maintenancePC Cleaning Service Dhaka — How to Clean Your Computer at Home (2026 Guide)
5 July 2026 · 13 min read · BAYAS Editorial
A professional PC cleaning service in Dhaka costs BDT 1,500–3,000 for a home visit. Most desktops need deep cleaning every 6–12 months — faster in dusty areas like Mirpur, Mohammadpur, and Old Dhaka. Overheating due to dust is the single most common cause of sudden PC shutdowns in Bangladesh's hot, humid climate.
Dust is the silent killer of computers in Dhaka. Between April and October, temperatures routinely exceed 35°C — and a dust-clogged heatsink can push your CPU above 90°C, triggering thermal shutdowns or permanent damage. This guide explains when you can clean your PC yourself, how to do it safely, and when to call a professional cleaning service.

Why Does a PC Get So Dirty in Dhaka?
Dhaka's air quality and climate create near-ideal conditions for PC dust accumulation:
- High particulate count — construction dust, vehicle exhaust, and seasonal sand storms coat every horizontal surface, including PC air intakes.
- Humidity cycling — 80–95% relative humidity in monsoon season causes dust to clump and stick to heatsink fins rather than blow through.
- Fan-forced airflow — desktop and laptop cooling fans actively pull air (and debris) through the case all day.
- Power cuts and UPS cycling — load-shedding means PCs start and stop frequently; each startup pulls a fresh gulp of dusty air.
A desktop PC in a typical Dhaka apartment accumulates enough dust in 6 months to reduce airflow by 40–60%, raising CPU temperatures by 15–25°C. In summer, that difference can mean the gap between a stable 75°C and a shutdown-triggering 95°C.
What Are the Warning Signs Your PC Needs Cleaning?
| Warning Sign | What It Means | Risk Level |
|---|---|---|
| Fan running louder or constantly at max | Heatsink clogged — fan compensating | High |
| PC shuts down after 20–30 minutes of use | Thermal shutdown protection triggered | High |
| CPU temperature above 80°C at idle | Dust insulating the heatsink fins | High |
| Blue screen (BSOD) after recent hot season | Thermal stress on CPU/RAM solder joints | High |
| Visible grey lint on case vents | Active dust ingestion in progress | Medium |
| PC takes longer than usual to cool after shutdown | Poor internal airflow | Medium |
| Fan noise has changed pitch or rhythm | Dust on fan blades causing imbalance | Medium |
| Keyboard keys sticky or sluggish (laptop) | Debris under keys | Low–Medium |
If you see two or more of these signs, your PC needs cleaning within the next 1–2 weeks. Continuing to run a dust-clogged system risks permanent damage to the CPU, GPU, or motherboard from repeated thermal cycling.
How to Clean Your PC at Home in Dhaka — Step-by-Step
What You Need Before Starting
- Can of compressed air (available at Agargaon IDB Bhaban, Multiplan Center, or most computer shops — approximately BDT 400–800)
- Soft lint-free microfibre cloth
- Isopropyl alcohol (70% or above) — BDT 150–300 at pharmacies
- Phillips-head screwdriver (if opening desktop case)
- Antistatic wrist strap (optional but recommended — BDT 200–400)
Desktop PC Cleaning — 7 Steps
- Shut down and unplug — power off completely, not sleep or hibernate. Unplug the power cable from the wall.
- Move to an open area — carry the PC to a balcony, corridor, or space where dust can blow away rather than settle back inside.
- Ground yourself — touch a grounded metal object or use an antistatic strap to discharge static before opening the case.
- Open the side panel — usually two thumb screws on the back. Lay the PC on its side on a clean surface.
- Blow dust from vents, heatsinks, and fans — hold compressed-air cans upright, use short bursts (2–3 seconds), and keep the nozzle 10–15 cm from components. Hold fans still with a pen while blowing — spinning fans from compressed air can damage bearings.
- Clean the case vents from the outside — use a microfibre cloth dampened slightly with isopropyl alcohol on exterior metal surfaces and fan grills.
- Reassemble and test — replace the side panel, reconnect power, boot, and open a temperature monitor (HWMonitor or HWInfo64 — both free) to verify CPU and GPU temps have dropped.
What NOT to Do When Cleaning a PC at Home
Never use a household vacuum cleaner directly on PC components — it generates static electricity that can instantly kill a motherboard, GPU, or SSD. Use compressed air only for internal components.
- Do not spray water or household cleaning sprays inside the case
- Do not use tissues or paper towels (they leave fibres and generate static)
- Do not hold compressed-air cans at an angle — liquid propellant can spray onto components
- Do not clean thermal paste off the CPU without replacing it with new compound
Laptop Cleaning — Key Differences
Laptops are more difficult to clean at home without disassembly:
| Laptop Cleaning Method | What It Achieves | Limitation |
|---|---|---|
| Compressed air through vents (without opening) | Dislodges loose surface dust | Pushes dust deeper if heavily clogged |
| Full disassembly + heatsink removal | Complete cleaning + thermal repaste | Requires tools and skill; voids warranty if done incorrectly |
| Keyboard compressed-air clean | Removes key debris | Doesn't address internal cooling |
| Professional BAYAS service | Full internal clean + repaste + test | Best result; BDT 1,500–3,000 at your home |
For heavily clogged laptops (fan constantly at max, frequent shutdown), disassembly is required — the bottom panel, fan, and heatsink need to be removed, cleaned, and repasted. BAYAS technicians carry thermal paste and do this at your home in 45–90 minutes.
What Does a Professional PC Cleaning Service in Dhaka Cost?
| PC Cleaning Service | BAYAS Price (BDT) | What Is Included |
|---|---|---|
| Desktop deep clean (home visit) | 1,500 – 2,500 | Case interior, heatsink, fans, cable tidy — thermal repaste included |
| Laptop deep clean (home visit) | 1,800 – 3,000 | Full disassembly, heatsink clean, fan service, thermal repaste, reassembly + test |
| Office PC batch clean (per unit, 3+) | 1,200 – 1,800 per PC | Same service, bulk visit |
| Thermal repaste only (no full clean) | 800 – 1,500 | CPU/GPU compound replacement, temperature test before + after |
| Home visit + diagnostic only | 700 – 1,200 | Credited toward cleaning if you proceed |
Price note: These are BAYAS 2026 rates. All prices include the home-visit fee, compressed air, and thermal compound. For offices with 3+ units, a single visit covers all machines — call 01712-644590 for a bulk quote.
After a professional clean, most customers see CPU idle temperatures drop by 15–30°C. A thermal repaste alone on a 2–3 year old laptop typically reduces peak temperatures by 10–20°C.
DIY vs Professional PC Cleaning — When to Call BAYAS

| Fan noticeably louder than 3 months ago | ⚠️ Partial — blow vents only | Recommended within 4 weeks |
| PC shutting down under load | ❌ No | Yes — same week |
| CPU temperature above 85°C at idle | ❌ No | Yes — urgent |
| Laptop, any symptoms | ❌ No — too risky without tools | Yes |
| Desktop last cleaned over 18 months ago | ❌ DIY inadequate | Yes — thermal repaste needed |
| Office with 5+ PCs in dusty workspace | ❌ | Yes — schedule monthly contract |
| Gaming PC with liquid cooling | ❌ | Yes — coolant check needed too |
How Often Should You Clean Your PC in Dhaka?
The right cleaning frequency depends on your environment:
| Environment | Recommended Cleaning Interval |
|---|---|
| Air-conditioned, sealed apartment, no pets | Every 12 months |
| Normal Dhaka apartment (fan AC or no AC) | Every 6–8 months |
| Near a construction site or unpaved road | Every 3–4 months |
| Shop, market, or industrial workspace | Every 2–3 months |
| Home with pets (fur adds to dust) | Every 4–6 months |
| Gaming PC running 6+ hours daily | Every 4–6 months |
Dhaka seasonal tip: Schedule a professional clean in March–April (before the hot season) so your PC enters the 38–42°C summer months with maximum cooling capacity. A second clean in October (after monsoon) removes the humidity-clumped dust that accumulated during the rains.
How to Check Your PC Temperature in Dhaka — Free Tools
You don't need to open your PC to know if it's overheating:
- Download HWMonitor (free at cpuid.com) or HWInfo64 (free at hwinfo.com) — both work on Windows 10 and 11.
- Open the software and look for CPU Package temperature and GPU (Core) temperature.
- At idle (browser open, no gaming): safe range is 35–60°C for CPU, 30–55°C for GPU.
- At full load (gaming, video render): safe range is 70–85°C for most modern CPUs/GPUs.
- If idle temperature is above 75°C, or load temperature exceeds 90°C, schedule a cleaning immediately.

Frequently Asked Questions
How much does PC cleaning service cost in Dhaka?
Professional PC cleaning in Dhaka at your home costs BDT 1,500–2,500 for a desktop and BDT 1,800–3,000 for a laptop. BAYAS prices include compressed air, thermal paste, and the home-visit fee. The visit fee (BDT 700–1,200) is credited toward the cleaning cost if you proceed. WhatsApp 01712-644590 for an exact quote.
How often should I clean my PC in Dhaka?
Most Dhaka apartments need a PC cleaning every 6–8 months. Near construction or in dusty areas (Mirpur, Old Dhaka), clean every 3–4 months. Air-conditioned, sealed offices can extend to 12 months. The safest habit is to schedule a professional clean in March (before summer) and October (after monsoon).
Can I clean my PC with a vacuum cleaner?
No. A household vacuum generates static electricity that can permanently damage computer components — motherboard, GPU, RAM, and SSD are all at risk. Only use compressed air (available from computer shops in Agargaon or Multiplan Center) or call a professional for safe cleaning.
What is thermal repaste and why does it matter?
Thermal paste is the compound between your CPU/GPU chip and its heatsink. It fills microscopic gaps to conduct heat efficiently. Over 2–3 years, thermal paste dries out and cracks — reducing heat transfer by 15–30°C. Replacing it (thermal repaste) restores full cooling performance. BAYAS includes repaste in every full cleaning service.
How long does a professional PC cleaning take?
A desktop deep clean with repaste takes 45–75 minutes at your home. A laptop clean (full disassembly required) takes 60–90 minutes. Your PC is returned fully assembled and tested before the technician leaves.
Does BAYAS clean laptops at home in Dhaka?
Yes. BAYAS technicians carry all necessary tools (screwdrivers, spudgers, compressed air, thermal paste) for a full laptop disassembly, fan service, heatsink clean, and repaste — completed at your home. Book via WhatsApp 01712-644590.
What is the best time of year to get a PC cleaning in Dhaka?
March–April (before the hot season) is ideal — your PC enters summer with full cooling capacity. October (after monsoon) is the second best time — monsoon humidity causes dust to clump on fans and heatsinks. For heavily used systems or dusty areas, clean both times per year.
Will cleaning my PC make it faster?
If overheating is causing thermal throttling (the CPU slowing itself down to reduce heat), a professional clean can noticeably improve performance. In stress tests, BAYAS customers consistently see desktop CPU temperatures drop 15–25°C and performance benchmarks improve 10–20% on throttled systems after cleaning.
