How to Clean Your Computer Safely (Inside and Out)

Over time, dust, dirt, and unnecessary files can slow down your computer and even cause hardware damage. Regular cleaning helps your device run faster, stay cooler, and last longer.

This guide covers both physical cleaning and digital cleanup - safely and effectively.

Part 1: Physical Cleaning (Hardware)

What You’ll Need

• Microfiber cloth

• Compressed air can

• Soft brush (optional)

• Isopropyl alcohol (70% or higher)

• Cotton swabs

⚠️ Always turn off and unplug your computer before cleaning.

Step 1: Clean the Screen

• Use a microfiber cloth.

• If needed, lightly dampen the cloth with water or screen cleaner.

• Never spray liquid directly onto the screen.

Step 2: Clean the Keyboard

• Turn the keyboard upside down and gently shake it.

• Use compressed air between keys.

• For sticky keys, lightly dip a cotton swab in alcohol and clean around them.

Step 3: Clean the Mouse

• Wipe the surface with alcohol.

• Clean the sensor area gently.

• For mouse wheels, use compressed air.

Step 4: Remove Dust from Vents

• Use compressed air to blow dust out of air vents.

• This helps prevent overheating.

💡 Tip: Do this every 2–3 months, especially if you have pets.

Part 2: Digital Cleaning (Software)

Step 1: Delete Unused Programs

• Uninstall apps you no longer use.

• This frees storage and improves performance.

Step 2: Clear Temporary Files

• On Windows: Use Disk Cleanup

• On macOS: Use Storage Management

Step 3: Run Antivirus Scan

• Run a full scan using Windows Defender or a trusted antivirus.

• Remove any detected threats.

Step 4: Update Your System
