A short-handle microdenier swab earns its keep when the defect mechanism is not dramatic — it is small, stubborn, and expensive. A faint haze line on an optic, a particle parked in a corner of a ferrule, residue at an intersecting surface, or a fine powder that keeps reappearing after “cleaning” usually points to the same root causes: the wrong contact material, the wrong wetness, or the wrong stroke discipline.

Texwipe’s TX758MD is built for that narrow but high-impact zone: precision spot cleaning and particulate pickup where you need controlled contact, low background contribution, and repeatable handling in tight spaces. SOSCleanroom supports it because micro-swab work is where operators are tempted to substitute, and substitution is where consistency, traceability, and validated outcomes start to drift. Texwipe’s documentation posture (lot coding, published contamination data, and defined packaging controls) is also a practical advantage when investigations require more than “we used a swab.”

Nothing is truly lint free in every condition; low-linting outcomes depend on technique and surface condition, including edge sharpness, burrs, solvent load, contact pressure, and stroke discipline.

TX758MD is a compact, flexible paddle microdenier swab designed for precision cleaning and controlled application and removal of solutions in critical environments. It is commonly used for:

• Applying and removing lubricants, adhesives, and other solutions in a critical clean environment
• Scrubbing recessed areas and cleaning intersecting surfaces and joints
• Removing excess materials or debris and picking up fine powders
• Spot cleaning on scratch-sensitive surfaces where streak control matters

It is a practical fit across microelectronics and semiconductor workcells, optics and photonics benches, medical device assembly, data storage and precision electromechanical builds, and regulated life sciences environments where contamination control is part of the daily workflow.

• Microdenier contact behavior: 100% polyester knit microdenier increases effective surface area and micro-grip, improving pickup of fine particulate and helping reduce streaking when technique is controlled.
• Bond-line risk control: complete thermal bond construction eliminates adhesive at the head-to-handle interface, removing a common hidden residue variable in solvent-wet work.
• Dexterity in tight spaces: compact handle and flexible paddle improve access, angle control, and pressure control on small targets.
• Clean baseline for sensitive steps: published ionic extractables and nonvolatile residue support background-setting and method development for residue-sensitive processes.
• QAC compatibility: positioned for use with quaternary ammonium chloride cleaners and disinfectants (validate to your chemistry, surface, and residue requirements).
• Program stability: SOSCleanroom’s long-standing relationship with ITW Texwipe supports continuity of supply, lot traceability, and documentation discipline so qualified methods stay stable across replenishment cycles.

Head: 100% polyester knit microdenier; flexible paddle geometry for controlled contact in confined areas.

Bond: thermal bond construction (no adhesive at the bond).

Handle: polypropylene (virgin polypropylene handle); light-green handle color.

Operational traceability cue: trademarked light-green handles with “TEXWIPE” embossed on the handle are a practical line-side segregation and verification cue, especially when multiple swab types are staged at one bench.

TX758MD’s small head and compact handle are designed for controlled, repeatable contact in tight features where over-wetting and over-pressure are the common failure modes. The flexible paddle helps maintain uniform contact across small surfaces and along edges, but it also demands discipline: keep stroke direction consistent, rotate faces, and stop before the fabric becomes a transfer tool.

The numbers below represent typical analyses, not specification limits. In practice, “typical” matters because it sets your background contribution when you are trying to distinguish part-generated residue from consumable-generated residue. It also matters because wetness, solvent choice, and contact pressure can change what transfers. Use these values to support qualification work, blank controls, and investigation logic rather than as a pass/fail claim.

Testing note: the manufacturer references test method availability upon request (TM2 for swabs) and states these values represent typical analyses, not specification limits.

• Packaging: 500 swabs per reclosable bag; 5 bags per case. Manufacturer describes reclosable, silicone-free bag packaging.
• Sterility status: TX758MD is supplied as a dry, non-sterile swab. Manufacturer materials also note sterile swabs may be available upon request; if point-of-use sterility and labeled sterility assurance are required, specify a sterile product and packaging format that fits your quality system.
• Traceability: lot coded for traceability and quality control; light-green “TEXWIPE” embossed handle supports line-side segregation and verification.
• Shelf life and storage: 5 years from date of manufacture; store at ambient conditions (59°F to 86°F).
• Country of origin (manufacturer statement): made in the Philippines.

TX758MD performs best when you treat it as a controlled-contact tool rather than a general-purpose scrubber. The goal is to lift and capture without flooding geometry, smearing dissolved soils, or re-depositing what you just removed.

• Damp solvent technique: dispense a controlled amount of solvent (often IPA where validated) to the swab head. “Damp” means the head darkens and wicks but does not drip when held tip-down. If you see a bead forming, you are over-wet. Avoid flooding corners and avoid creating tide marks on drydown.
• Stroke count logic: use single-direction strokes with overlap. Plan a short, defined stroke count, then rotate to a fresh face. Stop when you see streaking, drag lines, or visible loading. Do not keep “polishing” with a loaded face.
• Geometry control: for tracks, slots, and channels, use the paddle edge as a controlled contact line. Keep gloves and sleeves out of the feature. Use the compact handle to maintain angle stability and avoid wrist-driven “scrub arcs” that smear soil across edges.
• Pressure guidance: apply only enough pressure to maintain full contact. Excess pressure increases smear risk, can drive particles into corners, and can cut or snag fabric on burrs or sharp edges. If you need higher force, reassess chemistry, dwell time, and tool selection.
• Solvent compatibility: IPA is common, but compatibility is process-specific. Validate solvent and dwell time against coatings, plastics, inks, and adhesives. If QAC disinfectants are used, treat residue control as part of the method (many programs require a follow-up step per SOP).
• Handling discipline: open the reclosable bag only as long as needed. Stage swabs on a clean surface or tray per SOP. Do not touch the head. Avoid re-dipping into shared solvent; use aliquots or one-way dispense to prevent cross-contamination.
• Disposal and documentation cues: discard after the defined step; do not “save” a damp swab for later. When the step is investigation- or QA-relevant, capture swab lot, solvent lot, and operator/shift in the traveler or log so root-cause work is defensible.

• Over-wetting: flooding corners or seams moves dissolved soils instead of removing them and can dry into residue rings. Control dispense volume and teach what “damp” looks like in-glove.
• Re-deposit from a loaded face: repeated passes with the same contact surface turns a cleaning tool into a transfer tool. Use defined stroke counts, rotate faces, and replace early.
• Over-pressure and snagging: dragging across burrs or sharp edges can cut fabric and generate fibers. Reduce pressure, change approach angle, and correct the edge condition if possible.
• Re-dipping into shared solvent: this is a common cross-contamination mechanism. Use aliquots or controlled dispense.
• Uncontrolled substitutions: similar-looking swabs can have different wetting and extractables behavior. Use lot-coded product through a stable supply channel to keep the qualified consumable in the process.

Competitor selection should be based on the mechanism that matters in your step: contact material (microdenier knit vs other fine-fiber constructions), bond method, published cleanliness data, packaging controls, and traceability discipline.

• Berkshire Lab-Tips LTP70F (small knitted polyester swab with flexible tip): similar compact format and flexible paddle intent for grooves, slots, and recessed areas. The functional differentiator is often microdenier pickup and streak behavior versus standard knitted polyester, plus the cleanliness metrics and documentation posture you need for residue-sensitive work.
• Puritan PurSwab 3130 (small microfiber swab with polypropylene handle): a fine-fiber alternative positioned for solvent use and precision cleaning. Compare bond method, packaging controls, and published extractables/NVR support against your qualification needs, especially when the step is inspection-driven and background contribution matters.

TX758MD sits in the precision-cleaning tier: fine particulate pickup, optics-adjacent touch cleaning, microelectronics assemblies, and small-feature work where contact control is as important as chemistry. In ISO-classified environments (ISO 14644-1 context) and regulated manufacturing environments (FDA context), the practical requirement is repeatable technique, defined endpoints, and documented consumable control.

SOSCleanroom supports controlled-environment programs with continuity of supply, responsive customer service, and a documentation-forward approach that helps customers avoid qualification drift. If the step is validation- or release-critical, qualify the swab in context: define area, strokes, wetness, solvent system, and inspection or extraction endpoints. Build blanks into the workflow and train operators on the behaviors that prevent recontamination.
