Cleanroom wipes play a crucial role in maintaining the stringent cleanliness requirements of controlled environments.
These specialized wipes are designed to remove surface contaminants like particles, liquids, and bio-contaminants while minimizing lint and shedding, making them indispensable for industries such as pharmaceuticals, semiconductors, electronics, and healthcare.
In this comprehensive guide, we’ll delve into the types, features, and applications of lint-free wipes, helping you choose the right product for your specific needs.
What Are Cleanroom Wipes?
With a wide range of materials, sizes, and grades available, cleanroom wipes can be tailored to meet the unique demands of your industry.
Lint-free wipes are specially engineered cleaning tools used in environments that demand strict contamination control.
Unlike ordinary wipes, cleanroom wipes are manufactured using advanced materials and processes to ensure low particle release, high absorbency, and compatibility with various cleaning agents.
Common uses include:
- Removing dust, dirt, and liquid spills from sensitive surfaces.
- Cleaning precision instruments, electronic components, and optical devices.
- Maintaining cleanliness in ISO-certified cleanrooms and laboratories.
Key Features of Cleanroom Wipes
- Low Lint and Shedding: Engineered to minimize contaminants and ensure surface cleanliness.
- High Absorbency: Quickly absorbs liquids and solvents, making cleaning more efficient.
- Chemical Resistance: Compatible with alcohols, acids, and other cleaning agents.
- Sterility Options: Available in sterile (gamma-irradiated) and non-sterile formats for different applications.
- Non-Abrasive: Soft and gentle on delicate surfaces to prevent scratches or damage.
- Durability: Strong and tear-resistant, even when wet.
Types of Cleanroom Wipes
There are three primary types of Controlled environment wipes, each designed for specific applications and environments:
1. Woven Cleaning Wipes
Woven wipes are made from continuous filament polyester, making them the cleanest and most durable option. These wipes are ideal for critical environments such as ISO Class 4–5 (Class 10–100) cleanrooms.
Advantages:
- Non-shedding and tear-resistant.
- Low in particles, suitable for critical applications.
- Soft and non-abrasive, safe for sensitive surfaces.
- Can be gamma-irradiated for sterility.
Edge Finishes:
- Knife Cut: Basic edge finish.
- Laser Sealed: Reduces particle generation.
- Ultrasonic Sealed: Offers the highest level of cleanliness.
2. Non-Woven Cleaning Wipes

Non-woven wipes are made by bonding fibers through heat, pressure, or chemical treatments. They are more economical than woven wipes and suitable for less critical environments.
Common Materials:
- Polyester/Cellulose Blends: High absorbency, durable, and resistant to acids and chemicals.
- Hydroentangled Rayon/Polyester: Soft, highly absorbent, and compatible with solvents like IPA.
- Polypropylene/Cellulose: Durable and resistant to acids, ideal for general cleaning tasks.
Advantages:
- Cost-effective.
- High liquid sorbency.
- Strong and durable.
- Low linting compared to ordinary wipes.
3. Pre-Saturated Cleaning Wipes
These wipes come pre-moistened with cleaning solutions, saving time and ensuring consistent application of cleaning agents.
Common Solutions:
- Isopropyl Alcohol (IPA)
- Denatured Ethanol (DE)
- Sodium Hypochlorite (Bleach)
- Hydrogen Peroxide
Advantages:
- Ready-to-use convenience.
- Consistent solution saturation.
- Available in sterile and non-sterile options.
Sterile vs. Non-Sterile Cleaning Wipes
Sterile Clean Wipes
Verified to a 10⁻⁶ SAL, Our sterile polyester knit cleanroom wipes are made from 100% continuous-filament polyester with a robust knit structure and sealed edges.
Sterile wipes are gamma-irradiated to eliminate all living organisms, making them ideal for healthcare, pharmaceutical, and biotechnology applications.
What is Gamma Irradiation? Gamma irradiation is a sterilization process that uses gamma rays to destroy microorganisms. This method is highly effective, penetrating products even in sealed packaging to ensure sterility.
Applications:
- Pharmaceutical manufacturing.
- Medical device production.
- Cleanrooms with ISO Class 4 or higher requirements.
Non-Sterile Wipes
Non-sterile wipes are used in environments where sterilization is not critical. They are suitable for general cleaning tasks in electronics, optics, and industrial applications.
Specialized Cleanroom Wipes for Laboratories and Industry
For laboratories and controlled environments outside of cleanrooms, there are specialized wipes designed for durability and low linting:
Materials:
- Rayon/Polyester Blends: Durable and chemically compatible.
- Rayon/Cellulose: Biodegradable and soft, ideal for cleaning optical lenses.
- Rayon: Heat-resistant and lightweight, suitable for use with disinfecting solutions.
Applications:
- Cleaning laboratory instruments and surfaces.
- Wiping delicate optics and lenses.
- General maintenance in controlled environments.
Choosing the Right Cleanroom Wipe
When selecting a cleanroom wipe, consider the following factors:
- Cleanroom Class: Match the wipe’s cleanliness level to the environment’s requirements (e.g., ISO Class 4–10).
- Material: Choose based on the surface being cleaned and the cleaning agent used.
- Sterility: Opt for sterile wipes for critical applications like medical or pharmaceutical production.
- Absorbency: Select highly absorbent wipes for liquid spills or solvent applications.
- Durability: Ensure the wipe can withstand the cleaning process without tearing or shedding.
