Introduction
Plaster ceilings look elegant—but they collect dust fast in Malaysia’s humid weather.
Cleaning plaster ceilings is essential for maintaining a clean, healthy home. But doing it wrong can lead to peeling paint, water damage, or even cracks. With the right techniques and tools, you can keep your ceiling spotless without affecting the finish.
Why Cleaning Plaster Ceilings Needs Extra Care
Unlike tiles or cement, plaster is porous and delicate
Painted plaster ceilings, especially those with cornices or moulding, are prone to damage if scrubbed too hard or cleaned with the wrong chemicals. Moisture can seep into the plaster, leading to stains or weakening the material over time.
Tools and Materials You'll Need
Microfiber cloth or soft sponge
Mild dish soap or vinegar
Spray bottle
Extension pole with a duster
Step ladder
Optional: baking soda for stubborn stains
Optional: dry mop with a swivel head
Step-by-Step Guide to Clean Plaster Ceilings
Follow these gentle but effective steps
Dust first: Use a microfiber duster with an extension pole to remove loose dust and cobwebs.
Prepare a cleaning mix: Combine warm water with a small amount of dish soap or vinegar in a spray bottle.
Test a small spot: Spray lightly on a hidden area and dab with a sponge to ensure no paint damage.
Wipe carefully: Lightly spray the area and use a soft sponge in circular motions—never soak the surface.
Dry immediately: Use a dry cloth to blot any moisture and speed up drying.
How to Handle Stains and Mold
Target trouble spots without harming the paint
Grease stains: Use a baking soda paste (baking soda + a little water) to gently lift stains.
Mold spots: Mix vinegar with water (1:1) and apply using a sponge. Do not scrub—just press and blot.
Avoid bleach: It’s too harsh for painted plaster and can cause discolouration.
What to Avoid When Cleaning Painted Ceilings
Using abrasive sponges or scrubbers
Applying too much water or soaking the surface
Harsh chemical cleaners like bleach or ammonia
Leaving moisture to air-dry (this can damage paint or lead to mold)
Maintenance Tips for Malaysian Homes
Clean every 2–3 months to avoid buildup from humidity, dust, and smoke.
Install exhaust fans in dining or cooking areas to reduce ceiling grime.
Use dehumidifiers or air purifiers to lower moisture and airborne particles.
Paint with mold-resistant ceiling paint if you're planning a repaint.
DIY Natural Cleaning Solutions
Go green and save money
Lemon juice + baking soda: Good for mild stains and a natural fresh scent.
White vinegar + water: Antibacterial and safe for painted surfaces when used moderately.
Essential oil + water spray: Add lavender or tea tree oil for mold prevention and odour control.
When to Repaint After Cleaning
Know when it’s time for a fresh coat
If cleaning reveals cracks or bubbling paint, it may be time to repaint.
Wait at least 24–48 hours after cleaning to ensure surface is dry.
Use a ceiling-specific, moisture-resistant paint to extend the repaint cycle.
Ceiling Types to Know Before Cleaning
Know your ceiling before you scrub
Plasterboard/gypsum: Common in modern homes, needs soft cleaning.
Lime plaster: Older homes may use this—it's more fragile.
Textured/plaster of Paris (POP): Be extra careful not to damage designs or trim.
Did You Know?
Malaysia’s humidity can cause even high-quality ceiling paint to bubble or peel if moisture builds up.
Regular dusting alone can extend your paint life by up to 30%.
Ceiling stains are common near air vents or light fixtures—these areas need more attention.
Conclusion
Cleaning your plaster ceiling doesn’t have to be stressful or risky. With the right approach, you can safely maintain its beauty without damaging the paint. Stick to gentle methods, avoid excessive water, and clean regularly to keep your home fresh and stylish.
