Your mattress is a big investment. It’s a major piece of furniture you will most likely keep for the next 8-10 years. When you spend an average of seven hours a night for 10 years, sitting, lying, and sleeping on your mattress, it is bound to get a little dirty. Fortunately, there are ways to clean your mattress and maintain it for years to come.

You should clean your mattress at least every six months, especially if you suffer from allergies or have pets. Cleaning your mattress is easy to do. Simply follow our guide with eight easy steps to keep your mattress looking like new year-round.

Step One: Gather Your Mattress Cleaning Supplies

The first step to a clean mattress is to get the right cleaning supplies. Proper cleaning supplies will make a big difference, as well as make cleaning go much faster.

  • Vacuum
  • Laundry detergent
  • Baking soda
  • Cleaning cloth
  • Enzyme cleaner or dish soap

Step Two: Strip the Bed and Wash all Bedding

Once you gather your cleaning supplies, your next step is to clean all the bedding. Remove all sheets from the bed, including the comforter, fitted sheet, and any blankets. Make sure to remove the pillow cases as well. Toss them into your washing machine to clean them of any dirt, grime, or stains.

Wash your pillows, too. Keep in mind, your pillows may require a different method of cleaning, so follow the directions on the tag.

Once your bedding has been cleaned, make sure to properly dry them. Damp bedding could develop mold or other bacteria you do not want on you or your mattress.

Step Three: Vacuum Your Mattress

While washing your bedding, you can start vacuuming your mattress. Using your upholstery attachment, vacuum your mattress thoroughly. Vacuuming your mattress will help get rid of most of the dirt, dust, and dander that has collected on it. Vacuuming is important to do before using water and cleaning solutions because it will help remove any dirt or grime that could be set in place with water.

Make sure when vacuuming, to go over the side you sleep on several times, as well as the edges.

Step Four: Spot Clean Your Mattress with Stain Remover

After you vacuumed your mattress thoroughly, it is time to spot clean. The type of stain remover you will use will depend on the type of stain. For general stains, like dirt and grime, a standard stain remover should work. For urine, vomit, or sweat stains, an enzyme cleaner or hydrogen peroxide will help break down the stains and make it easy for you to remove them.

If you do not have access to stain remover or enzyme cleaner, dish soap works well to remove most stains. Also, hydrogen peroxide can remove blood stains with ease, so it might be a good product to have on hand.

It is important to not use too much cleaning solution when trying to remove stains. Less is more when starting out. Here are four steps for spot treating a stain:

  1. Apply a small amount of cleaning solution to a rag. Then gently pat the stain with the rag.

2. Let the solution sit for a few minutes. Then gently pat the area with a clean cloth.

3. Add cold water to another clean rag. Then pat the area with a wet rag.

4. Repeat steps 1-3 if stain is still present.

Following these steps will assure you do not add too much cleaning solution, which could take a long time to dry and potentially damage your mattress.

Step Five: Sprinkle Baking Soda Over the Entire Mattress

After you allow any treated areas to dry, sprinkle baking soda over your mattress. Baking soda acts as a natural deodorizer, helping to remove any odors.

When applying the baking soda, gently pat it into your mattress, then allow it to sit for a while. We recommend letting the baking soda sit for at least 15 minutes, preferably for several hours. This will ensure the baking soda has plenty of time to lift any odors out of your mattress.

Step Six: Vacuum Again

After you let the baking soda sit for a while, you then need to run your vacuum over the mattress again with the upholstery attachment. Pay close attention to any and all mattress seams, carefully vacuuming up all of the baking soda.

It may help to go over your mattress a couple more times with the vacuum, to make sure you have vacuumed up all the baking soda.

Step Seven: Air Out the Mattress

Now that you vacuumed, spot treated, and deodorized your mattress, it is time to let it air dry. This is an extremely important step in the cleaning process. Airing out your mattress will allow it to dry properly and help clear it of any leftover odors. Open your bedroom window for extra ventilation, or move your mattress to direct sunlight if possible.

Always make sure your mattress is properly dry before replacing the bedding. If your mattress is still damp while the bedding is on, it could prevent your mattress from drying completely and create mildew. Mildew could cause stains, unpleasant odors, and damage to your mattress.

Step Eight: Flip the Mattress

After you aired out your mattress, you will want to flip it over and repeat steps 1-7 for the other side. Cleaning your mattress may require a good amount of time from your day, but it will save you money in the long run and make sure you get the most life out of your mattress.

With a Purple mattress, you can skip step eight. Purple mattresses are designed with the patented GelFlex™ Grid technology, which requires the mattress to stay upright. We advise that you rotate a Purple mattress every three to four months. This will help maintain its support and structure, and prevent too much wear on one specific side.

Additional Considerations

Protect the Mattress

A mattress protector will also help keep your mattress clean. Mattress protectors work to keep dirt and stains off your mattress. Although we still recommend cleaning your mattress every few months, a mattress protector will help make the process easier by preventing most stains and requiring less vacuuming.

Remember to regularly clean your mattress protector, too. They are easy to clean and will help keep your mattress looking like new for years to come.

Mattress Stains

Blood stains: are difficult to remove from bedding and mattresses, but with the right tips and tools, you can remove these types of stains without too much difficulty. The key to removing blood stains is to use cold water—never warm or hot—and hydrogen peroxide. It may take a few attempts to completely remove the stain, but if you follow our tips, you can get rid of unwanted blood stains.

Urine Stains: require a good enzyme cleaner to break down the stain. By adding a small amount of enzyme cleaner to the stain, letting it sit, and then gently patting at the stain, you should have little difficulty removing the stain. If the stain doesn’t lift the first time, repeat the process until it does.

Sweat Stains: Similar to urine stains, sweat stains are easily removed with either hydrogen peroxide or a good enzyme cleaner. Add a small amount of cleaning solution, let sit, and gently pat the stain dry. If necessary, repeat the process until the stain is gone.

Can I Wash My Purple Mattress Cover?

Since the white mattress cover (the puffy cover that says Purple) has a zipper, you have the ability to entirely remove it. This may tempt you to take it off and machine wash it. PLEASE DON’T.

The cover has an incredible amount of spandex so you get the full benefits of Purple. When it goes through the washer and dryer, the mattress cover will shrink.

Your mattress and bedding play a big role in how you sleep. Caring for your mattress properly by cleaning it regularly will ensure your mattress lasts a long time, and you continue to get the proper sleep you need.

When it does come time to get a new mattress, Purple has the perfect fit for you. Purple delivers quality sleep straight to your bedroom.
