Keeping your topper clean is a great way to make sure your allergies stay away and your topper has a long lifespan!

Memory foam toppers need to be regularly cleaned. This can be done by pre-treating them against dust, stains and odours before washing the topper with detergent and water. The final step is to allow the topper to air dry completely.

A clean topper is comfortable and smells great. We show you everything you need to know to keep your memory foam topper lemony fresh!


The Basics Of Cleaning A Memory Foam Topper

Who needs another chore? Nobody, to be honest. But unfortunately, our beds play a huge role in our health and well-being. It is the place where our bodies reboot after a hectic day. Unfortunately, when a memory foam topper is not clean, it can cause allergies to flare up, asthma to become worse and bacteria can also take hold. 

Now that you know why it is important to spruce up that topper on a regular basis, here are the basic steps that you can expect.

  1. Remove the topper from the mattress and bed.
  2. Clean the dust and dirt with a vacuum cleaner.
  3. Treat stains and odours.
  4. Apply a cleaning product. 
  5. Wash the memory foam topper.
  6. Thoroughly allow the topper to air dry.

How Often Should I Clean My Memory Foam Topper?

The good news is that you do not need to perform a “deep clean” every day or week. If you keep things under control, you only need to wash your topper every few months. You can lengthen the time by treating spills and stains as soon as they happen and also by vacuuming your topper whenever you do the carpet in the bedroom or when you vacuum the mattress. 

Here are the best Eve mattresses reviews.


Remove The Topper From The Mattress And Bed

Take the topper off the mattress and move it to a large flat surface. A table or countertop is perfect. If your topper has a removable cover, then take it off and pop it into the washing machine.

Clean The Dust And Dirt With A Vacuum Cleaner

You can always use a brush and a dust-pan for this task. However, a vacuum cleaner will save you a lot of time! Should you choose to use a vacuum cleaner, remember to use the upholstery nozzle to suck away dirt and bits that might have accumulated in small creases. You want to remove as much debris as you possibly can. This will ensure that the washing and rinsing stage of cleaning your topper will go smoother. 

Do both sides and make sure that you clean the topper thoroughly. This is to get rid of the deeper dust, mites, and other particles. 

How To Treat Stains On Your Memory Foam Topper

Treating stains before the main washing step is essential. Have you ever washed something and the stains were still there afterwards? It is a disheartening feeling. But pre-treating your memory foam topper for stains will work well to prevent stains from surviving the entire cleaning process. 

A popular way to treat stains is the vinegar method.

Step 1: Gather an empty spray bottle, undiluted vinegar, water, baking soda and a clean cloth.

Step 2: Add ¾ cup water and ¼ cup vinegar inside the spray bottle.

Step 3: Gently shake the bottle to mix the solution.

Step 4: Spray the solution on the stain and gently try to remove the stain.

Step 5: If it’s a tough stain, spray the spot lightly and sprinkle baking soda over the area. 

Step 6: Allow the vinegar and baking soda to sit for an hour or two.

Step 7: Remove the vinegar and baking soda with the cloth. 

Step 8: Allow the moist area to air dry (only if you are not going to continue with the cleaning until the next day).

How To Treat Odours On Your Memory Foam Topper

The sad fact is that memory foam absorbs odours. It can be urine, that neighbourhood barbeque’s smoke, cigarette smoke, and even household cooking smells. Needless to say, sleeping on a topper that reeks cannot be pleasant. You will definitely struggle to fall asleep. Luckily, odours are pretty easy to remove from memory foam. 

Step 1: Gather a box of baking soda, the vacuum cleaner, and some patience. 

Step 2: Place the topper somewhere where it will not be disturbed for a while (especially if you have small children and nimble cats)!

Step 3: Liberally sprinkle the baking soda over the surface of the topper. 

Step 4: Leave the topper like that for preferably overnight. 

Step 5: Use the vacuum cleaner to thoroughly remove all traces of the baking soda. 

Step 6: Repeat the process with the other side.

Apply A Cleaning Product

Purchase a good quality cleaning product – but preferably the kind that comes in a spray bottle. This will make applying the cleaning solution a lot easier. You can follow the instructions on the bottle to complete cleaning your memory foam topper. 

Alternatively, you can mix ⅔ cup water with ⅓ liquid laundry detergent in a spray bottle. Gently shake the bottle and lightly spritz the surface of the memory foam topper. Allow the detergent to sit for at least an hour.

Wash The Memory Foam Topper

The next step is to remove the cleaning product. You can do this in two ways. You can either lightly wipe the surface of the topper with a damp cloth and repeat until all the detergent is gone. Or if you want to really give your topper a thorough cleansing, take it outside and rinse it with the hose pipe. Make sure that you get all the suds out of the foam by repeating the rinse as many times as you need to. 

Thoroughly Allow The Topper To Air Dry

This is another essential step. But not always the easiest! It can be really hard to tell when a memory foam topper is completely dry on the inside. Choose a day that does not have rainy weather or high humidity (this will only draw out the drying process and possibly even cause mould to develop). 

Leave the foam topper on a surface for several days and check on its progress every so often. Wipe the surface as soon as you notice any moisture forming. Also, turn the topper multiple times a day. You can also raise the topper a bit by placing something along the edges. This will allow airflow underneath the topper and speed things up.

My journey into the world of sleep came about through living in several properties over my lifetime and always seeming to have the worst luck with neighbors. All but one have been extremely noisy and very inconsiderate. What this made me realize early on, was that the little sleep my neighbors allowed me to get needed to be of great quality. So I started to learn all about sleep, and what helps people get the best quality sleep possible.
