You spend roughly a third of your life in bed, which makes it one of the most-used spots in your home. While you might change your sheets regularly, your mattress protector quietly works underneath, catching sweat and all the little things you’d rather not think about. So it’s only natural to wonder: Can you wash a mattress protector? The answer is yes, and in fact, you should. The key is knowing the right way to clean it, which depends on the type of protector you own and how often it’s used. This article walks you through exactly that.
Key Takeaways:
- You can wash a mattress protector ideally every one to two months.
- Check the care label first, because different protectors (cotton, waterproof, bamboo, etc.) have different washing instructions.
- Use a gentle detergent and cold/warm water to avoid damaging the waterproof backing or fibers.
- Skip bleach and fabric softeners, as they can ruin the material or reduce the protector’s effectiveness.
- Air-drying or tumble drying on low heat will help keep your protector in shape and extend its lifespan.
Why You Should Wash Your Mattress Protector
Your mattress protector does a lot more than just cover your bed. It is a barrier between your mattress and everything life throws at it: sweat, body oils, dust mites, spills, pet dander, and whatnot! Over time, all of that builds up, potentially affecting your sleep quality.
Even though the protector is not directly exposed to your skin, it still traps moisture. Washing it regularly helps keep your bed fresh and more hygienic overall.
How Often Should You Wash a Mattress Protector?
See, there's no universal rule here, but we can give you some guidelines that work for most people:
-
Every month or two is fine if you're an average sleeper in a normal climate.
-
Every few weeks makes more sense if you're someone who sweats a lot at night, you live somewhere humid, or your pets have claimed half your bed.
-
Right away after spills. Well, this one's obvious. Don't let it sit, or you'll be dealing with stains and smells that really set in.
You don't want to go overboard, though. Washing it too often can actually wear out the waterproof layer faster. Just find a rhythm that works and stick with it.
How to Wash a Mattress Protector Properly
Let's look at how to wash mattress protectors the right way:
1. Check the Care Label
Reading tags is boring. But seriously, check it first. The manufacturer put those instructions there for a reason. They'll tell you what temperature to use, whether you can throw it in the dryer, and if there's anything specific you need to avoid.
2. Pre-Treat Stains (If Needed)
If there are visible stains (like sweat marks or spills), spot-clean them first. Use a mild detergent mixed with water or a gentle stain remover. Avoid harsh chemicals, as they can break down waterproof membranes.
3. Machine Wash on Gentle Cycle
Most mattress protectors can go straight into the washing machine, but not all of them. Always double-check the manufacturer’s care instructions before tossing it into the washing machine. Some protectors made with delicate materials, or those that include foam, might require hand washing or spot cleaning instead.
If yours is safe for the washer, use cold or lukewarm water (do not use hot water) on a gentle wash cycle. Add a mild detergent. Skip the bleach and fabric softener completely. Bleach is too harsh, and fabric softener can actually clog the breathable parts of the protector or interfere with its waterproofing.
4. Rinse Thoroughly
If your machine has an extra rinse option, use it. You want all that detergent out. Leftover soap can make the material stiff and reduce the lifespan of your mattress protector.
5. Dry It the Right Way
Air drying is your best bet. Just hang it up flat or drape it over a clothesline until it's bone dry. If you prefer the convenience of a dryer, stick to low heat. High heat can literally melt the waterproof backing, which kind of defeats the whole purpose.
Pro tip: Adding a couple of dry towels to the dryer can speed up the process and help the protector dry evenly.
Quick Tips to Keep Your Protector Fresher Longer
Let's have a quick look at some of the easy tips to keep your waterproof mattress protector fresh for longer.
-
Use a sheet on top: It reduces the frequency of washing the protector.
-
Let it breathe: When changing sheets, leave your bed uncovered for an hour to allow moisture to evaporate.
-
Have a spare: Keeping a backup protector makes laundry day easy.
The Bottom Line
Most people buy a mattress protector, put it on once, and basically forget it exists until they move or buy a new mattress. Well, that's a very big mistake, because this little layer is quietly doing a lot of work. It's keeping your expensive mattress from turning into a bacteria hotel and saving you from that awful moment when you realize a spill has soaked through.
Washing it regularly keeps your bed actually clean, not just looking clean. You'll sleep better when you're not lying on months of accumulated gunk. And the whole process takes maybe ten minutes of active effort - toss it in the washer, dry it on low, put it back on. That's about as low-maintenance as hygiene gets.
So yeah, wash your mattress protector. Your future self will appreciate it when you're not replacing your mattress five years earlier than you needed to.
Frequently Asked Questions
Most mattress protectors are machine washable, but it’s always best to check the mattress protector’s label before you start. Different materials have specific instructions. For example, cotton, bamboo, and waterproof materials may require slightly different settings.
To wash mattress protectors the right way, use cold water or lukewarm water on a gentle wash cycle. Add detergent (a mild, liquid laundry detergent works best). Avoid using bleach and fabric softeners, as they can damage the waterproof barrier or cause buildup over time.
If there are tough stains or body fluids, such as sweat or urine stains, spot-treat the area before washing. A simple mix of baking soda and water, or a small amount of hydrogen peroxide, can help lift stubborn stains and eliminate odors without harming the fabric.
Once washed, gently squeeze out excess water, but don’t wring it. This should be followed by drying. Most mattress protectors are safe to put in the dryer as long as you use a low-heat setting.
High temperatures or extreme heat can warp the waterproof materials, shrink the fabric, or reduce the effectiveness of the waterproof barrier. The good rule here is to tumble dry on low or use an air-dry cycle.
If you have time, air-drying is even better. Just make sure it’s completely dry before putting it back on your bed to prevent any trapped moisture.
A high-quality mattress protector ensures that bed bugs can’t easily infest your mattress. However, not all protectors are designed to be fully bed bug–proof.
Standard protectors act as a barrier against dead skin cells, dirt, and moisture, which is beneficial for general hygiene. But if you’re specifically trying to stop or get rid of bed bugs, you’ll need a mattress encasement rather than a regular mattress cover.
Encasements are zippered covers that completely seal your mattress. They are designed to trap any bed bugs inside and prevent new ones from getting in. So, while most mattress protectors do help reduce exposure, they don’t fully replace the protection of a specialized encasement.
Start by blotting up as much liquid as possible using a clean towel. Avoid rubbing, as that can push the pee deeper into the extra layer of the fabric. Then, spot treat the area with a mix of baking soda, hydrogen peroxide, and a few drops of mild laundry detergent. Let it sit for about 10–15 minutes, then rinse gently with cold water or lukewarm water.
After that, place the protector in the washing machine on a gentle cycle, following the care label. Use low heat to dry it, preserving the waterproof layer and preventing odors from setting in.
If stains or smells remain, repeat the treatment. Soak the protector in a baking soda solution before washing again.
A mattress protector is a thin, waterproof layer designed to shield your mattress and extend its lifespan. A mattress pad, on the other hand, adds a bit of extra cushioning and comfort on top of the mattress. In short, protectors focus on protection, while pads focus on comfort.
Yes, but be cautious. Tumble drying on high heat can cause shrinkage or ruin waterproof coatings. If your label says “tumble dry low,” it’s safe to use the dryer on a gentle, low-heat setting.
If you’re unsure, air drying is always the safest bet. It might take longer, but it keeps your protector’s structure intact for years.
If your mattress protector is quilted or padded, it’s still washable; just treat it more gently. Use a front-loading washer if possible (top-load agitators can be rough).
Avoid wringing or twisting. The goal is to clean it without disrupting the inner fill and damaging stitching.
For protectors with memory foam inserts, spot-cleaning is usually the best approach since submerging foam in water can lead to mold/mildew buildup.
