Many wonder if alcohol-prewetted cleanroom wipes can be reused to save resources. Since alcohol evaporates quickly, limited reuse is possible under proper conditions, but cleanliness and safety must be strictly maintained.

1. Conditions for Reuse

• Most alcohol has evaporated, and the wipe is moderately moist after first use.

• The wipe is free from visible contamination, damage, or microbial buildup.

• Used for cleaning non-critical surfaces with lower cleanliness requirements.

2. How to Reuse

• Handle wipes with clean gloves to avoid contamination.

• Air out the wipe briefly to allow alcohol to evaporate.

• Optionally reapply a small amount of alcohol to maintain moisture before reuse.

• Avoid reusing on high-cleanliness or sensitive electronic components.

3. Precautions

• Do not reuse multiple times to prevent reduced cleaning efficacy and hygiene risks.

• Dispose of wipes promptly after use to prevent bacterial growth.

• Never reuse wipes in medical or high-risk environments.

In summary, limited reuse of alcohol-prewetted cleanroom wipes is possible under specific conditions but prioritize cleaning effectiveness and safety.

75% alcohol (usually 75% isopropyl or ethyl alcohol) is widely used for cleaning and disinfecting electronics. A common question is whether it conducts electricity, which is important for safe use.

1. Conductivity of 75% Alcohol
Pure alcohol is an insulator and does not conduct electricity. However, 75% alcohol contains 25% water, and dissolved minerals and ions in the water give it some conductivity. Although this conductivity is low, it can still pose a short-circuit risk for sensitive electronic components.

2. Safety Tips

• Avoid letting large amounts of liquid pool or seep into electronic circuits.

• Use alcohol-prewetted cleanroom wipes to minimize liquid volume and reduce risk.

• Ensure the device is completely dry after cleaning to prevent electrical issues caused by residual moisture.

3. Conclusion
75% alcohol solution has low but present conductivity, so caution is needed when cleaning electronics. Proper handling and thorough drying are key to safe use.

Alcohol nonwoven fabric is a cleaning and disinfecting material made from soft nonwoven fabric pre-soaked or sprayed with alcohol—typically 70% isopropyl or ethyl alcohol. It is widely used in personal hygiene, healthcare, industrial cleaning, and public sanitation due to its convenience, efficiency, and strong disinfecting properties.

1. Main Uses of Alcohol Nonwoven Fabric

• Personal Hygiene
  Ideal for quick hand and skin disinfection, especially when soap and water are unavailable.

• Electronics Cleaning
  Perfect for wiping fingerprints, grease, and dust off phones, tablets, keyboards, and other devices.

• Medical and Laboratory Use
  Commonly used to disinfect instruments, surfaces, and workstations to maintain sterile environments.

• Industrial Cleanroom Maintenance
  Used for spot cleaning equipment and surfaces in cleanroom and precision manufacturing environments.

• Public Area Disinfection
  Suitable for wiping high-touch surfaces like door handles, elevator buttons, and seats in public transport.

2. Key Features and Benefits

• Contains 70% alcohol for powerful disinfection and fast drying with no residue

• Soft nonwoven fabric is lint-free and gentle on surfaces

• Available in individually wrapped or pull-out packaging for easy use

• Versatile for daily and professional cleaning needs

When a phone or tablet is stored or transported in contact with a physical keyboard, visible “keyboard imprints” can appear on the screen. These marks are usually caused by pressure, skin oils, and dust. Using alcohol with a cleanroom wipe is a safe and effective way to remove them without damaging the screen.

1. Tools Needed

• Microfiber cleanroom wipe

• 70% isopropyl alcohol (IPA) or alcohol-based screen cleaner

• Soft lighting for clear visibility

2. Cleaning Steps
① Lightly spray alcohol onto the cleanroom wipe—do not spray directly onto the screen.
② Gently wipe the screen in a circular motion over the imprints.
③ For stubborn marks, repeat the process until the screen is clear.
④ Use a dry cleanroom wipe to remove any remaining moisture.
⑤ Let the screen air dry for a few minutes before using the device.

3. Precautions

• Use 70% alcohol to avoid damaging screen coatings.

• Prevent alcohol from seeping into openings like speaker grills or charging ports.

• Avoid using tissues or regular cloths to prevent scratches.
