Why It’s Important to Clean a Car Windshield
It is important to clean a windshield because it directly affects visibility. It is tied to driver’s safety and the lifespan of the glass and wipers. Rain, fog, night driving, or glare conditions can be dangerous if the glass is dirty. A clean and clear windshield makes roads, hazards, pedestrians, signals and traffic visible. Why clean windshield matters:
■ better visibility while driving
■ improved night driving
■ safer driving during rain
■ longer wiper blade life
Tool You Need Before Cleaning a Car Windshield

Recommended Tools
■ Microfiber glass towels: Best for streak-free wiping and final buffing.
■ Extendable windshield cleaning tool: for the inside glass; base of the windshield and tight corners.
■ Ammonia-free glass cleaner: for tinted windows and interior surfaces.

Window Film for Windshield Protection
Window film is a thin sheet that is made up of multi-layered plastic or PET. It blocks UV rays, reduces glare and gives you privacy. Window tints either absorb, reflect, or reject the solar energy which means that the incoming heat is reduced. The cabin and interiors stay cooler. One added advantage of window films is that it has self cleaning properties. Modern window tints come with hydrophobicity which makes them water repellent. And even dust does not rest. Window films make windshield cleaning easier.
Types of Window Film
You can choose from multiple options of window tinting available in the market. You should consider a few things before choosing window films. The IR rejection, UV rejection, and VLT. Also, do not forget to check if the film complies with CMVR rules.

How it works: There is a layer of dye between adhesive and protective coating.
■ Carbon Window Film
How it works: Present carbon particles block the solar heat.
■ Ceramic Window Film
How it works: Built with nano ceramic technology.
■ Metallic Window Film
How it works: Microscopic metal particles reflect heat and glare.
