Sterile Pre - moistened Wipes: Key Tools for Cleanroom Cleaning and Usage Guidelines

 

In high - precision industries such as pharmaceuticals, biotechnology, and electronics manufacturing, the maintenance of a clean environment is directly related to product quality and safety. As a core cleaning tool, sterile pre - moistened wipes, with their standardized sterilization treatment and ready - to - use design, have become the preferred solution for surface cleaning and disinfection in cleanrooms. The following provides a comprehensive analysis from product characteristics, application scenarios, and usage specifications.

 

I. Core Advantages of Sterile Pre - moistened Wipes

1. Ready - to - use Sterile Assurance

These wipes are pre - soaked in a mixed solution of 70% isopropyl alcohol (IPA) and 30% deionized water before leaving the factory. They are processed through sterilization technologies such as gamma rays or ethylene oxide to ensure they meet the 10^-6 - level sterile standard. The independently sealed three - layer sterile packaging design further blocks external contamination, meeting the requirements of high - demand scenarios such as GMP Class A/B clean areas.

2. Precise Cleaning Performance

Made of polyester fiber or double - woven dust - free cloth material, they have both a high liquid absorption rate and ultra - low fiber shedding characteristics (usually <0.1 particle/cm²). They can efficiently remove microorganisms, dust, and liquid residues while avoiding the risk of secondary contamination during the cleaning process.

3. Compatibility and Safety

The IPA solution is non - corrosive to most cleanroom surfaces (such as stainless steel, glass, and plastic), and the anti - static design can protect sensitive equipment such as electronic components. In addition, the pre - measured soaking technology avoids solvent waste, saving approximately 30% of chemical usage compared with the traditional cleaning method of dry cloth + spraying.

 

II. Analysis of Typical Application Scenarios

1. Pharmaceutical and Biotechnology Fields

In Class A/B clean areas such as filling lines and isolators, they are used for the terminal cleaning of equipment surfaces after sterilization to ensure no pyrogen residues. Their low particle release characteristics meet the FDA's environmental monitoring requirements for sterile preparation production.

2. Electronics Manufacturing and Optical Industries

They are suitable for decontamination of PCB boards before SMT mounting, streak - free cleaning of optical lenses, and maintenance of semiconductor production equipment. The anti - static performance can prevent electrostatic discharge (ESD) damage to precision components.

3. Daily Laboratory Management

They are used for the regular disinfection of ultra - clean workbenches, biological safety cabinets, and analytical instruments to ensure the reliability of experimental data.

 

III. Standardized Operating Specifications

1. Opening and Taking

- Check the integrity of the packaging before use. After opening, use the wipes within 1 hour to avoid the evaporation of the solution affecting the cleaning effect.

- Wear sterile gloves for operation to avoid direct contact of fingers with the wiping area.

2. Key Points of Wiping Technology

- Use the one - way overlapping wiping method to ensure full surface coverage and no repeated contamination.

- For irregular surfaces (such as valves and pipe interfaces), folding operations can be carried out with the help of sterile tweezers.

3. Waste Disposal

Used wipes should be classified and treated as hazardous waste. Products containing IPA solvent should be sealed and handed over to professional institutions for incineration. Do not discard them casually.

 

IV. Purchase and Storage Suggestions

1. Principle of Parameter Matching

Select the corresponding sterilization method according to the clean level (for example, in ISO Class 4 areas, products sterilized by gamma rays are preferred); select the IPA concentration according to solvent tolerance (a 70% concentration is recommended for the electronics industry, and a low - concentration ethanol formula can be selected for the medical device industry).

2. Control of Storage Conditions

Unopened products should be stored in a cool and dry environment (the recommended temperature is 15 - 25°C, and the humidity is <60%) to avoid degradation of the packaging material caused by direct ultraviolet radiation.

 

Sterile pre - moistened wipes improve the cleaning efficiency of cleanrooms by more than 40% through a standardized production process and strict quality control, while reducing the risk of contamination caused by human operational errors. With the implementation of the new GMP and ISO 14644 standards, these innovative cleaning tools are becoming an essential element of the environmental management system in high - precision industries.
