How do you use a windshield snow cover?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
A windshield snow cover sits over the outside of the glass overnight so frost and snow build up on the cover, not the windshield. Secure the flaps in the doors, set the wipers under or over the cover per its design, and shake off the snow before you fold it. A plain blanket can freeze to wet glass and is a poor substitute.
How to fit a windshield snow cover
Most covers drape over the outside of the glass and anchor with flaps shut in the doors.
- 1
Drape it over the glass
Lay the cover across the windshield so it reaches the edges and the flaps hang into the door openings on each side.
- 2
Shut the flaps in the doors
Close the doors over the side flaps so the cover is pinned at the edges. The pinch holds it against wind better than straps or magnets.

Set the wipers
Place the wipers under or over the cover the way the cover’s instructions show. Some covers want the blades tucked beneath; others have sleeves the arms pass through.

Shake off before folding
In the morning, open the doors, pull the cover off, and shake the snow clear before you fold it. Folding a wet, snowy cover makes a mess of the interior.
A blanket can freeze to the glass
A plain blanket laid over a wet windshield can freeze to the glass overnight, and pulling it free can leave fibers stuck to the surface. A purpose-made cover sheds moisture and lifts off clean. See our guide on keeping a windshield from frosting overnight.
Common myths about windshield covers
Any cover works as well as a snow cover.
A towel or sheet absorbs moisture and freezes to the glass. A purpose-made cover sheds water and lifts off clean, which is the whole point.
A cover means you never scrape.
A cover keeps frost and snow off the glass it covers, but ice can still form on the side windows and mirrors, and a storm can find the edges. Keep a scraper for the rest.
More questions about windshield covers
Do windshield covers work for snow?
Yes. Snow builds up on the cover instead of the glass, and you pull the cover off to a clear windshield. Shake the snow off before you fold it.
Do windshield covers work for frost?
They do. The cover keeps frost from forming on the glass beneath it, so the windshield is clear in the morning while the side windows may still need scraping.
Can I put a blanket on my windshield?
A blanket can work in a pinch, but it absorbs moisture and can freeze to wet glass, leaving fibers behind. A purpose-made cover sheds water and lifts off clean.
