Curtains are one of the most overlooked parts of home cleaning, yet they absorb dust, allergens, odours, moisture, and pollutants every single day. While they may appear clean from a distance, the fabric quietly collects debris that affects indoor air quality, room freshness, and even allergy symptoms. That’s why regular care is essential — not just occasional washing. Understanding exactly how often to clean your curtains can feel confusing, especially with different fabrics and households having different needs. This seasonal curtain-cleaning calendar breaks down what to do and when, so your home stays cleaner, healthier, and more comfortable all year round.

Curtains trap allergens and airborne particles more than most homeowners realize. They act as filters, pulling in dust from open windows, smoke from cooking, pet hair, and even fine pollution from outdoors. The longer the fabric goes without proper cleaning, the harder it becomes to remove buildup. Key reasons you shouldn’t delay:

• Dust mites increase with humidity and warmth
• Pollutants from outside air cling to fabrics
• Odours from cooking and pets settle deep into fibres
• Mould spores can develop in damp conditions
• Heavy fabrics trap more debris than lighter ones
  

Spring is the ideal time for a full, professional deep clean. Pollen levels are high, windows stay open longer, and allergens settle quickly on curtain material. A thorough clean helps reset your home after winter and prepares it for warmer months.

Recommended spring actions:

• Professional curtain cleaning for all rooms
• Spot treatment for stains
• Removal of trapped allergens
• Refreshing heavy fabrics like blackout or lined curtains
  

In summer, curtains frequently absorb moisture from humidity and odours from increased cooking and activity. Regular maintenance prevents mildew and keeps the room smelling fresh. What to do in summer:

• Light vacuuming once a month
• Air out curtains outdoors when possible
• Check for signs of moisture or mould
• Wipe curtain rods and surrounding areas
  

Autumn brings dust, dry air, and indoor heating — all of which contribute to fabric buildup. A mid-year deep clean is wise, especially for households with pets or allergies. Autumn care checklist:

• Professional cleaning for living rooms and bedrooms
• Removal of smoke, odours, and summer humidity residue
• Inspection for dust accumulation in pleats
• Refresh lightweight curtains before winter
  

During winter, windows remain closed, and heating systems push dust around the home. Curtains don’t get as dirty, but they do trap indoor air contaminants. Winter maintenance tips:

• Vacuum every 4–6 weeks
• Spot-clean unexpected stains
• Keep curtains dry to avoid condensation-related issues
