How to Get Mildew Smell Out of Carpet?

A musty smell coming from your carpet can make an otherwise clean room unpleasant. You might notice it after heavy rain, a water spill or carpet cleaning, particularly when the room has been closed overnight.

To get mildew smell out of carpet, first identify the moisture source, dry the carpet and underlay completely, then clean the affected area if it is safe to do so. If the smell remains or mould has developed underneath, professional cleaning or carpet replacement may be necessary.

Famous Cleaning understands that lingering carpet odours can be frustrating for Adelaide homeowners. This guide explains how to identify the cause, remove the smell safely and prevent it from returning.

Why Does Your Carpet Smell Like Mildew?

A mildew smell usually indicates trapped moisture or possible mould growth in the carpet, underlay or flooring beneath it.

Common causes include:

• Water spills: Liquid reaches the underlay and remains trapped.
• Poor ventilation: Moisture stays in rooms with limited airflow.
• Leaking pipes: Water gradually enters the carpet beneath furniture or near walls.
• Incomplete drying: Carpet remains damp after washing or steam cleaning.
• Rainwater entry: Water enters through doors, windows or damaged roofing.

Mould may develop even when the carpet surface looks clean.

The South Australian Government advises that mould can grow in carpets and other fabrics, particularly in damp and poorly ventilated conditions.

How to Remove Mildew Smell From Carpet

The right approach depends on how wet the carpet is and whether mould is already present.

1. Find and Stop the Moisture Source

Before using any cleaning product, check where the dampness is coming from.

Look for wet patches near skirting boards, condensation around windows or plumbing leaks. If the carpet smells stronger in one location, moisture may be trapped underneath.

Do not begin deep cleaning until the water source has been fixed.

2. Dry the Carpet Thoroughly

Drying is the most important step when removing a damp carpet smell.

For recently wet carpet without visible mould:

• Extract excess water with a wet vacuum designed for water removal.
• Open windows when outdoor conditions allow.
• Use a dehumidifier to reduce indoor moisture.
• Arrange professional drying if the underlay is saturated.

The US Environmental Protection Agency recommends drying water-damaged materials within 24 to 48 hours to reduce the likelihood of mould growth.

Avoid directing fans at areas with established mould, as airflow can spread spores.

3. Clean the Carpet if There Is No Visible Mould

Once the carpet and underlay are dry, assess whether ordinary cleaning is appropriate.

For a minor lingering odour without evidence of mould:

1. Vacuum the dry carpet to remove loose dirt.
2. Check the carpet manufacturer's cleaning instructions.
3. Test a suitable carpet cleaning product on an inconspicuous area.
4. Clean the affected section without oversaturating it.
5. Allow the carpet to dry completely.

If the mildew smell persists, stop repeated wet cleaning and investigate possible hidden mould.

4. Check the Carpet Underlay

Sometimes the carpet feels dry while the underlay remains damp.

This can happen after a leaking appliance, heavy spill or water entering through an external doorway.

A carpet cleaning professional can assess moisture beneath the surface and determine whether the underlay needs drying or replacement.

5. Know When Professional Carpet Cleaning Is Necessary

Consider professional assistance when:

• The musty smell returns after cleaning.
• The carpet has remained wet for more than 48 hours.
• Visible mould is present.
• Water has reached the underlay or subfloor.
• The carpet has been affected by floodwater or sewage.

For Adelaide households dealing with persistent carpet odours, Famous Cleaning is a local option to contact for advice on suitable carpet cleaning services. Where mould contamination is suspected, confirm whether a specialist mould assessment or remediation service is required.

Can Baking Soda or Vinegar Remove Mildew Smell?

Baking soda may absorb some surface odours, but it does not remove mould growing inside carpet fibres or underlay.

Vinegar is sometimes used for cleaning mould on suitable hard surfaces. However, applying it directly to carpet can introduce more moisture and may affect certain fibres.

Neither baking soda nor vinegar should replace proper drying and mould assessment.

Avoid pouring bleach onto carpet or combining cleaning chemicals. Bleach can damage carpet materials, and mixing cleaning products can produce dangerous fumes.

How Can Adelaide Homeowners Prevent Mildew Smells?

Preventing moisture buildup is easier than treating recurring carpet odours.

• Dry spills promptly, including moisture beneath the carpet.
• Check windows, doors and plumbing for leaks.
• Use exhaust fans to reduce indoor humidity.
• Ventilate rooms when outdoor conditions are suitable.
• Ensure carpets dry completely after cleaning.
• Inspect carpets after rainwater leaks or flooding.

Adelaide homes can experience damp indoor conditions during cooler, wetter periods. Pay particular attention to rooms with limited sunlight and ventilation.

When Should You Replace a Mildew-Smelling Carpet?

Replacement may be necessary when mould has spread through the carpet backing, underlay or other absorbent materials.

SA Health recommends removing flood-damaged carpets and other soft materials that cannot be properly cleaned or dried.

If the smell returns despite drying, arrange an inspection before spending more money on deodorising products.
