How to repair plastic windshield

Plastic windshields are extremely durable and less susceptible to breakage of glass windshields. Unlike glass windshields, most plastic windshields are safe when placed under tension. However, finding a spare plastic windshield can be difficult. Fortunately, plastic can be repaired with acrylic solvent cement and plastic polishing compounds.


  1. Wash the windshield on both sides with hot water and dishwashing detergent. Clean crack well. Use only a 100% cotton cloth to wipe the windshield to avoid scratching the polished surface. Dirt and grease may form a barrier that prevents solvent cement from melting the broken plastic. A crack can continue to split if not properly cemented.
  2. Tape the area around the crack with painter’s masking tape, leaving a ¼ “edge of plastic exposed around the crack. Solvent cement may scar the finish of a plastic windshield if it spills onto the surface of the windshield. Tape creates a barrier between the windshield and cement.
  3. Fill the applicator bottle halfway with solvent cement. Acrylic solvent cement works for almost all transparent plastics. Using your thumb and forefinger, apply pressure to the sides of the bottle until the liquid is on top of the bottle. Slightly loosen the pressure. You have now created a vacuum inside the bottle, keeping the cement spilling when you tilt the bottle during the application process.
  4. Apply a thin strip of cement along the crack in one side of the windshield. Capillarity will cause the cement to be thrown into the crack. After the cement has dried for two hours, remove the adhesive tape. Apply masking tape around the crack on the other side of the windshield, leaving a ¼ “border around the crack. Apply a thin layer of cement and allow 24 hours of drying time to elapse before proceeding to step 5.
  5. Apply a small amount of buffing compound on a 100 percent cotton cloth. Remove any remaining tape from around the crack. Polish the area around the crack until any residual cement has been polished to. The buffing compound contains abrasives that grind down the residual glue, while still leaving the plastic clear. Wash the windscreen once more, on both sides, with dishwashing detergent. The project is complete.

How to remove ice from the windshield, simple tricks

Removing ice from the windshield is a rather cumbersome task. Therefore, before giving you the tips to remove it quickly and easily, it is advisable to know some recommendations to prevent ice from occurring.

Prevention: how to avoid the appearance of ice

If you plan to park your car outside in winter, you can avoid the appearance of ice by placing, for example, an old blanket and some thickness on the windshield (it would not be bad if you also put rags or pieces of old blanket in the windows and in the rear window). An alternative to blankets can be covers, thick cartons and several layers of newsprint.

Another trick home that gives results the moment you park your car outdoors is pouring a solution of water and vinegar. Concretely, every three parts vinegar a water.

If the ice has already appeared: what NOT to do

If you have not been able to avoid the presence of ice on your windshield (you have forgotten to put blankets, cartons, etc.), you NEVER want to put HOT WATER directly on the glazed surface of your car. The drastic change in temperature can crack the glass. Also, do not put SAL directly on the windshield and scratch immediately with a plastic object. The direct SAL on the glass can cause scratches, in addition to the corrosive power of this element on the surface / body plate.

If there is ice: what you DO

Start the engine of the car, activate the heating and direct the aerators to the windshield. While doing this, lower some of the windows of the car. In case the crystals have some ice or frost in a closed place (it is very rare that it happens, but it can happen), do not have a long time the engine started because of the danger that your carbon monoxide can generate in your health.

With the above, you will get that the layer of ice is reduced slightly. It is at this moment when you should scratch yourself. The best object to realize it is a scraper or scraper that they sell in any store of accessories for the automobile. If you do not have a scraper, an old plastic card (or a credit / debit card that you do not use and that is not valid) can also help you, although its effectiveness is less than that of a scraper.

Before scratching, you can even pour salt water (never, salt by itself) that can help you in the scraping task.

Coolant and alcohol on the windshield. You can also spray the glass with this liquid thanks to its antifreeze properties. It is best to take it out for a few seconds before scratching. Also, alcohol can also help you remove the ice.

Remove the inside fog that produces the cold. The very action of the hot air will defrost the inner zone of the glass. If you want this action to be much faster, in addition to rubbing with a rag, you can also rub the surface with a potato cut in half and then dry with a dry cloth to remove the small liquid generated by the potato when pressed.

How to remove ice from the windshield without an ice scraper

Snow and ice storms can present challenges for car owners. One of the biggest problems facing drivers is to remove ice from the windshield both from their driver and the rear windscreen of the vehicle. The easy answer is to use an ice scraper, but sometimes a driver is trapped in a storm that has created ice on the windshield and does not have an ice scraper in his car. In this situation, a bit of improvisation is required to remove the ice.


  • Start the engine and turn the thermostat in the car as high as possible. Adjust the fan for air circulation inside the car to the highest position.
  • Set the heater to the defrost setting on your vehicle. Usually this is represented by a small picture of a windshield.
  • Check your wallet for a piece of hard plastic. This piece of plastic can be a frequent buyer card from a local grocery store, a wallet-size notecard calendar, an expired credit card, or an insurance card.
  • Choose a card that does not care if it gets damaged a bit. The grocery store frequent buyer card is usually a good option, considering grocery stores will allow you to enter your phone number into the registry instead of scanning your card.
  • Hold the card at a 45 degree angle on the windshield with an edge toughing the windshield.
  • Apply push the card in a direction opposite to you pressure. Typically starting at the end of the windshield and pushing towards the center works best. This will begin to remove ice from your windshield.
  • Remove all light ice scrapes from the windshield with the brush by hand. If possible, use a glove while doing this to prevent your hands from becoming too cold.
  • Use short strokes of three to six inches with the card while scraping your windshield. Allow the combination of friction of the card with the heat of the frost eliminators inside the vehicle to remove the ice.
  • Repeat steps five through seven for each of the car windows.

Tips & Warnings

  • If the ice sheet is very thick, do not try to remove the entire layer at a time. Remove part at a time from the top of the layer, while the frost on your car are weakening the bottom of the layer that is closest to the window. After removing the top layer, the layers closer to the windshield and touching the windshield will be easier to remove.
  • Do not use a plastic card with a toothed edge on it, as this edge may scratch the windshield. A smooth edge will limit the chances of scratching the windshield, but it will not eliminate the risk altogether.

Hiding a crack in a windshield

A windshield cracked can produce glare that can affect your driving.

You can easily repair your cracked windshield in your home with some instruments.


  1. Pour 1/4 cup water into the mixing bowl, then add 1/2 teaspoon salt, 1/2 and 1/2 insect repellent isopropyl alcohol. Stir the contents of the bowl until the salt has dissolved.
  2. Dip the cloth in the solution and rub it against the crack. Still wetting the cloth in the solution and rubbing it against the crack until the solution runs out.
  3. Allow the windscreen to dry for several hours. Isopropyl alcohol and insect repellent react together and soften the plastic cover that is above the windshield glass. Then the salt acts as filler in the mixture of isopropyl alcohol, and insect repellent. Once dry, it is as if there had never been a crack in the glass.


Deciding between the windshield repair or replacement

Check the terms of your insurance and repair contract. The cost of repair or replacement of a total varies significantly depending on your location, your insurance and the type of windscreen. A professional repair is more costly than a home kit, but the result can be considerably less visible.

In Florida, Arizona, Kentucky, South Carolina and Massachusetts, a comprehensive auto insurance will cover the full cost of repair or replacement. If you do not have insurance that covers your windshield, you might end up paying the full price of the repair.

Looking damage near the edge of the windshield

The cracks or fissures on the edge can compromise the structure of the windshield. Even after repair this damage could be a major security issue. Rather than repair the windshield, you should have it replaced.

Consider the line of sight of the driver

The damage produced directly in the line of vision of the driver can interfere with driving the car, even after repair. The most dangerous area is a section of glass 30 cm (12 inches) wide, centered behind the wheel and extending the height of the windshield wipers. If this area is damaged, you should replace the windshield. You can decide to make the repair and then judge visibility.

In this area, two points separated by a distance of 10 cm (4 inches) damage indicate the need for replacement. This pattern of damage can create a blind spot for the driver, thus obscuring the line of sight in both eyes.

Measure the length of the crack. Thanks to modern techniques, most minor cracks to 15 cm (6 inches) can be repaired at home. For longer cracks greater than 46 cm (18 inches), consult a professional first and only repair them on your own if he thinks it is safe. Any crack longer requires a total windshield replacement.

Examines cracks and dents

The damage caused by impacts may or may not be repairable. This depends on their shape and size:

  • Fissures circular or semicircular “target rate” should have a diameter less than 2.5 cm (1 inch).
  • A “star-shaped break” or a point of impact with short cracks extending outward should have fissures that fit within a circle of 7.5 cm (3 inches) wide.
  • Fissures with other forms must fit within a circle of 5 cm (2 inches), not counting the cracks that extend outward.

Check the depth of all damages. The windshields are made ​​of two layers of glass and a layer of plastic between them. If the crack extends beyond the outer layer and the inner plastic, you will have to replace the entire windshield.

The damaged windshield from the inside are rare and even a professional could not be sure how to evaluate them. For security reasons, it is usually best to replace the windshield.
