How to Quickly Dry a Wet Mattress

February 27, 2024   By JM Carpiso

A wet mattress can be a nightmare for anyone. Whether it’s from a spilled drink, a leaky roof, or a bedwetting accident, a wet mattress can cause discomfort and even lead to mould growth if not properly dried. In this article, we’ll discuss the best techniques for quickly drying a wet mattress and preventing any further damage.

Why Is It Important to Quickly Dry a Wet Mattress?

A wet mattress can cause various problems if not dried quickly and properly. These include

  • Mould growth: A wet mattress provides the perfect environment for mould to grow, which can lead to health issues and damage to the mattress.
  • Odour: A damp mattress can develop a musty odour, making sleeping unpleasant.
  • Damage to the mattress: If left wet for too long, a mattress can become damaged and need to be replaced.
  • Discomfort: Sleeping on a wet mattress can be uncomfortable and disrupt your sleep.

Moisture Removal Techniques

Before you can begin drying your wet mattress, you’ll need to remove as much moisture as possible. Here are some effective moisture removal techniques:

The most common and effective way to remove moisture from a wet mattress is by using towels. Start by placing a towel on the wet area and pressing down firmly to absorb as much moisture as possible. Repeat this process with dry towels until no more moisture is being absorbed.


A vacuum can also be used to remove moisture from a wet mattress. Use the upholstery attachment and run it over the wet area, covering the entire surface. The vacuum will help to suck out any excess moisture from the mattress.

Baking Soda

Baking soda is known for absorbing moisture and eliminating odours. Sprinkle a generous amount of baking soda over the wet area and let it sit for a few hours. Then, vacuum up the baking soda and any remaining moisture.

Drying Techniques

Once you have removed as much moisture as possible, it’s time to dry the mattress. Here are some effective techniques for drying a wet mattress:

Air Drying

The most natural and effective way to dry a wet mattress is by air drying. Start by placing the mattress in a well-ventilated area, preferably outdoors in the sun. If this is not possible, you can also place the mattress in a room with a fan or open windows to promote air circulation. Make sure to flip the mattress periodically to ensure both sides are drying evenly.

Hair Dryer

A hairdryer can also be used to dry a wet mattress. Set the hairdryer to the lowest heat setting and hold it a few inches away from the wet area. Move the hairdryer back and forth over the wet spot until it is dry. Be careful not to hold the hair dryer too close to the mattress, which can cause damage.


If you have a dehumidifier, you can use it to dry a wet mattress. Place the dehumidifier in the room with the wet mattress and let it run for a few hours. The dehumidifier will help to remove excess moisture from the air, which will speed up the drying process.

Preventing Mould Growth

To prevent mould growth on your wet mattress, it’s essential to take the following steps:

  • Remove any excess moisture as soon as possible.
  • Use a fan or open windows to promote air circulation.
  • Use a dehumidifier to remove excess moisture from the air.
  • Sprinkle baking soda on the wet area to absorb moisture and eliminate odours.
  • Flip the mattress periodically to ensure both sides are drying evenly.
  • Place the mattress in direct sunlight to speed up the drying process if possible.

What Not to Do When Drying a Wet Mattress

When dealing with a wet mattress, there are a few things you should avoid doing to prevent further damage:

  • Do not use a high heat setting on a hairdryer, as this can cause damage to the mattress.
  • Do not use a heater to dry the mattress; this can also cause damage and maybe a fire hazard.
  • Do not use a steam cleaner, as the moisture from the steam can cause mould growth.
  • Do not use a blow dryer, as this can also cause damage and may take a long time to dry the mattress.

When to Replace Your Mattress

Knowing when to replace your mattress is essential for maintaining optimal sleep quality and overall well-being. As a general rule of thumb, mattresses should be replaced every 7-10 years, depending on factors such as mattress type, quality, and usage.

Signs that it may be time to invest in a new mattress include noticeable sagging or indentations, persistent discomfort or pain upon waking, and allergy symptoms like sneezing or congestion. By staying attuned to these indicators and prioritizing your sleep health, you can ensure that you’re getting the restorative rest you need for a healthier, happier life.

Signs of Mould and Mildew:

  • Visible dark spots or a musty smell mean you need a new mattress.
  • Mould and mildew can make allergies and breathing problems worse.
  • It’s important to deal with the issue right away.

Structural Damage:

  • Wet mattresses can lose support and become uncomfortable.
  • If you see sagging, lumps, or wear from water damage, get a new mattress.
  • A new mattress can help you sleep better and feel more supported.

Persistent Odours:

  • Even after drying a wet mattress, bad smells can linger.
  • Mould, mildew, or bacteria can cause stubborn odours.
  • If airing out the mattress doesn’t work, you may need a new one for a fresh sleep environment.

Allergic Reactions:

  • Mould, mildew, or dust mites in a wet mattress can cause allergies.
  • Symptoms like sneezing or skin irritation may worsen.
  • Switching to a clean, hypoallergenic mattress can help improve health and well-being.

Prolonged Moisture Exposure:

  • If your mattress stays wet for a long time, it can get damaged.
  • Moisture weakens materials and can grow mould and bacteria.
  • To avoid health risks, replace a wet mattress for a safe and comfy sleep space.

To Keep Or To Replace a Wet Mattress

A wet mattress can be a hassle, but with the right techniques, you can quickly dry it and prevent any further damage. Remember to remove as much moisture as possible before drying and to take steps to prevent mould growth.

On the other hand, if the mattress feels uncomfortable to sleep on and has a persistent smell, then it might be time to replace it for your own health.
