In ESD-controlled work zones, wiping is never “just cleaning.” A wipe can either remove contamination or redistribute it via static attraction, edge shedding, or solvent drag marks. The VISION 50 ESD 12" x 12" wiper is positioned for ISO Class 5 (Class 100) wipe-down where teams want a heavy-weight polyester knit that’s anti-static, cleanroom laundered, and packaged with lot traceability. It’s designed to reduce variability between operators: one wipe, one fold pattern, one direction of travel—repeatable across shifts.

• Bench and work-surface wipe-down in static-sensitive assembly, inspection, and packaging areas.
• Tooling and fixture wipe-down where particulates and light residue can drive yield loss.
• Final wipe before cover/close-out (lids, totes, trays, and protected work cells).
• Solvent-compatible wipe-down where teams want a durable knit that stays intact under moderate abrasion.
• Controlled “touch points” (glove contact areas, handles, doors, carts) where static and residue can build up quickly.

• ESD / anti-static knit construction: carbon core nylon fibers are described as continuously filamented throughout the knit for static-control intent.
• Heavy-weight feel (140 gsm): supports wipe pressure without “flimsy wipe” skipping or early saturation break-through.
• Cleanroom laundering and packaging discipline: described as laundered using ultra-filtered water and HEPA-filtered air drying, with sealed packaging and lot traceability.
• Double-bagged and vacuum packed: helps reduce bag-borne contamination transfer into the gowning area or wipe station.
• Low-linting intent (not “lint-free”): no wiper is truly lint-free—what matters is controlled fiber release and consistent handling technique.

VISION 50 ESD is described as a polyester knit made from premium quality virgin polyester fibers with carbon core nylon fibers continuously filamented through a no-run knit construction. The wiper is described as cleanroom laundered and individually inspected with lot-to-lot traceability. Edges are described as knife-cut, which is a practical tradeoff: it can be a cost-effective knit option, but operators should treat edges as the “highest-risk zone” for fiber transfer if they scrub aggressively or wipe rough surfaces.

These are the operational specs that typically drive whether a 12" x 12" ESD wipe behaves consistently at the wipe station (folding, wet-out, drag feel, and wipe coverage).

Cleanliness metrics are most useful when your QA team ties them to a specific method (extraction conditions, solvent, and reporting units). For this SKU, SOSCleanroom and the primary manufacturer product page emphasize low extractables, but do not publish SKU-level ionic extractables and NVR values in the sources listed below. Tables are included to keep qualification structured.

Ion	Typical value	Notes
Sodium (Na+)	Not published	Not stated in source basis
Chloride (Cl-)	Not published	Not stated in source basis
Potassium (K+)	Not published	Not stated in source basis
Calcium (Ca2+)	Not published	Not stated in source basis

• Packaging (SOSCleanroom): 100 wipes per bag; 10 bags per case (1,000 wipes/case).
• Packaging (manufacturer description): double bagged and vacuum cleanroom packed; also described as hermetically sealed in cleanroom-cleaned packaging under class 10 air-stream.
• Sterility: Non-sterile (dry).
• Traceability: described as individually inspected with lot-to-lot traceability (ISO 9000 referenced by manufacturer description).
• Country of origin (manufacturer statement): Malaysia (listed on Hospeco Brands catalog page for VS50-1212).

The best wipe can still fail if technique is inconsistent. For ISO-class wipe-down, the goal is controlled removal: trap contamination in the wipe, avoid redepositing it, and keep the “dirty edge” from contacting cleaned surfaces.

• Fold discipline: fold into quarters to create eight clean faces. Rotate faces on a timer or by area coverage—do not “chase” a streak with the same face.
• Direction control: wipe in one direction (top-to-bottom or back-to-front). Avoid circular “polishing” that can redeposit particles.
• Edge awareness: treat knife-cut edges as higher-risk; keep edges off critical optical/electrical contact surfaces when possible, and avoid aggressive scrubbing on rough fixtures.
• Wet-out consistency (if using solvent): use measured dispense (by stroke count or mL) so “too dry” doesn’t drag and “too wet” doesn’t flood seams or fasteners.
• Pressure control: moderate, even pressure is better than heavy force. High force can increase fiber release and can drive contamination into surface texture.
• ESD workflow: keep wipes stored in the controlled area packaging until point-of-use; avoid staging open wipes near fans or high-airflow returns.
• Stop rules: if the wipe face shows visible loading, streaking, or snagging—switch faces or replace the wipe immediately.

• “Wipe looks clean” fallacy: operators reuse the same face too long, turning a cleaning action into a redistribution action.
• Edge shedding on rough hardware: knife-cut edges can snag on burrs, threads, or sharp corners—prep surfaces or change technique if snagging occurs.
• Over-wetting: excess solvent can carry contaminants into seams, labels, and under fasteners—especially on benches with lap joints.
• Under-wetting: a too-dry wipe increases drag and can leave haze or streaking from uneven contact pressure.
• Packaging breaches at the station: leaving bags open invites airborne loading before use—open, remove, reseal.

If you’re standardizing an ESD wipe family, these are common cross-shops based on ISO class target, size, and ESD intent:

• ULTIMATE 5 ESD Cleanroom 12" x 12" Wiper (ISO Class 3–4): typically considered when teams want a tighter ISO class target in an ESD wipe.
• VISION 1 PINK ESD Cleanroom 12" x 12" Wiper (ISO Class 6): typically considered when the environment target is less stringent but ESD handling is still required.
• VISION 50 ESD 9" x 9" (ISO Class 5): same family behavior in a smaller format for tighter access or smaller wipe zones.

VISION 50 ESD is positioned for ISO Class 5 (Class 100) use and is also listed across ISO Class 5–8. In practical terms, it’s a strong fit when you need: (1) durable knit contact, (2) ESD / anti-static intent, and (3) packaging/traceability discipline that supports receiving inspection and lot control. For wipe stations, this product also supports standardization: consistent size, consistent fold geometry, consistent wipe coverage.
