Quick Answer: Most monitor scratches can’t actually be fixed — they’re gouges in the factory anti-glare coating, and display-repair consensus is there’s no reliable way to polish that coating back to new without spreading the damage into a bigger, shinier patch. What you can do is confirm it’s really a scratch and not a wipeable scuff (a 30-second cloth-and-water test), check whether it’s deep enough to catch a fingernail (if so, it’s permanent), and add a screen protector going forward so the next mark lands on replaceable film instead of the panel itself.
Search “monitor scratch repair” and most of what comes back is generic phone- and headlight-scratch advice — toothpaste, baking soda, fine sandpaper and polish. Those methods target bare, uncoated plastic or glass. A 2026 monitor almost never has bare plastic on top; it has a manufactured anti-glare or anti-reflective coating, and that coating is what most of this advice quietly ruins instead of fixes.
Step 1: confirm it’s actually a scratch
Power the monitor off. Wipe the mark with a dry microfiber cloth, then a cloth lightly dampened with distilled water — never spray liquid directly onto the glass. A lot of what looks like a scratch is really a scuff: material sitting on top of the coating (dust, a fingerprint, dried cleaning residue) rather than gouged into it, and it partially or fully lifts off with this test. A true scratch doesn’t move no matter how you wipe it.
This costs nothing and takes under a minute, and it’s the single most skipped step before people move on to polish, toothpaste, or a replacement panel they didn’t actually need.
Step 2: why phone- and headlight-scratch tricks don’t work here
Most modern monitors carry a factory anti-glare coating rated by haze percentage — a light coating runs roughly 13-18% haze, a heavier one 25%+ — a deliberately textured microstructure, not a flat painted surface. Polishing compounds are built to smooth and re-shine bare acrylic or glass; run one over a hazed coating and it doesn’t restore that texture, it strips it, leaving a shinier or duller patch that’s more visible than the original scratch.
This isn’t a guess: Novus’s own product documentation for its #2 and #3 Plastic Polish formulas — the versions actually marketed for scratch removal — states they aren’t recommended for coated or UV-protected plastic surfaces, which describes a monitor’s anti-glare layer exactly. Novus 1 Cleaner is labeled safe for LCD/LED screens, but the company’s own notes warn it leaves a shiny glaze behind, which looks worse, not better, on a matte panel. Toothpaste and baking-soda pastes have no coating-aware formulation at all — they’re mild abrasives meant for headlight lenses and eyeglass frames, not a display’s engineered surface.
There’s one narrow exception: a bare glossy panel with no coating, or a scratched tempered-glass overlay sitting on top of the actual screen. That’s uncommon on new monitors but does show up on older TN-panel displays and some glossy all-in-ones. Even there, a light polish only has a real chance on shallow, hairline marks — not on anything that catches a fingernail.
| What you see | Likely diagnosis | What to do |
|---|---|---|
| Mark lifts off with a dry or barely-damp microfiber cloth | Scuff or smudge, not a scratch | Nothing further needed — clean and done |
| Mark stays after cloth test, doesn't catch a fingernail | Shallow coating scratch | Leave it, or add a screen protector to visually soften it |
| Mark catches or snags a fingernail | Deep gouge into the coating or panel | Permanent — no polish or DIY fix will remove it |
| Panel has no matte texture (glossy/TN or tempered glass) | Rare case with no factory anti-glare coating | A light polish has a small chance on hairline marks only |
| New scratches keep appearing over time | Grit transfer from a shared cleaning cloth or desk debris | Dedicate one cloth to the monitor and add a screen protector |
WHOOSH! Screen Shine Pro
- An alcohol- and ammonia-free screen cleaner is the safer version of the "cloth and water" test from Step 1 — it won't strip the coating the way a household glass cleaner can if you get heavy- handed with it.
- See our full best monitor cleaning kit guide for the complete lineup and a budget microfiber-only option.
KEANBOLL Anti Blue Light Screen Protector Panel
- A rigid acrylic panel sits a few millimeters off the glass on tabs, so contact from a pen, a fidgeting finger, or a curious pet lands on replaceable acrylic instead of the coating underneath.

Monitor scratches, by the numbers
- 13-18% vs. 25%+ haze. The haze percentage behind a “matte” or anti-glare finish — a textured microstructure bonded to the panel, not a flat coat of paint, which is exactly why a generic plastic polish can’t smooth it back to new the way it would a scratched headlight lens.
- 0 recommended for coated plastic. Novus’s own product documentation excludes its #2 and #3 Plastic Polish — the formulas marketed for scratch removal — from use on coated or UV-protected plastic surfaces, the same category a monitor’s anti-glare layer falls into.
The bottom line
Before reaching for polish, toothpaste, or a repair kit built for phone screens and headlights, spend 30 seconds on the cloth-and-water test — a large share of “scratches” turn out to be scuffs that wipe away completely. If it’s a real scratch, the fingernail test tells you whether it’s worth worrying about: shallow marks that don’t catch a nail can be left alone or masked with a screen protector, while anything that does catch is permanent, and no polish marketed for bare plastic will fix a factory anti-glare coating without making the spot worse. Once it’s resolved one way or the other, a rigid screen protector is the cheapest way to make sure the next scratch lands on something replaceable instead of the panel itself.
