Description
Weston Disposable Cleanroom Wipes are 100% continuous-filament polyester wipes built for low-particle cleaning in electronics, optics, and lab environments.
Core Features
1. Near-Zero Particle & Fiber Release
Made from 100% continuous-filament polyester - not chopped staple fiber - so there are no loose fiber ends to shed, even under repeated, aggressive wiping.
2. Soft, Non-Scratch Surface
Gentle enough for anti-reflective coatings, polished glass, and finished metal that mark easily under abrasive wipers.
3. A Sealed Edge for Every Particle Budget
Choose cold-cut, laser-sealed, or ultrasonic-sealed edges depending on how strict your particle-count requirement is. Sealed options bond the border fibers so nothing works loose at the seam.
4. Steady Wet & Dry Performance
Holds its strength when pre-saturated with IPA, deionized water, or other common cleanroom solvents - no swelling, tearing, or residue transfer back onto the surface.
5. Contamination-Controlled Packaging
Double-bag vacuum sealing keeps particles out until the wipes are needed: strip the outer bag at the gowning station, and only the inner, pre-clean bag crosses into the classified space.

Application Scenarios
Four common environments, and the configuration that tends to perform best in each:
Semiconductor & Electronics Assembly
On a PCB assembly line, flux residue has to come off board surfaces before reflow inspection, and wafer-handling fixtures need the same treatment between runs. Best fit: 9"×9" Ultra-fine, ultrasonic-sealed edge, pre-saturated with IPA. Why it works: continuous-filament construction leaves no loose fiber to bridge two contact points, and the ultrasonic edge keeps particle generation lowest right where exposed circuitry is most sensitive.
01
Precision Optics & Lens Manufacturing
A freshly coated AR lens or polished mirror won't tolerate a wipe with even one loose thread - a single stray fiber can scratch a coating that took hours to apply. Best fit: 4"×4" or 6"×6" Ultra-fine, laser-sealed edge, used dry or lightly dampened, in a single directional stroke. Why it works: finer filaments mean more surface contact per stroke, and the laser-sealed edge guarantees nothing comes loose against the coating.
02
Medical Device & Pharmaceutical Cleanrooms
Batch changeovers inside an ISO-classified assembly cell are exactly when particle counts tend to spike, as fixtures and work surfaces get wiped down between runs. Best fit: Superfine grade, double-bag vacuum packaging. Why it works: the outer bag gets stripped off in the gowning room, so only the inner, pre-clean bag ever crosses into the classified space - keeping the changeover from becoming a contamination event.
03
Laboratory & Analytical Instrument Care
A microscope objective or spectrometer housing only needs to pick up one stray fiber to throw off a reading. Best fit: Standard grade, cold-cut or laser-sealed edge, dampened with deionized water or IPA. Why it works: everyday bench surfaces don't need the finest - and most expensive - grade, so Standard balances absorbency and cost for routine cleaning.

FAQ
Q: What's the real difference between Standard, Superfine, and Ultra-fine - which one do I need?
A: The grades differ in filament fineness, not in base material. Finer filaments pack more fiber surface into the same wipe area, so they pick up smaller particles and hold more liquid per stroke. Standard suits general bench cleanup; Superfine covers most in-process cleanroom wiping; Ultra-fine is worth the extra cost only where a handful of stray particles actually matters - optics, wafer handling, sealed assemblies.
Q: Can I use these wet, or do they need to be pre-saturated?
A: Both. Use them dry for general dusting, or pre-saturate with IPA, deionized water, or another common cleanroom solvent for solvent-wipe steps. Since the fiber is 100% polyester, it doesn't swell or lose strength when wet, so a saturated wipe performs close to a dry one.
Q: How do I choose between cold-cut, laser-sealed, and ultrasonic-sealed edges?
A: Cold-cut is the most economical and fine for lower-classification areas. Laser-sealed fuses the border fibers and cuts down on loose edge lint at a moderate cost step-up. Ultrasonic-sealed fully bonds the edge and generates the fewest particles at the seam - the usual choice for the most contamination-sensitive steps.
Q:What cleanroom classification are these wipes suitable for?
A: It depends on grade and edge finish. Ultrasonic-sealed Ultra-fine wipes are typically specified for higher classifications - roughly ISO Class 5–6 (comparable to the older Federal Standard 209E "Class 100–1,000" designations) - while cold-cut Standard wipes are more commonly used in ISO Class 7–8 areas. Match the exact classification against the batch COA rather than the grade name alone.
Q: How should I store and handle the wipes to protect particle counts?
A: Keep sealed bags in a clean, dry area out of direct sunlight. Bring a bag into the cleanroom through the gowning or airlock area, strip the outer bag there, and don't open the inner bag until you're inside the classified space. Handle the stack with gloves rather than bare hands.
Q:Can Weston provide custom sizes or private-label packaging?
A: Custom cutting, folding patterns, and private-label bag printing are available for qualifying order volumes - share your target size, grade, and edge finish with our sales team for a quote.
