Cleanroom Wipers — Shop by Size 4"x4" to 18"x18" | ISO 3–8 Polyester, Nonwoven, Microfiber & Sterile Formats Choose the correct wiper size for the surface area, grip control, and solvent load—then match material/edge type to ISO class and SOP requirements. ▼ EXPAND SIZE GUIDE & TECHNICAL REFERENCE
Why Size Matters in Cleanroom Wiping
Wiper performance is not just material—size drives coverage, control, fold discipline, and solvent delivery. A wiper that is too small increases touch points and glove contact; too large can reduce control and increase the chance of edge drag on critical surfaces.
Selection should align with ISO classification (ISO 14644-1), surface sensitivity, chemistry used, and any documented process requirements. Sterile workflows supporting USP <797> / <800> should also consider packaging format (double-bag) and certification availability at point of use.
Shop by Wiper Size (Fast Guidance)
4"x4" (Small format)
Best for tools, fixtures, small wipe points, swab-adjacent cleaning, tight access areas.
Control note: excellent grip control; change frequently.
6"x6" / 9"x9" (General purpose)
Good balance of coverage and fold control for benches, carts, and equipment wipe-downs.
Rule of thumb: 9"x9" is a common standard for ISO 5–8 programs.
12"x12" (High coverage)
Faster coverage for larger stainless surfaces, doors, pass-throughs, and equipment panels.
Control note: maintain fold discipline to avoid edge drag.
14"x14" / 16"x16" (Large format)
Used for floors, large panels, and high-throughput wipe-downs where coverage speed matters.
Best practice: pair with controlled wetting and defined pass patterns.
18"x18" (Max coverage)
Specialty applications for very large surfaces; common in some facilities workflows.
Risk control: large wipes can reduce control—validate technique.
Rolls / Perforated wipes
Used where tear-to-length is needed; confirm linting/extractables profile and SOP fit.
Audit note: ensure consistent sheet length control if required.
Quick Size-to-Task Alignment
| Size | Best for | Control / risk note |
|---|---|---|
| 4"x4" | Tools, fixtures, small wipe points, tight clearances | High control; change frequently to avoid redepositing residue |
| 6"x6" / 9"x9" | Benches, carts, work surfaces, general wipe-downs | Best balance of coverage and fold discipline |
| 12"x12" | Larger equipment panels, doors, pass-throughs | Avoid edge drag; keep consistent fold pattern |
| 14"x14" / 16"x16" | Large surface wipe-downs, some facilities workflows | Validate wetness and pass pattern for repeatability |
| 18"x18" | Specialty max-coverage use cases | Potential control loss; confirm SOP compatibility |
| Rolls | Tear-to-length workflows, staged wiping sequences | Standardize sheet length if documentation requires it |
After Size: Match Material & Edge Type
- ISO 3–5 critical surfaces: sealed-edge knit polyester is commonly selected for fiber control.
- ISO 6–8 support areas: absorbent hydroentangled nonwovens are frequently used for speed and wet-out.
- Optics / glass: microfiber can support streak control when paired with approved chemistry.
- Repeatable solvent delivery: pre-wetted IPA wipes reduce operator variability across shifts.
- Sterile workflows: select sterile packaging formats and maintain certificate availability at point of use.
Common Audit Findings (Size & Technique)
- Over-sized wipe for critical work: reduced control leads to edge drag and uncontrolled contact.
- Under-sized wipe for large surfaces: excessive touch points increase glove contact and variability.
- Inconsistent fold discipline: reusing contaminated faces causes redeposition and streaking.
- Uncontrolled wetness: over-wetting spreads residues; under-wetting reduces removal efficiency.
