Cleaning a memory foam mattress does not have to be a difficult task, even if it seems daunting. No matter how hard you try to keep it in great condition, your memory foam mattress will need to be cleaned from time to time. It’s inevitable that the mattress will get dirty through use, so we are here to ensure you know exactly how to clean your memory foam mattress.

In most cases, we would suggest using a damp sponge or cloth, but you need to first consult with the manufacturer’s care guide. Here we will take a look at some tips to clean your memory foam mattress to keep it fresh and clean.

How to Clean Memory Foam Mattress

Below, we will go through eight simple steps that allow you to clean your mattress, freshening it up and removing stains. If you are concerned or unsure about the cleaning of your mattress, contact the mattress manufacturer first.

1. Check Cleaning and Care Instructions

Each mattress manufacturer will have its own set of care instructions, so it is best to check these before moving forward with any other steps. The reason for this is that you may find the manufacturer has recommended a cleaning method for your mattress.

2. Wash the Mattress Cover

If your mattress comes with a removable cover, ensure that it is clean. Most mattress covers can be washed in a washing machine, but if it can’t be, follow the next steps to spot clean your mattress.

3. Clean Any Stains With Laundry Detergent

Ensure that, when cleaning your mattress, you avoid getting it too wet. This can damage the memory foam filling. Instead, spray a light mist of lukewarm water onto the mattress and dab the stain with a cloth.

If you choose to use laundry detergent, make sure it is a gentle brand that does not use harsh chemicals as this can also break down the foam.

4. Don’t Allow the Stains to Dry

When possible, tackle stains as soon as they happen and are still wet, as this is when it is easiest to deal with them. Clean your mattress with a damp sponge or cloth to soak up the moisture. Then, open your bedroom windows and let your mattress air-dry for a few hours before placing the bedding on again.

5. Vacuum the Mattress

Each week, when you wash your sheets, gently vacuum the mattress to remove dust, dirt, dead skin cells, hair, and pet dander. This will give you a nice, clean surface to put the clean bedding onto. Additionally, if you suffer from allergies, this will be very beneficial.

6. Allow the Mattress to Air-Dry

Once you have cleaned your memory foam mattress, you should let it air-dry. This prevents the mattress from being damp for a prolonged time. It is vital to ensure your mattress is totally dry before putting your bedding on again.

7. Sprinkle Baking Soda

If you want to keep your memory foam mattress smelling fresh and clean, sprinkling baking soda on the surface can do wonders. Ensure you cover the entire mattress in a light layer of baking soda, then leave it for 4 – 6 hours. Vacuum the baking soda from the mattress and enjoy an odorless sleeping experience!

8. Wash Your Bedding and Sheets Weekly

Washing your sheets and linen regularly will kill dust mites and bacteria, keeping your mattress cleaner and healthy for a long time. Ensure you wash your bedding on the highest heat advised. It is also advised that you tumble dry your linen at a higher temperature as this helps make it smell fresh.

Can Memory Foam Mattresses Be Steam Cleaned?

Most manufacturers will advise against steam cleaning your memory foam mattress, as moisture and heat from the steam cleaner can cause damage to the mattress construction and affect the foam’s integrity. Additionally, using a steam cleaner may impact the warranty for your mattress.

If you are trying to remove a particularly tough stain, use the steps above. Air your mattress regularly and vacuum dust, dirt, hair, and dander each week when you change your linen and sheet.

Can Memory Foam Pillows Be Washed?

No, they can’t. This is because washing them will damage the foam, which reduces the comfort and support they are meant to provide. Memory foam pillows will often come with a cover that can be removed and machine washed, so you can keep them as clean as you prefer.

Much like a memory foam mattress, check the care instructions that came with the pillow so you can see what to do when it comes to cleaning dirt or stains.

Keeping Your Memory Foam Mattress Clean

Once you have cleaned your mattress, you will want to keep it clean for longer. Here’s how:

Vacuum the mattress weekly

Each week, when you wash your linen and sheets, vacuum your mattress to remove dirt, hair, and skin cells.

Wash the cover and bedding often

Ensure that you wash your cover and bedding every week.

Open the windows often for ventilation

As regularly as the weather allows, open your windows to air out your room and mattress to eliminate odors.

Don’t let your pets sleep on the bed

If you are trying to keep your bed cleaner for longer, don’t let your pets sleep on the bed as they bring extra dirt, fur, and dander.

Don’t drink or eat on or in the bed

As the old saying goes – prevention is better than a cure. Prevent any spills or messes by keeping food and drinks out of the bed.
