How To Wash Mattress Protector: Step By Step

Maintaining your mattress protector is a key step in keeping your actual mattress in top shape for years to come. Knowing how to wash a mattress protector the right way will also help keep your sleeping space fresh and hypoallergenic, as mattress protectors will end up with the sweat, oil, dirt, and more that can penetrate past your sheets. 

This guide offers a step-by-step approach on the cleaning process for mattress protectors (and our process is both effective and planet-friendly!). So, let's dive in and talk about how to boost your sleep hygiene while also extending your mattress's life.

Why Is It Important To Wash Your Mattress Protector?

Washing your mattress protector is vital for maintaining a clean and healthy sleeping environment. Over time, mattress protectors can harbor dust mites, bed bugs, allergens, and bacteria, which can impact your health, particularly if you have allergies or respiratory issues. Regular cleaning removes these irritants, ensuring the most hypoallergenic space possible. 

Additionally, cleaning prevents stains and odors from setting in, preserving the freshness and comfort of your bed. Over time, especially for those who may sweat a little more through the night, yellow discoloration can occur and will stain without frequent washing. For households with pets or children, washing is essential to manage pet hair, dander, and accidents. 

How Often Should You Clean a Mattress Protector?

How often you clean your mattress protector largely depends on your lifestyle and personal needs, but a general guideline is to wash it every one to two months. For those with allergies, strong body odor, pets, or young children, more frequent washing—every two to four weeks—may be necessary to manage allergens, pet dander, and unwanted smells.

Can You Wash a Mattress Protector in a Washing Machine?

Yes, you can wash a mattress protector in a washing machine, and it is often the most convenient and effective method for cleaning. Most mattress protectors, especially those made from cotton, are designed to withstand machine washing, but it's essential to check the care label for any specific instructions regarding water temperature and washer cycle settings. 

Typically, a gentle or delicate cycle with cold or lukewarm water is recommended to prevent damage to the protective components of the fabric. Using a mild, eco-friendly detergent will help maintain the protector's integrity while being kind to the environment. After washing, ensure the protector is thoroughly dried, either by air drying or using a low heat setting in the dryer, to prevent mold or mildew.  

How To Wash Mattress Protector: Step By Step

We covered the general process just above, but here’s your step by step with a few more tips to help you get the best out of each wash. 

Step 1: Read the Care Label

Before you begin, it is crucial to read the care label on your mattress protector. This label provides specific washing instructions tailored to the fabric and construction of your protector in particular. Some materials may require gentle cycles or specific water temperatures to help maintain the integrity of the fabric. There will also be variations in how to dry; while most should be safe for tumble drying on low, it’s also worth double-checking. 

Step 2: Pre-Treat Stains

If your mattress protector has visible stains, pre-treat them before washing them. Use a gentle, eco-friendly stain remover or a mixture of water and mild detergent. Apply it directly to the stained area and let it sit for about 10-15 minutes (follow the manufacturer’s directions if they recommend a shorter or longer treatment time). This step helps to break down stubborn stains, ensuring they are thoroughly removed during the wash cycle. 

Step 3: Choose the Right Washing Cycle

You’ll typically want to use a gentle or delicate cycle for your mattress protector to prevent any damage to the fabric, though again, make sure to check the care label. Use cold or lukewarm water, as hot water can cause shrinkage or damage to certain materials. Add a mild, eco-friendly detergent to the machine, avoiding harsh chemicals that could degrade the fabric or irritate sensitive skin. 

Step 4: Dry the Mattress Protector Properly

After washing, it's important to dry your mattress protector correctly. If the care label permits, you can tumble dry it on a low heat setting. Alternatively, air drying is an excellent option, especially for protectors made from natural fibers. Ensure the protector is completely dry before placing it back on your mattress to prevent any mold or mildew growth. Many mattress protectors will have a waterproof or water-resistant quality to at least one side of the fabric, so make sure this area in particular is completely dry. It can help to pull the protector out of the dryer in the middle of the cycle and shake it out to ensure no water is stuck in any folds. You may also opt to run the cycle again after shaking it out and “resetting” the protector’s position in your dryer. 

Can You Put a Mattress Protector in the Dryer?

Most mattress protectors can usually be put in a dryer with the tumble dry low cycle, but you should always double-check the care label in case line drying or using a no-heat tumble cycle is recommended. 

Typically, using a low heat setting is enough to prevent damage to the fabric or any waterproof layers. High temperatures can cause shrinkage or deterioration, reducing the protector's effectiveness. If air drying is recommended, lay the protector flat or hang it in a well-ventilated area to ensure it dries completely. 

What Should You Do If Your Mattress Protector Shrinks or Loses Its Waterproofing?

If your mattress protector shrinks or loses its waterproofing, there are a few steps you can take to address the issue. First, check if the care instructions were followed correctly, as improper washing or drying can lead to these problems. 

  • If the cotton protector has shrunk, gently stretching it while damp may help restore some of its original size. 
  • For lost waterproofing, you may want to try applying a fabric-safe waterproofing spray to restore its protective qualities. 

However, if these solutions do not work and the protector no longer fits or functions effectively, it may be time to invest in a new one. 

Consider the Miracle Made® Mattress Protector, renowned for its advanced waterproof technology and durable construction. This protector not only offers superior protection against spills and allergens but also ensures a comfortable and hygienic sleeping environment, making it a worthwhile addition to your bedding essentials. Plus, its silver-infused fabrics help prevent up to 99.7% of bacteria growth, helping to keep things cleaner for longer!

The Bottom Line

Keeping your mattress protector clean and in good shape is a straightforward yet powerful way to ensure your sleeping environment is both healthy and comfortable (and it helps extend the life of both your mattress and the protector, itself!). If you find that your current protector isn't cutting it anymore, it might be time to consider an upgrade (most experts recommend replacing these every few years as the protective qualities break down with wear and tear over time). 

Whether you're dealing with spills, pet hair, or just the usual wear and tear, regular cleaning and care is key, so take the time to wash your mattress protector about once a month!
