CARPRO CeriGlass Glass Polish & Cleaner 500ml — Restores Clarity, Removes Light Scratches & Water Spots

CARPRO CeriGlass is a professional-grade glass polish and cleaner compound that restores automotive glass to near-original clarity by removing swirls, light scratches, water spots, and wiper marks.

If your vehicle glass looks dull, hazy, or has fine abrasions from wiper contact and environmental grit, CeriGlass is formulated to cut through those defects without the visual distortion common to older cerium oxide products. Developed for use with rotary polishers and effective with dual-action machines, this 500ml (17oz) bottle provides enough product to address windshields, side glass, and back glass on most cars and light trucks.

How does CeriGlass improve visibility on a daily-driven windshield?

CeriGlass works by physically polishing the glass surface to remove light scratches, shallow pits, and swirl marks that scatter light and create haze. The formula is aggressive enough to make a visible improvement yet controlled to avoid introducing optical distortion when used properly.

• Removes wiper-induced scratches and sand-grit abrasions
• Diminishes water spots and fine etching from minerals
• Leaves a smooth surface for clearer night and rainy-condition vision

Can I use this with both rotary and dual-action polishers?

Yes — CeriGlass is designed for rotary polishers for maximum cutting power but also performs well with dual-action machines for lighter defect removal and safer use. Machine choice depends on the severity of the defects and your comfort level with polishing tools.

• Rotary: best for deeper swirls and light scratches
• Dual-action: effective for water spots and fine shallow swirls
• Use appropriate polishing pads and speeds to avoid overheating

Will this product cause optical distortion like traditional cerium oxide?

CeriGlass has been formulated to avoid the visual waviness or distortion sometimes associated with older glass compounds. When applied correctly, it polishes away defects while preserving the glass’s optical clarity.

• Non-distorting formula compared to many cerium oxide compounds
• Test a small area first to confirm desired finish
• Finish with a light polish pass for best optical results

What surfaces and defect types is it best suited for?

This compound focuses on automotive glass: windshields, side windows, rear glass and mirrors. It’s excellent for swirls, light scratches, wiper marks and shallow pits; deeper cracks or chips require windshield replacement or professional repair.

• Ideal for wiper scratches, sanding grit marks, and light etching
• Use on laminated and tempered automotive glass surfaces
• Not intended to repair deep cracks or structural damage

Who is this for: CARPRO CeriGlass is intended for enthusiasts, detailing professionals, and DIYers who want to restore automotive glass clarity without introducing optical distortion. Choose CeriGlass if you have visible light scratches, water spots, or wiper marks and you are comfortable using a polisher or following careful hand-polishing techniques. For severe damage or structural chips, consult a windshield repair specialist before polishing.
