How Do You Protect Car Glass During Long-Term Storage?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
Clean the glass, close the windows or leave them barely vented indoors, set moisture absorbers inside, lift or wrap the wipers, and use a breathable cover. Fix any chips before storage, because a break that sits for months collects dirt and runs when temperature swings return. A climate-controlled space is best.
Before the car goes to sleep
- Wash and dry every pane so grit and water spots do not etch into the glass over months.
- Inspect for chips and cracks and have them repaired — a filled chip is stable; an open one is not.
- Clean the wiper blades so they do not bond to the windshield.
- Check the sunroof and window seals for gaps that let in moisture or pests.
- Top off the washer fluid with a winter blend if the car will see freezing temperatures.
What protects the glass while it sits
- Closed windows, or windows cracked just a finger’s width in a dry indoor space to vent moisture.
- Moisture absorbers or desiccant packs on the floorboards to keep the cabin dry and the glass from fogging.
- Wiper arms lifted or blades wrapped in cloth so the rubber does not cure flat against the windshield.
- A breathable fabric cover rather than a plastic tarp, which traps condensation against the glass.
- A sunshade behind the windshield to cut ultraviolet load on the interior and the camera housing.
Putting the car into storage
A short routine at the start saves a bigger problem at the end.
- 1
Repair the glass first
Have any chips filled before storage, because a break left for months takes dirt and resin poorly when you finally address it.
- 2
Clean and dry everything
Wash the glass, dry it fully, and leave the doors open briefly so the cabin is not sealed wet.
- 3
Set the windows and vents
Close the windows for outdoor storage, or crack them a finger’s width in a dry garage to let moisture escape.
- 4
Position the wipers
Lift the arms or wrap the blades so they do not bond to the glass over a long sit.
- 5
Cover the car
Use a breathable cover that fits, and avoid plastic sheeting that holds condensation against the glass.
Fix chips before storage, not after
A chip that sits untouched for months collects dust and moisture into the break, and the resin that would have filled it cleanly now has to work around contamination. Have the chip repaired before the car goes to sleep — it takes 20 to 30 minutes and costs far less than the replacement it might prevent.
More questions about storing a car and the glass
Should car windows be up or down in storage?
Up, for outdoor storage, to keep weather and pests out. In a dry indoor space, cracking them a finger’s width helps vent trapped moisture so the glass does not fog.
Will a windshield crack get worse in storage?
It can, if temperature swings push on the break. A stable chip in a climate-controlled space may hold, but the safe move is to repair it before storage so there is nothing to spread.
Do I need to remove the wipers for long-term storage?
Lifting the arms or wrapping the blades is enough. The goal is keeping the rubber from bonding to the glass, which leaves streaks and tears when you finally use them.
Is a car cover good or bad for the windshield?
Good, when it is breathable. A fabric cover protects the glass from dust and UV; a plastic tarp traps condensation and can haze the surface over time.
