Alcohol dust-free wipes are high-cleanliness products widely used in electronics, optics, and medical industries. Punching full inspection is a critical step to ensure the quality and performance of each wipe, guaranteeing compliance with strict cleanliness standards and user requirements.

Full Inspection Process

1. Visual Inspection
   Check for visible defects such as tears, stains, or foreign particles.

2. Size Measurement
   Verify that the wipe dimensions meet design specifications to ensure cleaning effectiveness.

3. Fiber Integrity Testing
   Use microscopy to confirm no fiber shedding or breakage.

4. Liquid Absorption Test
   Measure the wipe’s ability to absorb alcohol and other liquids to ensure cleaning efficiency.

5. Cleanliness Testing
   Perform particle count and ionic residue tests to meet cleanroom standards.

Importance of Punching Full Inspection

• Ensures product consistency and reliability

• Prevents cleaning failures or device damage caused by poor quality

• Meets stringent customer and industry quality certifications

Strict full inspection of punched alcohol wipes guarantees superior cleaning performance and enhances customer trust and satisfaction.

Alcohol cleanroom wipes combine alcohol solution with microfiber dust-free cloth to create an efficient cleaning tool widely used in electronics manufacturing, medical devices, optical instruments, and cleanroom environments. Their main functions include:

1. Effective Cleaning
   The 70% isopropyl alcohol solution dissolves oils, fingerprints, and contaminants quickly, ensuring a clean and hygienic surface.

2. Low Fiber Shedding
   Made from microfiber, these wipes do not shed fibers or particles during cleaning, preventing secondary contamination.

3. Fast Evaporation
   Alcohol evaporates quickly, leaving surfaces dry without streaks or residue, improving cleaning efficiency.

4. Disinfection
   The alcohol content provides antibacterial effects, reducing microbial contamination and ensuring device safety.

5. Protecting Precision Equipment
   The soft, non-abrasive wipes are safe for cleaning sensitive surfaces such as smartphone screens, optical lenses, and electronic components.

With these benefits, alcohol cleanroom wipes are indispensable for high-standard cleaning tasks.

The usable time of dust-free wipes prewetted with alcohol depends on several factors including alcohol concentration, storage conditions, packaging seal, and usage frequency. Understanding these helps optimize use while maintaining cleaning effectiveness and safety.

1. Usage Life
Typically, dust-free wipes wetted with 70% isopropyl alcohol should be used within a few hours after opening to prevent alcohol evaporation and loss of moisture, which reduces cleaning efficiency. If well sealed and stored in a cool, dry place, they can remain moist for several days, but prompt use is recommended for best performance.

2. Influencing Factors

• Sealing: Good airtight packaging slows alcohol evaporation, extending usable life.

• Temperature and Humidity: High temperatures and dry air accelerate evaporation, shortening usage time.

• Frequency and Method of Use: Frequent opening or prolonged exposure to air speeds up alcohol loss.

3. Storage Recommendations

• Seal the package immediately after use to prevent evaporation.

• Store in a cool, ventilated area away from heat sources and flames.

• Avoid re-wetting wipes to prevent contamination and degrade performance.

In summary, alcohol-prewetted dust-free wipes are best used within a short period after opening, and proper storage can slightly extend their effectiveness to ensure cleaning quality and device safety.
