Whether you’re managing a cleanroom, a high-end detailing shop, or just someone who is very serious about streak-free mirrors, a 400-piece bulk pack of high-efficiency lint-free cloths is a staple.

Since “High-Efficiency” usually refers to Class 100 (ISO 5) or Class 1000 (ISO 6) industrial standards, these are typically composed of continuous filament polyester or a cellulose-polyester blend.

Key Technical Highlights

• Non-Abrasive Texture: Designed to clean sensitive surfaces (optical lenses, semiconductor wafers, or touchscreens) without micro-scratching.

• Minimal Extractables: These cloths are laundered in ultra-pure water and vacuum-packed to ensure they don’t leave chemical residues or metallic ions behind.

• Durability: Unlike paper-based wipes, these won’t degrade or “pill” when saturated with cleaning agents.

Common Applications

• Electronics: Cleaning PCB components and LCD screens.

• Laboratory: Wiping down glassware and sensitive instruments.

• Automotive: Final wipe-down for ceramic coating application or instrument clusters.

• Printing: Cleaning delicate print heads and rollers.
