If a stone or some other small piece of road debris cracks your windshield, it may be possible to fix it with the following household items—packing tape, super glue, or clear nail polish—as long as you catch the damage early on. If the damage is severe, however, it is recommended you have it professionally repaired or replaced.
If you regularly drive, chances are you’ll have to deal with a cracked or chipped windshield at some point. After all, it’s not exactly uncommon for small rocks to be kicked up by a vehicle’s back tires. But if the damage is relatively minor, it may not be worth getting the glass professionally repaired—and you may be able to fix the crack yourself.

How to fix a cracked windshield with household items

Whether it’s caused by a rock flung up by the vehicle in front of you or a freak hailstorm, a cracked windshield can be an incredibly frustrating experience—especially if the damage isn’t enough to warrant a full professional fix.
But doing nothing isn’t a great option either, as it will allow the crack to worsen over time, in which case you’ll definitely have to pay to get the windshield professionally replaced. Fortunately, there are a few methods for dealing with a cracked windshield using everyday household items—we’ve outlined a few of the best below.

Packing tape

It might not seem like it, but clear packing tape is actually one of the best—and easiest—ways to temporarily fix a cracked windshield. To do so, follow the instructions below.
  1. Use 0000-grade steel wool to clean the glass around the crack. This will ensure the surface is as clean and free of dirt as possible, allowing the tape to better adhere to the windshield.
  2. Apply a strip of clear packing tape over the cracked area. You should only need one strip of tape, as any large cracks should be professionally repaired immediately.
  3. Firmly press down on the tape to adhere it to the glass. Make sure it is lying as flat as possible.

Super glue

Similarly, super glue can be used to temporarily repair a cracked windshield. Here are the steps you’ll need to follow:
  1. Thoroughly clean the area around the cracked glass. Take care not to get any cleaning liquid into the crack. Let the area dry before proceeding.
  2. Use scissors to cut off the tip of your super glue, and then apply a small amount to the affected area.
  3. Take a cotton swab and spread the glue to fill the entire crack. You’ll need to do this quickly before it starts to dry.
  4. Allow the glue to set up and dry for the next few hours. Once dry, use glue remover to clean up any excess.
For added protection, it’s recommended to put a clear strip of packing tape over the crack once the glue has dried. 

Clear nail polish

Our last—and least reliable—method of repairing a cracked windshield at home is to use clear nail polish as a temporary filler material. If you decide to go with this method, you’ll need to:
  1. Park your vehicle underneath a shaded area. This will ensure the nail polish doesn’t dry too fast.
  2. Clean the area around the crack or chip, taking care not to get any fluid into the crack. Allow the area to dry completely.
  3. Use the nail polish applicator to apply an ample coat of clear nail polish into the crack. Make sure the polish is even with the glass.
  4. Move your vehicle back into the sun and allow the nail polish to dry for a few hours.
  5. Cover the nail polish-filled crack with a strip of clear packing tape.
Key Takeaway Remember, none of these DIY fixes with household items are meant to be permanent—you should always have a cracked or chipped windshield professionally repaired as soon as possible. If you can locate one, try to find a shop that uses resin injection to repair the cracked glass.

Does car insurance cover a cracked windshield?

A basic car insurance policy, or one with
liability coverage
only, will not cover a cracked or broken windshield. However, this doesn't mean your car insurance policy can’t cover glass damage—you’ll just have to pay extra for this type of coverage.
If you upgrade your insurance policy to include
comprehensive coverage
, you can rely on your insurance company to cover a cracked windshield, minus your deductible. Some companies also offer a $0 deductible or full glass coverage, so check with your insurer if you’re interested.

Generally speaking, the best way to temporarily fix a cracked windshield with household items is clear packing tape.  Use 0000-grade steel wool to clean the area around the crack, making sure it is free of debris, and apply a strip of clear packing tape over the entirety of the crack.
If you don’t fix a cracked or chipped window—temporarily or at all—the damage will worsen and become a potential safety hazard. Without any sort of filler or adhesive to hold the glass in place, extreme temperatures, rough terrain, or even just normal use can cause the crack to expand or even shatter.
