Take what fits and leave the rest.

How this was put together

If you only read a few

  1. Cover your windshield with cardboard, an old sheet, or a car cover before sleeping to prevent frost formation.

    • Fabric may freeze to the glass if it rains, snows, or there is freezing rain.
    • Cardboard may need to be replaced frequently (2-3 pieces per winter).

    • Tuck a corner of a beach towel under your car door and drape the rest under the wipers to cover the windshield.1
  2. Apply Rain-X or Windex to the windshield.

    It may help prevent ice buildup and keep views clear when it rains.

    • One person reported never finding it that great.

  3. Use de-icer washer fluid to soften thick ice and clear light frost.

    It contains alcohol which melts ice instantly except for large buildups.

    • De-icing sprays will kill the non-stick coatings on wiper blades.

  4. Raise your wiper blades off the glass before parking in freezing weather to stop them from sticking.

    This helps keep the wipers in good condition during winter and makes it easier to clean the ice with a scraper.

    • Covering them with old socks has not been found to make a big difference by some.

  5. Clean the windshield while it is warm to make removing film and streaks easier.

    It is much easier to remove film and streaks when the glass is warm.

  1. use newspaper to wipe the windshield for a lint-free, streak-free finish

    newspapers don't leave lint

    • few people have newspapers available

  2. Contact local independent auto glass businesses for quotes instead of national chains.

    They may charge half the price and can often come to your home.

  3. Start the car with defrost on full heat and fan, then scrape side windows, rear windshield, and finally front windshield.

    This sequence gives the maximum amount of time for the defrost system to work on the front windshield.

  4. Use Glass Cleaning Clay to remove stubborn contaminants from the windshield surface.

    It does a great job removing contaminants.

    • Takes a while.

  1. If your windshield has cracks or chips, defrost it slowly to avoid thermal shock that can lengthen the damage.

    Rapid temperature changes can cause existing cracks to lengthen.

  2. Place a pantyhose or sock filled with unused cat litter under your seat to absorb moisture and prevent window fogging.

    It stops windows from fogging up overnight.

    • Ensure the cat litter is unused; otherwise, the car may smell like cat feces, which is very noticeable if you do not own cats.

  3. Fix leaky window seals or rusty holes in the floor to stop external moisture from entering the cabin.

    These are causes of interior moisture.

  4. Point side air vents directly at the windows.

    This keeps air circulating around them.

  5. Knock snow off boots before entering the car to prevent melting snow from evaporating onto the windows.

    Snow melting on mats evaporates back into the air and fogs the windows.

  6. Try using melamine foam or Magic Erasers to clean tough spots on windshields.

    One person reported good luck with this method.

  7. Wipe down the inside of windows with a microfiber cloth to keep them clean and discourage fog formation.

    Clean glass helps discourage fog formation.

  8. Remove felt soundproofing under floor mats if it traps condensation.

    The felt soundproofing is identified as a culprit for trapping moisture.

  9. Engage the air conditioning alongside the defogger.

    It extracts excess humidity from the cabin and dries the airflow directed at the windows, accelerating clearing.

  10. Keep a toothpick in your car to realign drifting windshield washer nozzles.

    One person kept a toothpick specifically for this purpose because their sprayer would slowly drift down.

  11. Repair a leaking heater core if windows are consistently fogged on the inside.

    A leaking heater core can cause persistent interior fogging.

  12. Use the defroster to blow warm, dry air onto the windows, waiting until the engine coolant temperature has peaked slightly before turning it on.

    Warm, dry air displaces moist air.

  13. Clear ice off the windshield first if visibility is impaired; do not drive until the windscreen is clear.

  14. Lower your sun visors while using the defroster on high to keep heat concentrated on the lower part of the windshield.

    It prevents heat from escaping halfway up the window, keeping it focused on the area where visibility is most critical.

  15. Verify that the pump has not failed before replacing windshield fluid lines or washer heads.

    Replacing parts unnecessarily is wasteful if the pump is the actual point of failure.

  16. wipe the windshield with Everclear (grain alcohol) after using window cleaner to remove residue

    it removes residue left by window cleaner

  17. use aerosol glass cleaner rather than liquid spray types for better application

    aerosol is preferred for commercial-style windows
