The Complete Guide to Using Alcohol Lint-Free Wipes:

1. Key Benefits of Alcohol Lint-Free Wipes

• Effective Cleaning: 70-75% alcohol quickly dissolves grease and fingerprints

• Residue-Free: Medical-grade ethanol evaporates completely (<0.01ppm residue)

• Wide Applications: Electronics/medical devices/optical lenses

2. 4-Step Standard Operating Procedure

1. Material Selection:

   • Electronics: 99% isopropanol + Class 100 wipes

   • Medical: 75% ethanol + sterile packaging

2. Pre-Cleaning:

   • Remove large particles with air blower

3. Wiping Technique:

   • Unidirectional straight-line wiping (no circular motions)

   • Single-use per wipe side

4. Post-Cleaning:

   • Air-dry for 2 minutes

   • Inspect under white light

3. Industry-Specific Solutions

• Semiconductors:

  • ESD-safe wipes + 99% IPA

  • Post-wipe nitrogen purge

• Medical:

  • Sterile wipes + 75% ethanol

  • Follow WHO hand hygiene protocols

4. Five Critical Don’ts

⚠️ Never spray alcohol directly (apply to wipe first)
⚠️ Never reuse wipe surfaces
⚠️ Never clean powered equipment
⚠️ Avoid acrylic/polycarbonate surfaces
⚠️ Never use in confined spaces

5. Troubleshooting

• Hazing: Switch to chromatographic-grade alcohol

• Fiber Shedding: Use laser-edged wipes

• Poor Cleaning: Pre-clean with ultrapure water
