How To Clean Windshield Haze (Easily)


Windshield haze can be very annoying, but also dangerous to experience while driving a vehicle. When it is dark or raining, a windshield haze increases the amount of glare and decreases your overall visibility

How do you fix this? The answer may be easier than you think. Stick around and I will give you all the necessary tools to clean that unwanted windshield haze and give you a clean windshield with one less distraction behind the wheel.

Can you remove haze? and Why do I have it?

There are many possible reasons as to why the inside of your windshield has a film:

1. Smoking

Smoking or vaping in your car is never a good idea! Not only will the smoke sink into the fabric on your seats, but it will leave a grimy residue and a splotchy windshield, that you will have to spend your day cleaning. Using these products outside of your vehicle will save your car’s value and help you keep the interior appearance pristine. 

2. Parking in the Sun

As innocent as it may sound, parking in the sun could be causing an undesirable film and haze to coat your windshield. When you park in the sun, the sun comes through the glass and heats up the interior of the car. When items such as your dashboard, seats, and floor mats get hot, they release oily airborne contaminants in residue form, which then stick to inside the windshield. 

3. A Leaking Heater Core 

A leaking heater core occurs more regularly than the other two possibilities. However, it is still something to keep in the back of your mind. This will leave a nasty, sliding film on the windshield that will be hard to get rid of and will be nearly impossible to see out of while driving. If you suspect your heating core is leaking, take your car in for a repair immediately!

The easiest and most effective way to get rid of haze on the inside of your windshield is to take some typical cleaning windshield products such as a streakless glass cleaner such as Invisible Glass (which is also ammonia-free) and a clean microfiber towel, or if you want help getting to the hard to reach places, use this Reach and Clean Tool These tools will give you the best, seamless, crystal clear finish on your windshield despite the condition it was in before. 

Another tool to get would be a windshield sunshade. This blocks the sun’s UV rays from penetrating through the window, which will keep the interior cool and prevent contaminants from seeping out and sticking to your windshield. 

How to remove road film residue from a car windshield?

If you drive at night, park under a tree, live in an area with hard water or drive in the rain, you probably will, if you haven’t already, experienced a grimy film coating the exterior of your windshield. The most frustrating thing is, it doesn’t matter how many times you run your windshield wipers and spray your wiper fluid, it won’t go away.

But, if you follow the guide we have to clean the windshield and use our recommendation for the Gtechniq G1 Clear Vision Smart Glass. This frustration will be a thing of the past and save you lots of time.

Windshield cleaning without streaks

1. Prepare the Solution

We recommend Stoner’s glass cleaner but you can make your own cleaner. Mix either 50% alcohol, 50% water, and a capful of white vinegar in a spray bottle or, mix 70% water, 15% window cleaner, 15% alcohol.

2. Wipe Down.

Use a clean microfiber towel to wipe down the surface such as these by The Rag Company, to make sure you have removed excess loose debris from the windshield. 

3. Spray the Solution.

The solution that you prepared in the spray bottle for Step 1 will aid in degreasing the windshield. Once you spray the white vinegar mixture on the inside glass, it will remove the sticky substances that are contributing to the haze. 

4. Apply a Streakless Cleaner

Use a streakless glass cleaner and either a clean microfiber towel or the reach and clean tool to wipe away all remnants of any hazy film. Make sure you spray the cleaner directly on the tool, which will help you avoid oversaturating the window. Use up and down motions to finish off the glass. 

5. Apply Rain Repellant (OUTSIDE ONLY)

Once your glass is clean, you can apply a product such as Gtechniq G1 Clear Vision Smart Glass, this product will improve visibility, haze, and assist in easier contaminants removal for ice, bugs and tree sap. For a good application, you will need to apply 3 coats.

Coat 1: Circular motions, 5-minute dry time

Coat 2: Sweeping horizontal motions, 5-minute dry time

Coat 3: Vertical lines, 15-minute dry time 


You may think that to clean a windshield wouldn’t involve much consideration and doesn’t involve much other than getting annoying smudges away from your line of sight. 

What we hope for you to understand through this post to cleaning windshields with haze, is if you take care in selecting the right process and following a proper regimen–you will never have to worry about hazy windshields causing low visibility again.
