McKee's 37 Clear Plastic Cleaner & Restorer for Vinyl Windows — Removes Yellowing, Anti-Haze Finish

McKee's 37 Clear Plastic Cleaner & Restorer is a polish that cleans, removes yellowing, and restores clarity to clear vinyl and plastic windows without leaving haze.

Over time clear vinyl windows and plastic windscreens pick up UV damage, airborne grime, and micro-scratches that cloud visibility and age the vehicle. McKee's 37 combines ultra-refined abrasives with specialized cleaners to lift oxidation and surface contaminants while polishing the plastic back to a transparent finish. It’s formulated for the soft nature of clear vinyl so it restores clarity without abrading too aggressively or dulling the surface finish.

How does McKee's 37 remove yellowing and haze from clear vinyl windows?

The formula uses fine abrasives and cleaning agents that loosen embedded pollutants and lightly abrade the top oxidized layer. As the old, discolored surface is polished away, the product simultaneously buffs the plastic to a uniform, transparent look rather than leaving uneven patches.

• Ultra-refined abrasives lift oxidation and micro-scratches
• Surfactants dissolve airborne grease and film
• Polishing action produces a clear, streak-free finish

What surfaces and vehicles can I use this restorer on?

McKee's 37 is designed for any clear plastic or vinyl that needs clarity restoration. It’s commonly used on convertible top windows, boat windows, motorcycle windscreens, instrument clusters, and vehicle headlight lenses made from compatible plastics.

• Convertible and Jeep soft-top clear vinyl windows
• Clear vinyl boat windows and marine curtains
• Motorcycle windscreens and headlight lenses
• Interior clear plastics like instrument clusters

How should I apply the cleaner for the best, longest-lasting results?

Start with a clean, dry surface and work in small sections using a soft cloth or foam applicator. Rub the product into the vinyl using moderate pressure, then buff off residues to reveal clarity; repeat for deeper oxidation and finish with a gentle wipe to remove any polish haze.

• Clean surface of loose dirt and salt first
• Apply with soft cloth or foam pad in circular motions
• Buff until clear, repeating for heavy discoloration

Will this product damage my soft-top or cause clouding after use?

McKee's 37 is formulated for clear vinyl and compatible plastics, balancing cleaning strength with gentle abrasives to avoid excessive thinning. When used as directed—small sections and light to moderate pressure—it restores clarity rather than leaving dull or hazy spots; always test a hidden area first for sensitive materials.

• Safe for most clear vinyl when used correctly
• Avoid aggressive pressure or abrasive tools on thin plastics
• Spot-test on a concealed area before full application
