3 Reasons Your Windshield is Pitted

Update On

Is the sun’s glare making driving difficult? While the sun is setting or rising, it sits at eye level in the sky. This can block your vision temporarily and pose a real danger to you and others on the road.

If you’re having significant problems with the sun’s glare, it may be getting through your windshield through tiny holes in your windshield called pits. Windshield pitting is the damage caused by objects hitting your windscreen as you drive. There are three major reasons why this happens.

3 Reasons Your Windshield is Pitted

How Does A Windshield Get Pitted

The most obvious explanation for window pitting is damage from foreign objects. As your drive, pebbles, insects, and debris hit your windshield at high speed. This really cannot be avoided.

A second major cause of window pitting is excessive speed. If you drive on a highway a lot, your windshield will come into contact with more pebbles kicked up by other cars. They’ll hit your windshield faster, and this will accelerate the development of pitting.

The second reason windshield happens and can happen faster on your vehicle is if you use the highway regularly. You tend to drive faster on the highway meaning that objects get lifted from the highway and hit different windscreens as drivers drive by. Since everyone is moving fast, highway drivers get their windshields pitted faster.

Thirdly, your windscreen will get pitted faster if you drive in a dusty or sandy environment. Sand, road debris, and dust make up the objects that can damage your windshield. Driving in an environment with a lot of these potential projectiles also makes your windshield get pitted faster.

How Do You Get Rid Of A Pitted Windshield?

How Do You Get Rid Of A Pitted Windshield

Repairing a pitted windshield may work if the damage is minimal, but it will not return the windshield to as-good-as-new. The easiest and safest way to get rid of a pitted windshield is to replace it with a new windshield.

If you do want to repair the windshield yourself, this process could work for you.

Clean the windscreen

You will first need to clean the windshield to remove any particles. The cleaning process also removes any oil residue and dirt accumulated on it. You will need a soft nylon bristle brush and some liquid dish soap. The brush ensures all stuck particles get dislodged while the dish soap removes the grime.

Apply polishing compound

For this step, you will need a glass polishing compound, a microfiber applicator or foam, a variable speed drill, safety goggles, and gloves. The glass polishing compound will ideally have cerium oxide, a glass abrasive that will slowly level the glass to the level of the pits so that the windshield is on the same level.

First, pour some polishing compound onto the applicator and spread it across a portion of the windscreen. Divide the screen into at least four parts you can efficiently work on. Once you have applied the compound, set the drill to low and use it to polish the glass using a 325 grit pad.

Continuously drip a little water from a sponge. This action dislodges glass bits from the pits and keeps the compound moist so it does not dry and creates scratches.

Clean the windscreen, again

You will then need to repeat the first step by taking a brush and dish soap to clean the windscreen. This process now removes the compound and glass flakes from the windshield. It also cleans the pits so you can see your progress and determine how much more polishing you need to do.

You can then apply the polishing compound and polish the windshield, remembering to keep it moist with water as you go along. Repeat the cleaning and polishing process until satisfied with the results. Finally, you can apply rain repellent to the windscreen to help slow abrasion and give you better visibility in wet conditions.

How Does A Windshield Get Pitted?

A windshield gets pitted when the vehicle is driven in conditions that expose it to flying objects on the road. These objects, like sand, cause minute cracks, pits, and craters in the windshield. Over time, these deformities increase, causing light to get scattered in beams or glares.

Can Small Pits In Windshield Get Fixed?

You can fix small pits in the windshield by buffing or polishing the glass. You can use good-quality glass polish to remove these small pits. You use the polish compound to slowly sand the glass around the pits until it levels with them.

This process requires patience with a need for some expertise. You can employ the services of an expert buffer to get the best results. Understand that this process works only for minor pits, as polishing a windshield with large pits will weaken the glass and make it hazardous.     

Can A Windshield Be Buffed Out?

You can buff out a windshield depending on the extent of the scratches. You can buff out mild scratches either using a DIY kit or getting it done by a repair shop. You can determine a mild scratch by passing your finger across the scratch without getting it stuck at the scratch. Pitting damage or deep scratches should be repaired by auto glass repair experts.

Should I Fix A Pitted Windshield?

The damage on your pitted windshield will determine whether it is wise to repair or replace it. You can fix mild windshield pitting, but extensive pitting requires a windshield replacement. Repairing a damaged windshield can weaken it when it thins the glass in certain areas. Replacing the windshield is the safest option.

Do Windshield Pits Crack?

Do Windshield Pits Crack

Windshield pits have the potential to crack your windshield. As the pits increase, the windshield weakens enough to crack it with the slightest impact. Because the pits are made with minute objects like sand particles, they will not create immediate cracks on impact. But they will lead to cracks in the future.

Why Is Windshield Speckled?

Why Is Windshield Speckled

Your windshield may be speckled due to one of two reasons. One reason occurs during manufacture. Windshields are made by laminating two glass pieces using either polyvinyl butyral or ethylene-vinyl acetate. The process of bonding these two glass pieces may have the process corrupted by little specks caught in between the glass.

The other reason that may speckle your windshield is pitting caused by tiny objects. These speckles only offer a distraction to the keen driver.


You can get by with a pitted windshield if it does not interfere with your driving. If the pits in your windshield are interfering with your vision or giving your glares from light, then you should consider replacing the windshield. You can also consider repairing the windshield if the pits are not so advanced. Has your windshield been pitted recently? How did you deal with it? Reply in the comments section below.
