How to clean a mattress

Why regular mattress cleaning is essential 

Mattresses have a porous, permeable structure, which makes them ideal environments for microscopic particles to accumulate.

Dust mites, bacteria, viruses and pollen particles can permeate mattress fibres, while skin cells, hair and natural perspiration can settle into the layers of your mattress over time. Not only can this impact sleep quality, but it can also trigger allergic reactions, asthma symptoms or skin conditions.

How to clean a mattress effectively

Mattress cleaning can involve both dry and wet methods, depending on the type of stain or dirt you want to target. Dry cleaning effectively removes dust and other dry particles, such as those mentioned above, while wet cleaning with steam or water can address specific stains, spills and deeper contaminants.

1. Wash sheets regularly

Changing and washing your sheets regularly is the first line of defence in keeping your mattress clean. To eliminate dust and allergens, wash mattress sheets, duvet covers and pillowcases at 60°C or above. 

2. Use a mattress protector

A high-quality mattress protector helps prevent dust, particles and allergens from permeating your mattress. It’s also easier to wash a mattress protector than your whole mattress, and it can add another level of comfort to your bed.  

3. Vacuum your mattress monthly

Monthly mattress vacuuming removes surface dirt and particles before they can penetrate deeper. Cordless vacuum cleaners are ideal for cleaning mattresses because they offer optimal manoeuvrability. Select a high-performance device with enough suction power for thorough particle extraction. 

Dyson’s fully sealed HEPA filtration traps microscopic particles and allergens and expels cleaner air, while specialised upholstery attachments effectively remove particles without sticking to the mattress fabric.

4. Clean hard-to-reach areas with precision attachments

Cordless vacuum attachments access seams, edges and structural elements on your mattress. These areas can accumulate significant quantities of dust and allergens, so precision tools are required for thorough cleaning.

5. Rotate the mattress to manage moisture

Turn your mattress regularly and vacuum all sides to maximise allergen extraction. Rotating and airing your mattress can help prevent trapped moisture, which can lead to mildew or mould if left unchecked for too long. Some mattresses can also be flipped for a fresh sleeping surface. Check with the manufacturer before flipping your mattress.

Dyson air treatment includes a range of air purifiers, hygienic humidifiers and powerful fans and heaters designed to maintain an optimal climate. Find the right air purifier for you.

6. Address blood and urine stains immediately

Some biological stains, including blood or urine, should be treated as soon as possible to avoid contamination. For blood or urine stains on a mattress, absorb excess moisture with a clean cloth, then apply warm or sparkling water and gently blot until the stain dissolves. 

For dried-on stains, combine citric acid and salt and apply the mixture to the stained area. Leave the salt substance to absorb stains and odours for a minimum of one hour before dabbing and vacuuming away. Make sure the area is completely dry before replacing the bed sheets. 

7. Bleach pigmented stains

Tea, coffee and red wine stains contain compounds that can be dissolved into colourless substances using the right cleaning agents. Apply bleach-based products sparingly and methodically, as they can discolour the dyes in your mattress fabric.

8. Treat perspiration stains with baking soda

Sodium bicarbonate (baking soda) is an effective treatment for perspiration stains and neutralises odours. Apply a few tablespoons of baking soda directly onto the affected areas, allowing at least five hours for it to absorb before vacuuming. 

How to disinfect your mattress 

These standard cleaning procedures are generally enough for mattress maintenance. However, you can create a natural disinfectant by combining equal parts water and white vinegar in a spray applicator. Strong disinfectants are not recommended, as they may compromise the integrity of the material.  

How to clean stains from your mattress

Identifying the cause of the stain is more important than addressing its appearance. Yellowish mattress stains are often caused by urine or perspiration, with each requiring a different cleaning approach. Urine responds to sparkling water or citric acid, while perspiration is best treated with sodium bicarbonate.

How often should you clean your mattress?

Mattress cleaning can vary depending on the material, construction and environment. Monika Stuczen, senior microbiologist at Dyson, recommends cleaning the mattress thoroughly every six months, once during spring cleaning and once in October, at the end of dust mite season.

When should you replace your mattress?

Worn mattresses can contribute to sleep discomfort and spinal strain. Standard mattresses should be replaced around every five to eight years, while premium models may last more than ten years. 

For hygiene purposes, it’s recommended to replace your mattress immediately if stains persist despite cleaning or if mildew and mould are present. 

Engineering superior sleep environments

Effective mattress maintenance requires a high-performance vacuum cleaner and household cleaning agents. These techniques help target specific stains and odours and can also be used as preventative measures for a cleaner, fresher sleep surface.
