STX1004 Sterile AlphaWipe 4" x 4" 100% Polyester Cleanroom Wiper

STX1004 Sterile AlphaWipe is a low-linting in context (no wiper is truly ‘zero-lint’ in every process condition), high-absorbency knitted polyester wiper used for sterile wiping, spill control, and solution application/removal in controlled environments. It is constructed from 100% continuous-filament polyester in a double-knit, no-run interlock pattern for durability on equipment, fixtures, and rougher surfaces. STX1004 has a laundered cut edge and is designed so the wiper will not easily snag or abrade, helping reduce particle/fiber contribution during rigorous wipe-downs.

Sterility note: STX1004 is gamma-irradiated and sterile validated to a Sterility Assurance Level (SAL) of 10⁻⁶ (AAMI guideline framework) and is tested for endotoxins. Sterile dry shelf life is 3 years from date of manufacture.

About the Manufacturer:

Texwipe (an ITW company) differentiates itself in cleanroom wiping by treating the wiper as an engineered product, not a commodity consumable. Its manufacturing approach starts with fabric and yarn selection, then controls edge construction, controlled cleaning/laundering, and packaging aligned to cleanroom application tiers. For sterile programs, Texwipe positions gamma irradiation validation (SAL 10⁻⁶) and case-level documentation discipline (including certificates of compliance/analysis/irradiation) as part of the sterility and traceability model.

SOSCleanroom (SOS) supports that manufacturing discipline with a close working relationship with Texwipe focused on continuity of supply, clean documentation handoff (certs, lot traceability), and practical application support—so customers can standardize sterile wiping materials with predictable performance while maintaining procurement reliability and audit readiness.

Common Applications:

Wiping and cleaning surfaces, equipment and parts
Spill control
Applying and removing lubricants, adhesives, residues and other solutions including disinfectants
Cleaning with solvents such as isopropyl alcohol (IPA), acetone, and degreasers (verify compatibility to your SOP)
Cleaning and polishing stainless steel
Protective covering for parts and product; lining trays for holding, protecting, drying and storing of parts, equipment and devices

Best-Practice Use:

Open aseptically: Stage the outer case outside your clean zone and open inner packaging per your facility entry rules to protect sterility.
Fold for control: Fold into quarters to create multiple clean faces; rotate faces instead of re-wiping with a loaded surface.
Wipe pattern: Use straight-line, overlapping strokes (top-to-bottom or left-to-right) to avoid re-depositing contamination.
Charge deliberately (if wet wiping): If adding solvent/disinfectant at point-of-use, dampen—do not over-saturate—to maintain control and reduce run-off.
Change-out triggers: Replace the wiper when the face becomes visibly soiled, tacky, or starts leaving streaks/residue.
Small-format discipline: Treat 4" x 4" wipes as precision tools—one surface zone per face—to reduce cross-contamination.

Selection Notes (STX1004 vs. Other Options)

STX1004 vs. TX1004 (non-sterile): Same AlphaWipe knit polyester platform, but STX1004 adds sterile presentation (gamma irradiation validation framework) and sterile-program shelf-life/documentation expectations.
STX1004 vs. TX3211 (SterileWipe® LP): Choose STX1004 for small-format precision work and tight access; choose larger sterile formats when coverage per wipe matters and change-out discipline is standardized.
Cut edge vs. sealed edge/border: If edge-derived fibers are the limiting risk in your contamination budget, validate the step and consider sterile sealed-edge or sealed-border alternatives for that specific operation.

ISO 14644 Operations Control Texwipe AlphaWipe® (Sterile) Polyester / Low Particulate Sterile Detail Wiping & Small-Area Cleaning 4" x 4" Lot Traceability

Texwipe STX1004 Sterile AlphaWipe® 4" x 4" Polyester Cleanroom Wiper — sterile small-format wiping for confined areas and controlled surface touchpoints

Texwipe STX1004 Sterile AlphaWipe® is a sterile polyester cleanroom wiper in a compact 4" x 4" format, commonly selected for detail wiping and small-area cleaning where full-size wipes are impractical or increase the risk of uncontrolled contact. Small-format wipes are frequently used to support controlled handling in tight spaces, around ports, fixtures, and equipment features where the cleaning area is limited and the technique must remain repeatable. Polyester wipe platforms are often selected when facilities need a consistent wipe method and controlled residue management per SOP. As with all sterile wipes, performance depends on controlled introduction, one-pass/one-face technique, and defined change-out triggers. Final suitability should be confirmed against current manufacturer documentation and your internal limits for residues, ions, and surface quality.

Operations takeaway: STX1004 supports ISO-aligned operations control by enabling a more controlled contact footprint for small-area wipe-downs. Standardize fold/face usage, define wetness targets, and use strict change-out triggers to prevent re-deposition in critical zones.

ISO-first context: where wipers fit in cleanroom operations control

ISO 14644-5:2025 frames cleanroom performance around a documented Operations Control Programme (OCP) that governs personnel practices, material transfer, cleaning, maintenance, and monitoring. Wipers belong in that system because the wipe itself, the chemistry, and the technique directly affect residues, particles, and recontamination risk. If you clean parts, fixtures, tools, or work surfaces inside an ISO-class controlled environment, the method should be written, trained, and repeatable.

Control point: Most “wiper failures” are technique failures—over-wetting, re-wiping with a loaded face, backtracking into clean areas, or using a wiper beyond its change-out point.

What this wiper is designed to do (typical use cases)

Sterile detail wiping of small surfaces and controlled touchpoints where a full-size wipe increases the risk of unintended contact.
Damp-film wiping using facility-approved sterile solvents/chemistries where the SOP defines wetness target and contact method (no pooling/dripping).
Cleaning around ports, fittings, hinges, and interface areas where controlled contact footprint improves repeatability.
Tool and fixture wipe-downs where compact wipe size supports better fold/face control during use.
Spot cleaning and finishing passes when surface quality and residue control depend on disciplined one-pass/one-face technique.

Method note: Small wipes can reduce accidental contact, but they can also drive higher change-out frequency. Define discard triggers clearly and keep wipe usage tied to zone boundaries. For confined geometries beyond the wipe’s control, define the swab method separately (one swab, one area; no re-dipping).

Best-practice use (reduce residues, particles, and rework)

Control introduction: bring wipes into the cleanroom per your OCP rules (outer packaging removal, staging, and storage).
Use clean-to-less-clean flow: wipe from the cleanest zone to the dirtiest zone; do not backtrack.
Fold for control: fold to create multiple clean faces; use one face per pass, then refold.
Damp-film technique: if using solvent, wet to a controlled damp state (not dripping).
Straight-line strokes: use consistent pressure and unidirectional strokes; avoid circular scrubbing.
Change-out triggers: discard when loaded, smeary, tacky, or when surface-quality requirements are at risk.

Method standardization tip: If outcomes differ by operator, lock four variables in the SOP: wetness target, stroke count, fold pattern, and change-out point.

Misuse controls & when not to use

If sterility is required: do not substitute a non-sterile wipe for sterile workflows.
If ultra-low residues/ions are gating: confirm requirements against current manufacturer documentation and your internal limits.
If the surface is easily scratched: validate on delicate finishes; avoid excessive pressure.
If chemistry is aggressive: verify compatibility and safety for solvents/cleaners; do not assume universal compatibility.

Recommended cleanroom glove pairing (ISO-aligned)

For ISO-controlled wiping applications, pair this cleanroom wipe with a cleanroom-processed, low-particle nitrile glove to reduce contamination transfer during handling and routine wipe-downs.

Ansell TouchNTuff® 83-500 Sterile Polyisoprene Gloves — sterile, ISO Class 5 (Class 100) positioning; polyisoprene for latex-like tactility without natural rubber latex proteins
Ansell TouchNTuff® 93-700 Sterile Disposable Nitrile Cleanroom Gloves — sterile, ISO Class 5 (Class 100) positioning; nitrile for broad chemical resistance and cleanroom-compatible handling

Glove discipline: Change gloves when contaminated, solvent-wet, torn, or after contacting non-controlled surfaces. Treat gloves as part of the wipe system.

Recommended sterile swab pairing (detail cleaning & confined geometries)

For ports, crevices, and recessed features where a wiper cannot maintain contact control, use a sterile cleanroom swab to keep the cleaning method consistent and to reduce accidental contact with critical surfaces.

Texwipe STX761 Sterile Alpha® Polyester Cleanroom Swab (Long Handle) — reach and precision for recessed features and narrow interfaces (verify method fit per SOP)
Texwipe STX712A Sterile CleanFoam® Swab (Rectangular Head) — broader contact patch for small flat surfaces and controlled solvent release (verify compatibility per SOP)

Swab discipline: Use a strict “one swab, one area” approach for sterile workflows. Do not re-dip; discard immediately if the tip is overloaded or if the swab contacts non-sterile surfaces.
