Cleaning Computer Components
1. General Safety Precautions
- Turn off & unplug the computer before cleaning.
- Discharge static electricity by touching a grounded metal object or wearing an anti-static wrist strap.
- Use non-conductive cleaning tools (plastic brushes, microfiber cloth).
- Never spray liquids directly on components—spray on a cloth first.
2. External Cleaning
a. Case (Cabinet)
- Tools: Microfiber cloth, mild detergent, compressed air.
- Wipe exterior panels with a slightly damp cloth.
- Remove dust from vents using compressed air or a soft brush.
b. Keyboard
- Disconnect the keyboard.
- Turn upside down and gently shake to remove debris.
- Use compressed air between keys.
- Wipe with isopropyl alcohol (70%+) on a cloth or cotton swab.
c. Mouse
- Wipe body with alcohol-dampened cloth.
- For optical sensors, use a dry cotton swab to remove dust.
d. Monitor
- Turn off and unplug.
- Use a microfiber cloth (dry or lightly damp with water/distilled water).
- Avoid harsh cleaners; never press hard on the screen.
3. Internal Cleaning
(Do this every 3–6 months for best performance.)
a. Opening the Case
- Remove side panel carefully.
- Keep screws safe in a small container.
b. Dust Removal
- Compressed air: Blow short bursts to remove dust from fans, motherboard, RAM slots, PSU vents.
- Hold fan blades in place to avoid spinning while cleaning.
- Soft brush: Gently loosen stubborn dust without scratching.
c. CPU Cooler
- Remove dust buildup from heatsink fins.
- If thermal paste is old (>2 years), clean with isopropyl alcohol and reapply fresh paste.
d. RAM & Expansion Cards
- Remove sticks/cards carefully.
- Clean contacts with isopropyl alcohol and a lint-free cloth.
- Reinsert firmly into slots.
e. Power Supply
- Use compressed air from outside vents only.
- Do not open PSU unless you are trained—it contains dangerous voltages.
f. Storage Drives
- Just remove dust from surfaces and connectors.
- Avoid shaking or applying pressure.
4. Special Notes
- Avoid vacuum cleaners inside the case—they can generate static electricity.
- Label cables before disconnecting for easy reassembly.
- Clean regularly to prevent overheating and prolong component life.
