Texwipe TX1040 PolySat (7" × 11") is a pre-wetted polypropylene cleanroom wiper built for one primary outcome: make the alcohol step behave like a controlled process input instead of an operator-dependent variable. In real facilities, “mystery streaks,” re-clean loops, and inconsistent dry-down often trace back to solvent handling—open beakers, shared squeeze bottles, inconsistent wetness, and re-wetting mid-pass.

TX1040 addresses that failure mode by pairing a soft, melt-blown polypropylene substrate with a defined wetting system: a 0.2 µm filtered, 70% IPA / 30% deionized water solution in a resealable slider bag. The result is repeatable wetness at the point of use and fewer opportunities for back-contamination, evaporation drift, and uncontrolled solvent pooling.

Reliability is part of the control plan. Sourcing through SOSCleanroom helps programs standardize the wipe/solvent step with consistent replenishment, documentation continuity, and fewer last-minute substitutions that change outcomes.

TX1040 is intended for routine controlled cleaning where repeatable solvent delivery matters—wipe-down of benches, carts, tool exteriors, pass-through touchpoints, and general surfaces in ISO 5–8 environments. The 7" × 11" format is particularly practical for “tight-space” cleaning: hoods, access panels, small work zones, and around fixtures where full-size wipes can increase accidental contact risk.

Treat it as a non-sterile presaturated wipe unless your specific program requires sterile introduction controls; for aseptic workflows, use a validated sterile presaturated system aligned to your area classification and SOPs.

TX1040 earns a place in a cleaning program when the goal is to reduce solvent-driven variability without turning wiping into a chemistry project:

• Defined wetting system: presaturated with 0.2 µm filtered 70% IPA / 30% DI water to reduce mixing errors, dilution drift, and bottle-to-bottle variability.
• Substrate choice for solvent wipe-down: 100% melt-blown polypropylene supports common wipe-down workflows with straightforward handling and broad chemical compatibility for alcohol-based cleaning steps.
• Packaging as a control: a reclosable slider bag encourages open–dispense–reseal discipline and reduces evaporation-driven “half-strength by end of shift” behavior.
• SolventSafe packaging: packaged in plastic designed to be wiped down prior to introduction into controlled areas, supporting cleaner staging and transfer practices.
• Right-size format: 7" × 11" helps reduce overreach and improves access to smaller zones while still allowing stable folding and face rotation.
• EHS and shipping posture: alcohol presaturated wipes ship Ground only with a hazmat handling posture; build that into planning for kitting, field support, and replenishment.

In presaturated wiping, performance is not just “what the wipe is,” but “how the wipe delivers liquid.” TX1040 uses a melt-blown polypropylene nonwoven: a structure that holds solvent across a large internal surface area and releases it under controlled pressure at the wipe face. That matters because uncontrolled free liquid is a common failure mechanism—pooling at seams, wicking under interfaces, and dragging dissolved soils into the next feature.

The wetting solution is also part of the construction. A 70% IPA / 30% DI water blend is widely used because the water fraction improves wetting and soil mobilization for many real residues. The tradeoff is dry-down behavior: if you flood a surface or allow uneven drying, the water fraction can increase spotting or streaking risk on haze-sensitive surfaces. The engineering control is technique—light, single-direction passes and frequent face changes—plus a defined finishing method when the acceptance criterion is “no haze under defined lighting.”

Terminology matters. TX1040 is engineered for low-linting performance in controlled environments; no wiper is truly “lint-free” in every process condition. Surface texture, pressure, stroke direction, and overworking a loaded face determine whether fibers/particles become a problem.

For presaturated wipes, the most meaningful “performance metric” is often repeatability: the same wetness, the same wipe feel, and the same dry-down window across operators and shifts. TX1040’s control posture comes from the filtered, defined solution and the packaging discipline that limits evaporation and cross-contamination.

Treat manufacturer typical data (when provided) as a qualification starting point—not a substitute for process validation. If your program is residue-critical (optics, coatings, high-energy surfaces) or corrosion/ECM-sensitive (high-impedance electronics), qualify the wipe/solvent pairing in your actual acceptance window and consider a two-step approach: (1) controlled soil removal with TX1040, then (2) a finishing step aligned to the residue budget.

Presaturated wipes succeed or fail on packaging discipline. A resealable slider bag supports a basic but powerful control: dispense what you need, reseal immediately, and return the pack to controlled storage. That reduces evaporation drift and discourages re-dipping behaviors that collapse traceability and turn a wipe into a cross-contamination tool.

Presaturated wipes reduce variability, but they do not remove the need for disciplined technique. TX1040 performs best when operators:

• Stage the pack: open only when ready, dispense what you need, reseal immediately, and return to controlled storage.
• Fold for control: fold to create multiple clean faces; treat each face as single-pass for critical wipe-downs.
• Wipe cleanest to dirtiest: single-direction strokes with parallel, overlapping passes; avoid “back-and-forth scrubbing” unless the SOP calls for it.
• Control wetness at the surface: aim for damp wipe-down—not flooding. Avoid pushing liquid into seams, under interfaces, and into corners where solvent becomes a hidden failure mechanism.
• Do not top off the pack: adding extra alcohol changes saturation and undermines repeatability (and can introduce contaminants).
• Respect flammability controls: treat IPA wipes as flammable materials; follow facility requirements for ventilation, ignition-source control, storage, and waste handling.

Presaturated wipes are specifically designed to prevent predictable solvent-workflow failures. The remaining risk is almost always technique and handling:

• Leaving the bag open: drives evaporation and inconsistent strength. TX1040’s slider bag supports reseal discipline—use it.
• Overworking a loaded face: turns cleaning into redeposition. Prevent with aggressive face rotation and early discard.
• Over-wetting sensitive surfaces: increases streaking/spotting risk with 70/30 blends. Prevent by using lighter pressure and defined passes; step up to a finishing method when needed.
• Using cleaning wipes as sampling tools: if TOC/HPLC/residue recovery becomes the objective, treat sampling as a measurement system with method-aligned consumables and controls.
• Ignoring hazmat constraints: presaturated wipes ship and store differently than dry wipes. Build ground-shipping and storage controls into planning and kitting.

The most defensible comparisons are to other presaturated 70% IPA wipe systems intended for similar cleanroom wipe-down tasks.

Contec PROSAT (presaturated wipe programs) is a close comparator when packaging discipline and multiple substrate options are priorities. Evaluate substrate type and how well saturation holds across the pack life in your actual work cadence.

Berkshire SatPax (resealable pouch IPA wipes) is the appropriate comparator when you want a similar “controlled wetness” concept but prefer an alternate packaging configuration or fabric family. Qualification should be driven by residue behavior on your surfaces and day-to-day repeatability under operator handling.

TX1040 fits best in the standardized solvent wipe-down tier for ISO 5–8 environments—particularly where the dominant risk is variability in solvent handling, not solvent chemistry. Use it to stabilize routine wipe-downs, reduce open-container solvent handling, and improve repeatability across shifts. Keep the program mature by defining escalation tools: sealed-edge dry polyester for edge-driven releasable risk, and protocol-aligned sampling consumables when the wipe-down step becomes part of a measurement system.
