Miertech Deep Scratch Repair Solution
Deep Scratch Remover / Grinding Machine for iPhone Screen Repair
Miertech Deep Scratch Remover, also called a grinding machine, is designed for severe iPhone screen scratches that ordinary polishing cannot handle. It can complete the deep scratch grinding step in as little as 3 minutes, then the phone is sent to the Miertech polishing machine for about 30 minutes to restore clarity and a like-new appearance. For phone refurbishment businesses, this workflow can help upgrade poor-condition Grade D screens toward a Grade A appearance.

Deep Scratch Removal

Place the phone in the Miertech Deep Scratch Remover / Grinding Machine. The machine uses precision grinding technology to remove deep scratches and severe surface damage in as little as 3 minutes.
Deep scratches are removed quickly, but the screen surface becomes matte and may show fine grinding marks.
After Grinding

After the 3-minute grinding step, the screen surface will become frosted and the gloss is reduced. This is a normal result of the grinding process.
Deep scratches are eliminated, but the screen temporarily loses gloss and looks frosted.
Polishing & Restoration

Send the phone to the Miertech phone polishing machine for about 30 minutes. The polishing process restores clarity, smoothness and the original visual experience.
The screen becomes bright and clear again, with excellent clarity and a like-new appearance.
