In environments such as electronics manufacturing, precision instruments, and cleanrooms, cleaning is critical. Cleanroom wipes are designed to be lint-free and particle-free, making them ideal for use with alcohol (such as 70% isopropyl alcohol) for effective cleaning. This article explains the correct method of cleaning with cleanroom wipes and alcohol to ensure optimal cleaning results and equipment safety.
1. Preparation
-
Choose cleanroom wipes that meet cleanliness standards with no dust or fiber shedding.
-
Select the appropriate alcohol concentration, preferably 70% isopropyl alcohol or medical-grade ethanol, which evaporates quickly and disinfects effectively.
-
Prepare a clean spray bottle or pre-wetted cleanroom wipes.
2. Cleaning Steps
-
Apply Alcohol: Spray the alcohol onto the cleanroom wipe rather than directly onto the device surface to avoid liquid ingress and damage.
-
Wiping Motion: Gently wipe the device surface in one direction to prevent static buildup or scratches caused by back-and-forth rubbing.
-
Apply Moderate Pressure: Use enough pressure to remove dirt and oils without damaging the surface.
-
Replace Wipes When Needed: For larger or heavily soiled areas, use a fresh wipe to prevent recontamination.
-
Air Dry: Allow the surface to dry naturally as the alcohol evaporates.
3. Precautions
-
Avoid alcohols containing chlorine or corrosive solvents to protect device surfaces.
-
Ensure proper ventilation to prevent alcohol vapor buildup.
-
Do not clean devices while powered on to ensure safety.
-
Regularly replace wipes to maintain cleanliness.
Summary
Using cleanroom wipes combined with alcohol is an efficient and reliable cleaning method, especially suitable for electronics, optical instruments, and high-cleanliness environments. Following correct procedures and precautions significantly enhances cleaning effectiveness and prolongs equipment lifespan.
