Restore your phone’s middle frame and shield covers to like-new condition with the LANRUI Jade Gourd 30ml Middle Frame Repair Liquid. This professional-grade cleaning and repair solution is specially formulated for mobile phone technicians to quickly remove stubborn grease, oil stains, alcohol marks, discoloration, yellowing, blackening, and copper oxidation from motherboard frames, shield cages, and covers.

The fast-volatile formula dissolves stains and oxidation in seconds, then evaporates cleanly with minimal residue (best results when followed by board washing water or isopropyl alcohol). Its anti-corrosion and anti-static properties make it safe for sensitive components, while the distinctive jade gourd-shaped bottle with dual-cap anti-leak design ensures easy, spill-free use in the workshop.

Perfect for aesthetic restoration and professional repair work on iPhone, Android, and other devices — one drop is often enough to restore original copper color and gloss.
