Frequently Asked Questions

What qualifies as a "deep scratch" on a phone screen and can it be repaired by polishing?

A deep scratch is one that is clearly visible and can be felt with a fingernail. Polishing can reduce or eliminate deep scratches that are still within the glass surface layer. Scratches that have penetrated completely through the glass or caused structural damage cannot be repaired by polishing and require glass replacement.

How does deep scratch repair differ from standard screen polishing?

Deep scratch repair uses more aggressive polishing compounds (coarser grit) and longer polishing times compared to standard light scratch removal. Multiple polishing passes with progressively finer compounds may be needed to achieve a smooth, clear result without visible haze.

Is there a risk of making the screen thinner after deep scratch polishing?

Yes, deep scratch polishing removes more glass material than light polishing. While the amount removed is typically very small (a few microns), repeated deep polishing of the same screen can gradually thin the glass. Limit deep polishing to once per screen and replace the glass if deep scratches recur.

What polishing compound is recommended for deep phone screen scratch repair?

For deep scratches, start with a coarser aluminum oxide compound to remove the scratch, then follow with a finer cerium oxide compound to restore optical clarity and remove any haze left by the coarser compound. Always finish with a fine polish for the best visual result.
