Startnow 100 pieces/pack non-woven wide end cotton swab length 70 100 161mm anti-static industrial machine cleaning and dust-free wiping rod  

Dust-Free Non-Woven Swabs are used for cleaning optical lenses in laser cutting heads, welding heads, and other precision optical devices.
Material：
The swab tip is generally made of dust-free non-woven fabric, with fibers that are not easy to shed and will not scratch the lens coating.
The swab stick is usually made of PP or nylon material, offering sufficient hardness without damaging the lens edge.
Advantages
Lint-free: Leaves no fiber residue when cleaning optical lenses.
Anti-static: Some models are treated to prevent static electricity, reducing dust re-adsorption.
Strong adsorption: Effectively removes fine dust, oil stains, and fingerprints.
Applications
Cleaning protective lenses, collimating lenses, and focusing lenses of laser cutting heads.
Cleaning reflective lenses in fiber laser welding guns.
Routine maintenance of other precision optical devices (such as scanning mirrors, camera lenses, etc.).
How to Use
Typically used with anhydrous alcohol (IPA) or specialized lens cleaning solution.
Gently wipe the lens surface, avoiding repeated heavy rubbing.
Each swab is for single use only to prevent cross-contamination.
