ROYWOO Car Headlight Restoration Liquid 600ml (800g)

ROYWOO Car Headlight Restoration Liquid is a concentrated 600ml/800g polish that restores cloudy, yellowed, scratched, or hazed headlamp lenses to clear, near-new condition.

Over time plastic headlight lenses discolor, accumulate fine scratches, and develop haze that reduces light output and alters beam pattern. ROYWOO’s high-concentration restoration fluid is formulated to cut through oxidation, dissolve embedded grime, and smooth surface imperfections so headlights become clearer and brighter without costly replacement. The formula comes in a dark-blue liquid with child safety and leak-proof caps for safer storage and handling.

How does ROYWOO restore heavily yellowed or cloudy headlights?

The liquid contains powerful polishing agents designed to remove the oxidized layer on polycarbonate lenses and lift discoloration. Applied with light mechanical action, it evens the surface and reveals the clear plastic beneath, improving clarity and light transmission.

• High-concentration dark-blue formula for stronger cleaning action
• Works with manual polishing pads or rotary polishers
• Removes oxidation, surface stains and light yellowing in one treatment
• Includes leak-proof inner cap and anti-theft outer cap for secure storage

Can it fix scratches and small cracks on headlamp lenses?

For fine to moderate surface scratches, ROYWOO’s restoration fluid polishes and fills shallow abrasions, making them much less visible and smoothing the lens. Deep gouges or structural cracks may require replacement, but the product can improve appearance and reduce glare from minor damage.

• Reduces visibility of light-to-moderate scratches
• Polishing action smooths micro-abrasions to restore optical clarity
• Not a structural repair for deep cracks—cosmetic improvement only
• Suitable for multiple treatment passes for better results

How do I use the ROYWOO headlight repair liquid safely and effectively?

Use in a shaded area, wearing gloves and eye protection. Apply a small amount to a clean pad or cloth, work across the lens with consistent pressure, then remove residues and inspect; repeat if needed for stubborn haze.

• Store in original bottle; keep out of sunlight and away from children and pregnant women
• Do not open near valuables; flush eyes with water and seek medical help if contacted
• Compatible with manual or machine polishing—adjust speed/pressure appropriately
• Finish with a clean microfiber cloth to remove polish residue and check clarity
