Why Drying Clothes Indoors Is Feeding Mould in Your Home

Drying clothes indoors might feel harmless. It is convenient, especially during rainy days in Singapore. But this daily habit is one of the biggest reasons mould keeps appearing in bedrooms, living rooms, and even storerooms.

Many homeowners clean mould repeatedly without realising that their laundry routine is quietly feeding the problem.

Let’s break down why indoor drying causes mould and what you can do to stop it.

What Happens When You Dry Clothes Indoors

Wet laundry releases a large amount of moisture into the air. In Singapore’s already humid climate, this extra moisture has nowhere to go if windows are closed or airflow is poor.

As the water evaporates from clothes, humidity levels inside the room spike. That moisture settles onto walls, ceilings, furniture, and fabrics.

Once surfaces stay damp long enough, mould spores begin to grow.

Why This Is a Bigger Problem in Singapore Homes

In Singapore, indoor drying causes faster mould growth because:

• Humidity is already high year round

• Windows are often kept closed for aircon use

• Rainy periods reduce natural ventilation

• Many homes lack cross ventilation

• Clothes take longer to fully dry indoors

Even one load of laundry can raise indoor humidity significantly, especially in bedrooms or living rooms.

Where Mould Usually Appears After Indoor Drying

We often see mould forming in these areas:

• Walls near drying racks

• Ceiling corners above hanging clothes

• Behind furniture close to laundry areas

• Inside wardrobes near freshly dried clothes

• On curtains or blinds near windows

Homeowners usually notice mould weeks after changing their drying habits, not immediately.

Why Opening Windows Sometimes Is Not Enough

Many people try to fix the issue by opening windows occasionally. While this helps, it does not always solve the problem.

On rainy or humid days, outdoor air can be just as moist as indoor air. Without proper airflow, moisture still lingers inside the home.

Fans and dehumidifiers are often more effective than relying on windows alone.

Why Mould Keeps Returning Even After Cleaning

Wiping mould away removes what you see, but the environment stays the same. If clothes continue drying indoors without moisture control, mould spores will keep settling and growing again.

This is why mould often returns in the same spots after cleaning or repainting.

How to Dry Clothes Indoors Without Causing Mould

If outdoor drying is not possible, here is what actually helps:

• Use a dehumidifier while drying clothes

• Keep fans running to move air around

• Dry laundry in one designated area only

• Avoid drying clothes in bedrooms

• Remove dried clothes promptly

• Monitor humidity levels during rainy periods

Controlling moisture is the key.

How Sterng Can Help

At Sterng, we frequently handle mould cases linked directly to indoor laundry drying.

We inspect humidity levels, identify mould growth patterns, and treat affected surfaces with a proper mould-killing solution that kills mould at the root. Fogging is then used to neutralise airborne spores so mould does not resettle.

We also guide homeowners on safer indoor drying practices to prevent recurrence.

Final Thoughts

Drying clothes indoors may seem like a small habit, but in Singapore’s climate, it has a big impact. If mould keeps appearing in your home and you regularly dry laundry indoors, the connection is often stronger than you think.
