How to Prevent Inside Windshield Haze?
Sunshade Cover for Interior
Especially if you park outside in the sun and face vinyl and plastic gas, a good windshield sunshade cover is a good idea. To keep your car cool and clean during the summer months.
Side Window Deflectors (Open Windows)
If you have a problem with a closed air filter, open one or two windows next to it to provide fresh air. Diversion windows go into the clutch here when you park your car outside. You can leave your car with the windows open until fresh air is provided, and at the same time, you are protected from the rain or snow that gets inside your car.
For Exterior
One of my favorite products to protect against windshield fog outside is Rain-X. It prevents the water from drying out and forms a small coat of hazard and also does a good job of making it difficult for other materials (such as pollen) to stick to the surface. If you install this product a fog will appear, which is normal. After it dries, pour in the water and clear the remaining mist. Do not use the product indoors.

Causes of Greasy Film & Cleaning Process of Windshield Haze
What Causes Haze on Inside of Windshield?
Clogged Cabin Air Filter
The exhausted air conditioning system reduced airflow due to a cabinet air filter that is a few years old and covered with dust.
What causes air temperature to rise gradually depends on how close the cabinet filter is, as well as other factors such as outdoor temperature and sun exposure. Not only does that cause fog car windows, but it also gives off a foul odor when HVAC is ON. Change your cabinet air filter regularly to avoid a dull air vent.
Heater Core Are Corrupted
Another possible and common problem is leaking from one of the connectors to the heater core. Once the heater is working, the air in the box will collect the coolant and install it on the windows through the front pipes, causing fog in the car windows and a foul smell from ethylene glycol (a natural compound used to prevent frost. Formation).
Often, you see a leak in the driver’s or passenger board, as the heater core is located somewhere under the dashboard, or in some cases, you see antifreeze under the car. At this point, the best advice I can give you is to visit a certified mechanic to ensure a leak and provide an adequate solution.
Vinyl Off-Gassing or Vinyl Protectors
Complete indoor ventilation such as vinyl seats, seat covers, the dash may evaporate and darken the inside of your windshield. Vinyl protection products sprayed on the vinyl itself may be the cause of the problem. Placing your car in the sun may improve the result.
Tips to Keep Clean Your Windshield from Haze or Greasy Film
Along with regular cleaning, there are a few preventative measures you can take to help keep your car’s front window clean and tidy. See below effective tips to prevent Windshield from Haze:
- Microfiber Clothing – You want to go directly to the microfiber fabric when choosing what to wipe your windshield. This type of fabric prevents strokes because it has very thin but soft fibers.
- Avoid Using Ammonia in Windows Tinted – Ammonia can damage the tint if applied directly to it. This is true even if you delete it immediately. Also, check your windshield cleaning formula if you plan to clean your windshield with tinting agents.
- Do Not Smoke in a Car – One of the major factors in the formation of fur on the windshield of your car is cigarette smoke. You will be able to see if this is a problem because the remnants of smoke will turn your towels yellow when you clean them from the air window.
- Use Windshield Sunshade – If you park in direct sunlight, consider getting a good windshield sunshade. This will keep your car as cool as possible in the summer and will prevent the rise of warm smoke from hitting your car’s front window.
- Avoid Abrasive Material – Even if your windshield is made of durable material, you can still scratch it if you clean it with an abrasive material. Paper towels, magic erasers, newspapers, or microfiber cloth are some of the acceptable materials that can be used as they are not old enough to cause scratches. Some strong clothing or products should be used with caution.
