TX706A CleanFoam® Keyboard Cleanroom Swab (Closed-Cell Polyurethane Foam)

Texwipe TX706A CleanFoam® Keyboard Swab is a precision, low-linting (no swab is truly ‘lint-free’ in every process condition) closed-cell polyurethane foam cleanroom swab designed for keyboard and keypad cleaning in controlled environments, plus detailed cleaning in tight, contamination-prone gaps, recessed areas, intersecting surfaces, and joints. Built from high-quality 100 ppi polyurethane CleanFoam® with complete thermal-bond construction, TX706A helps reduce adhesive-related contamination risk at the head/handle interface while delivering durable scrubbing behavior and controlled solvent handling. It is cleanroom processed for low background contribution (typical low ions and low nonvolatile residue), lot coded for traceability, and packaged in silicone-free and amide-free bags to support contamination-control programs across microelectronics, semiconductor, optics, medical device, pharma, and other ISO-class workflows.

Process-control note: TX706A is often used as the “human-interface cleaning” control tool for keyboards, keypads, and operator touch surfaces—where skin oils, disinfectant residues, powders, and airborne particles accumulate and then re-transfer to gloves. Best outcomes come from damp (not dripping) technique, straight-line strokes, and frequent face rotation to prevent pooling in seams and dry-down film.

About the Manufacturer:

Texwipe (an ITW company) differentiates itself in contamination control by treating cleanroom swabs as engineered tools—defined materials, consistent geometry, controlled processing, and packaging intended to reduce background contribution and operator-to-operator variability. In CleanFoam® programs, the technical driver is the construction: 100 ppi polyurethane foam plus complete thermal bonding to remove adhesives as a residue/extractables variable at the head/handle interface, supported by lot coding and clean packaging controls.

SOSCleanroom (SOS) supports that manufacturing discipline with a close working relationship focused on continuity of supply, documentation discipline, and practical application support—helping customers standardize qualified swab materials and reduce substitution risk in critical environments.

TX706A Benefits:

Keyboard and keypad cleaning control: Geometry and foam behavior support repeatable cleaning between keys, along bezels, and at narrow crevices where contamination can re-transfer to gloves
Durable closed-cell performance: Closed-cell foam tends to behave more like a controlled cleaning face than a sponge, supporting consistent contact in edges and gaps (technique-dependent)
Reduced residue risk at the bond line: Thermal bonding removes adhesive at the head/handle interface—a common hidden residue pathway during solvent or disinfectant work
Lower background contribution: Typical cleanliness metrics help teams assess residue risk and support qualification planning (typical values, not specification limits)
Typical ionic extractables (µg/swab): Calcium 0.16; Chloride 0.62; Fluoride 0.18; Magnesium 0.04; Nitrate 0.04; Phosphate 0.38; Potassium 0.12; Sodium 0.12; Sulfate 0.18
Typical NVR (mg/swab): 0.15 (DI water extractant) and 0.48 (IPA extractant), useful for anticipating dry-down film risk when over-wetting drives solvent into seams
Traceability + line-side control: Lot coding and silicone-free/amide-free packaging support tighter investigations and more stable SOP training

Common Applications:

Keyboard and keypad cleaning in cleanrooms and controlled manufacturing areas
Applying and removing lubricants, adhesives, and other solutions in a critical clean environment
Scrubbing recessed areas and tight wipe points
Removal of excess materials and debris
Cleaning intersecting surfaces and joints
Cleaning with compatible solutions and solvents (validate chemistry compatibility and surface sensitivity)
Picking up fine powders during controlled handling steps
Microelectronics, semiconductor, optics/photonics benches, medical device assembly, pharma/biologics support areas

Best-Practice Use:

Damp-not-dripping control: Damp lifts and captures. Over-wetting floods gaps, pools under edges, and increases dry-down residue risk—especially on keyboards and keypads.
Straight-line strokes: Use one-direction, overlapping passes. Avoid circular scrubbing unless your procedure requires it; circles tend to push debris into seams.
Single-pass discipline: Rotate the foam face frequently and replace early. Continuing with a loaded face is how film and particles redeposit.
No re-dipping: Do not re-dip a used swab into shared solvent reservoirs. Use controlled dispense or dedicated aliquots to reduce cross-contamination.
Pressure control: Let the foam face and flexible paddle geometry do the work. Excess pressure can drive debris deeper and can increase abrasion risk on printed legends/coatings.
Validate solvent compatibility: Some keyboards/panels include plastics, markings, and adhesives sensitive to certain solvents. Document allowed chemistries in your SOP.

Selection Notes (TX706A vs. Other Options)

Closed-cell foam for scrubbing control: Choose TX706A when durability and controlled contact in gaps/edges is the priority (keyboard-style work and narrow crevices).
Thermal bond as a contamination control: If your process is sensitive to bond-line residues, prioritize thermal-bond swabs over adhesive-bonded alternatives.
Non-sterile vs. sterile introduction: TX706A is a non-sterile, dry swab. If you require sterile-at-point-of-use packaging, validated sterilization claims, and sterile documentation, choose a sterile configuration aligned to your quality system.
Qualification mindset: Treat published ions/NVR as typical analysis guidance. Qualify with your actual solvent system and substrate (swab blank, solvent blank, controlled dry-down inspection under your real defect-detection lighting).

ISO 14644 Operations Control CleanFoam® Keyboard Series (TX706A) Foam (closed-cell polyurethane) Keyboard profile; rigid handle Precision Cleaning / Slot & Crevice Access / Solvent Control Lot Traceability

Texwipe TX706A CleanFoam® Keyboard Swab (Closed Cell, Non-Sterile) — Slot-Focused Geometry for Tight Features Where Controlled Solvent Placement and Edge Contact Matter

Texwipe’s TX706A CleanFoam® Keyboard Swab is a cleanroom-processed, non-sterile foam swab designed around a keyboard-style profile to improve access and contact control in narrow features. Closed-cell polyurethane foam is often selected when solvent containment and low linting behavior are important, because the structure can help limit deep solvent hold-up and reduce fiber generation compared with many open structures. In controlled environments, keyboard-profile swabs are commonly applied to slots, seams, grooves, edges, connector features, and small recesses where a broad wiper cannot reach and a round swab does not provide the right contact geometry. Operational results typically depend on solvent selection, defined wetness targets (damp vs. wet), short unidirectional strokes, and rotating/advancing the swab to present a clean contact edge. Because the contact edge can load quickly in crevices, defined change-out triggers (loading, deformation, residue transfer) help reduce re-deposition and variability. For controlled or validated programs, confirm construction details, cleanliness positioning, and compatibility with your cleaning chemistry using current manufacturer documentation and lot records.

Operations takeaway: In cleanrooms, swabs are a precision tool. The outcome depends on head material, solvent loading, stroke discipline, and single-use/change-out rules.

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

ISO 14644-5:2025 places cleaning and handling activities under a documented Operations Control Programme (OCP). Swabs belong in that system because they directly influence localized contamination (particles, fibers, residues, and solvent carryover). Where swabs are used for precision cleaning (e.g., slots, seams, ports, fixtures) or verification-related activities, the method should be written, trained, and repeatable: approved solvent, defined wetness, defined motion (stroke count/direction), and defined change-out triggers.

Control point: Crevice cleaning failures are often driven by re-deposition. When the contact edge loads, the swab can begin transferring residue back into the feature—define discard cadence in the SOP.

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

Precision cleaning in narrow features: slots, seams, grooves, and edges where contact geometry matters
Controlled solvent application/removal (IPA, acetone, engineered solvent per SOP) with defined wetness targets and reduced pooling risk
Removing localized particulate or residue from connector features, tool interfaces, and small recesses
Detail cleaning on sensitive surfaces where a broad wiper cannot be controlled
Sampling/verification workflows only if applicable and permitted by your SOP

Selection note: Closed-cell foam is often chosen when solvent control and low linting are priority drivers. Validate against your surface finish and cleaning chemistry, then standardize wetness and discard rules.

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

Control introduction: bring swabs into the cleanroom per OCP rules (outer packaging removal, staging, storage).
Control wetness: load to a defined “damp” condition (not dripping). Excess solvent can drive pooling in slots and seams.
Directional strokes: use short, controlled, unidirectional strokes along the feature; avoid scrubbing that redistributes contamination.
Use the edge intentionally: maintain consistent contact pressure; rotate/advance the swab to keep a clean contact edge.
Change-out triggers: discard when the edge loads, deforms, sheds, or residue transfer is observed.
Waste discipline: discard immediately into the designated waste stream (do not stage used swabs on benches).

Method standardization tip: For slot cleaning, define stroke count per feature length and discard after a set number of passes.

Misuse controls & when not to use

If sterility is required: do not substitute non-sterile swabs for sterile workflows.
If you are sampling for validation: do not substitute cleaning swabs for protocol-defined sampling devices and methods.
If the chemistry is aggressive: verify compatibility of the foam construction/head bond and handle materials to the solvent.
If ESD is critical: use an ESD-safe swab/handle where required and validate resistance/grounding to your program.
