Is your phone screen grimy, or do you need to clean up after soldering that gaming PC? Learn how to safely use isopropyl alcohol (IPA) for cleaning electronics and when alternative solutions might be better.

What Makes IPA Ideal for Cleaning Electronics?

Isopropyl alcohol is widely used for cleaning electronics due to its unique properties:

• Evaporates Quickly: Prevents moisture damage to delicate components.
• Residue-Free: Leaves no residue, ensuring a clean finish.
• Non-Conductive: Safe for electrical components.

IPA vs. Other Cleaners

1. Ethanol: While similar, IPA is often preferred as it evaporates cleaner, leaving fewer residues.
2. Acetone: A powerful solvent, but its strength can damage plastics and sensitive components. Use with caution.
3. Water and Vinegar: A mild cleaning solution for external surfaces but unsuitable for internal components or removing tough residues.

Why Choose IPA?

1. Sanitization: IPA (60-70%) effectively kills germs, with slower evaporation for better dwell time.
2. Grime Removal: High-concentration IPA (90-99%) dissolves oils, adhesives, and flux residue efficiently.
3. Corrosion Prevention: Can help clean water damage but requires expertise.

How to Clean Electronics with IPA

1. Choose the Right Concentration:
   • 60-70% IPA: Best for external cleaning and sanitization.
   • 90-99% IPA: Ideal for water-sensitive internal components.
2. Prepare Safely:
   • Turn off and unplug devices.
   • Work in a ventilated area, away from flames.
   • Use protective gear for high concentrations.
3. Apply Sparingly:
   • Use lint-free cloths, microfiber cloths, or foam swabs.
   • Avoid spraying IPA directly on the device; apply to the cloth instead.
4. Allow to Dry:
   • Ensure all components are completely dry before reassembly or powering on.

Cleaning Recommendations by Device

• Smartphones/Tablets: Avoid direct application to screens. Use a damp cloth or a water-vinegar solution for touchscreens with oil-repellent coatings.
• TVs: Use a microfiber cloth or a damp cloth for smudges. For stubborn marks, a water-vinegar solution works well.
• Media Equipment (DVD Players, Remotes, etc.): Use 60-70% IPA for external surfaces.
• Keyboards, Mice, Game Controllers: Clean with 60-70% IPA to remove oils and dirt effectively.

Precautions

• Avoid overuse of IPA to prevent pooling.
• Always ensure devices are powered off and unplugged.
• Do not use IPA on components with sensitive coatings unless verified as safe.

By following these guidelines, you can use isopropyl alcohol to clean your electronics safely and effectively, maintaining their longevity and performance.
