How DeScratch Works: Step-by-Step Scratch Repair for Devices

DeScratch: The Complete Guide to Fixing Scratched Screens

What DeScratch is

DeScratch is a step-by-step method and set of techniques for reducing or removing surface scratches from glass, plastic, and device screens using consumer-grade tools and compounds. It focuses on assessing scratch depth, selecting the right materials, and using controlled polishing to restore appearance without damaging coatings.

When to use it

• Light surface scratches: hairline marks and scuffs on glass or plastic.
• Shallow plastic scratches: on acrylic phone cases, watch crystals, or camera housings.
• When screen coatings are intact: if anti-reflective or oleophobic coatings are damaged, full replacement may be better.

What you need

• Assessment tools: bright light and magnifier.
• Cleaning supplies: microfiber cloth, isopropyl alcohol.
• Abrasives/polishes: polyurethane or cerium oxide for glass, plastic polish (e.g., Novus), fine-grit sandpaper (2000–5000) only for plastics.
• Polishing tools: felt pads, soft cloths, rotary tool with low RPM (optional).
• Protective gear: gloves, eye protection.

Step-by-step (prescriptive)

1. Inspect: Use bright light and magnifier to judge scratch depth.
2. Clean: Wipe the area with isopropyl alcohol and a microfiber cloth.
3. Test spot: Try procedure on a small inconspicuous area or spare piece.
4. Light polishing (for very fine scratches): Apply plastic polish or cerium oxide with a microfiber or felt pad in circular motions for 30–60 seconds; wipe and inspect.
5. Moderate scratches (plastic): Wet-sand with very fine grit (start 2000), keep surface wet, sand lightly in straight strokes, switch to 3000–5000 grit to remove sanding marks, then polish.
6. Deep scratches: Consider professional repair or screen replacement; repeated aggressive polishing risks damaging coatings or changing light transmission.
7. Finish: Clean residue, optionally apply a screen protector to hide remaining marks and protect surface.

Risks and limitations

• Coating damage: polishing can remove anti-reflective or oleophobic coatings.
• Optical changes: over-polishing may create cloudiness or uneven gloss.
• Not always permanent: deep scratches usually require replacement.

Maintenance tips

• Use a tempered glass screen protector to prevent future scratches.
• Clean with microfiber and mild cleaner; avoid abrasive cloths.
• Keep devices in cases when not in use.

Quick decision guide

• Hairline scratch: Try DeScratch polishing.
• Visible gouge or cracked glass: Replace the screen.
• Coating already worn: Replace to restore original feel and clarity.
