Why Plexus Is Safer Than Glass Cleaner for Aircraft

Aircraft windshields are not made of glass. Most modern aircraft use acrylic, polycarbonate, or stretched acrylic for their windshields and side windows. These materials are fundamentally different from automotive glass and require specialized care.

The Danger of Standard Glass Cleaners

Most household and automotive glass cleaners contain ammonia, alcohol, or other solvents. On aircraft acrylic windows, these chemicals can:

• Cause crazing — a network of fine cracks that develops over time, reducing visibility and structural integrity
• Cloud the surface — creating a hazy, milky appearance that worsens with each application
• Weaken the material — making the windshield more susceptible to stress fractures
• Strip protective coatings — removing UV-protective layers applied by the manufacturer

Why Plexus Is the Industry Standard

Plexus was specifically formulated for plastics and acrylics. It works by:

1. Cleaning without solvents — uses a non-abrasive, non-ammonia formula that lifts contaminants without attacking the substrate
2. Filling micro-scratches — contains optical-grade fillers that smooth minor surface imperfections
3. Leaving a protective layer — creates an anti-static barrier that repels dust and reduces future contamination
4. UV protection — helps maintain the factory UV-protective properties of the windshield

Proper Application Technique

For best results on aircraft windshields:

• Apply Plexus with a clean, soft microfiber cloth
• Work in straight lines, never circular motions (circular motions create swirl marks on acrylics)
• Use light pressure — let the product do the work
• Buff with a separate clean microfiber cloth
• Never clean a dry windshield — always use Plexus or distilled water first

The Bottom Line

Using a $5 glass cleaner on a windshield that costs $5,000 to $50,000 to replace is not a risk worth taking. Plexus costs a few dollars more and is specifically designed to protect your investment.

At SkyShine Aircraft Detailing, Plexus is the only product we use on aircraft windshields and windows. No exceptions.
