Primary Applications

1. Camera Module Cleaning: Removes dust motes, fingerprints, and smudges from exposed camera lenses before closing up a phone.
2. Sensor & Prism Cleaning: Cleans Face ID dot projectors, infrared sensors, and periscope zoom prisms where liquid cleaners could cause moisture damage or optical clouding.
3. Display & Glass Optics: Safely cleans small internal glass elements and optical sensors without scratching delicate Anti-Reflective (AR) coatings.

Usage Tips

1. Dab, Don't Rub: Gently press the gel tip straight down onto the dust particle or lens area and pull straight up. Avoid wiping or dragging it forcefully across the glass.
2. Keep Sealed: Keep unused sticks inside their sealed package to prevent ambient dust from ruining the gel's natural adhesion.
3. No Solvents: Use dry—do not dip the gel tip in Isopropyl Alcohol (IPA) or liquid cleaners, as this can break down the synthetic resin material.
