Keeping your mattress cover clean is essential for a healthy sleep environment. This guide will show you how to wash mattress cover properly to extend its life and keep your bed fresh. It might seem like a big task, but with the right steps, it’s simple and effective.
First, don’t just throw it in the washer. The method depends entirely on the type of cover you have. Checking the care label is the single most important step you can take. Ignoring it could lead to shrinkage, damage, or a ruined waterproof layer.
How to Wash Mattress Cover
The core process involves preparation, washing, and drying. We’ll break down each stage for different materials, including waterproof and mattress encasements.
Step 1: Identify Your Mattress Cover Type
Not all mattress covers are washed the same way. Here’s how to tell what you have:
* Fitted Mattress Pad/Topper: Usually quilted with a soft filling (like cotton or polyester). It sits on top of your mattress and has elastic corners.
* Waterproof Mattress Protector: Often has a thin, vinyl, PVC, or polyurethane layer. It might feel slightly plastic-y and is designed to block liquids.
* Mattress Encasement: Zips completely around your mattress like a giant pillowcase. It offers full protection from allergens and bed bugs.
* Cooling or Specialty Covers: Made from fabrics like bamboo, Tencel, or wool. They have specific care needs.
Step 2: Check the Care Label (Non-Negotiable!)
Look for the tag, usually sewn along a seam. It will tell you:
* Maximum washing temperature.
* Whether to use a gentle cycle.
* Drying instructions (tumble dry low, air dry, etc.).
* Any warnings (like no bleach or no ironing).
If the tag is missing, use the guidelines below based on the material.
Pre-Wash Preparation
A little prep prevents a mess in your washing machine.
1. Strip the Bed: Remove all sheets, pillowcases, and other bedding.
2. Spot Clean Stains: Treat any visible stains (like blood, sweat, or urine) before washing. Use a mild enzyme cleaner or a paste of baking soda and water. Gently dab, don’t rub.
3. Fasten All Closures: Zip up encasements completely. Secure any hook-and-loop tabs or buttons. This prevents snagging and tearing.
4. Shake it Out: Take the cover outside and give it a good shake to remove loose dust, hair, and debris.
Step 3: Washing Instructions by Material
Now, let’s get into the machine settings.
For Cotton, Polyester, or Bamboo Covers (Most Common)
These are generally the easiest to care for.
* Machine Wash: Use cold or warm water on a gentle or delicate cycle. Hot water can cause shrinkage.
* Detergent: Use a mild, liquid detergent. Avoid powdered detergents as they sometimes don’t fully dissolve on gentle cycles. Skip fabric softener—it can coat fibers and reduce breathability.
* Extra Rinse: If you have allergies, consider an extra rinse cycle to remove all detergent residue.
For Waterproof Mattress Protectors
The waterproof layer needs gentle handling to maintain its integrity.
* Machine Wash Alone: Wash it by itself to avoid snagging or abrasion from zippers or buttons on other items.
* Cold Water & Gentle Cycle: Always use cold water. A gentle cycle is crucial to protect the waterproof membrane.
* Mild Detergent Only: Use a small amount of mild detergent. Never use bleach, vinegar, or fabric softener. These chemicals can break down the waterproof coating, making it brittle and causing it to crack or peel. This is a common mistake that ruins protectors.
For Mattress Encasements
Follow the care label closely. If missing, treat it as a waterproof protector.
* Zip It Fully: Ensure the zipper is completely closed.
* Gentle Cycle & Cold Water: This protects the zipper and any waterproof layers.
* Check for Damage: Before washing, inspect the zipper and seams for any tears. Washing can make small holes much bigger.
For Wool or Delicate Fiber Covers
Wool is naturally resistant to stains and odors, but it requires special care.
* Hand Wash Recommended: The safest method is to hand wash in cold water with a wool-specific detergent.
* If Machine Washing: Use a wool or handwash cycle with cold water. Never use warm or hot water, as it will felt and shrink the wool.
* Lay Flat to Dry: Always air dry wool flat; never put it in the dryer.
Step 4: Drying Your Mattress Cover Thoroughly
Proper drying is just as important as washing. A damp cover can lead to mildew inside your mattress.
* Tumble Dry Low: For most cotton, polyester, and bamboo covers, a low heat setting is safe. Remove promptly to prevent wrinkles.
* Air Drying is Best for Waterproof Items: The absolute safest way to dry a waterproof protector or encasement is to hang it over a shower rod or clothesline. This prevents any heat damage to the plastic layer. If you must use a dryer, use NO HEAT or AIR FLUFF only.
* Check for Dampness: Before putting it back on your bed, feel all layers and seams to ensure it’s 100% dry, especially the corners.
Step 5: Putting the Clean Cover Back On
Once completely dry, put it back on your mattress carefully.
1. Align the cover with the corners of your mattress.
2. For fitted covers, stretch the elastic over each corner smoothly. Don’t just pull one side—work your way around to avoid straining the seams.
3. For encasements, zip it up slowly, ensuring the mattress is fully inside and the zipper doesn’t catch the fabric.
How Often Should You Wash Your Mattress Cover?
A good rule of thumb is to wash it every 1-2 months. However, you should wash it immediately if:
* There is a spill or accident.
* You’ve been sick with a fever or night sweats.
* Allergy symptoms seem worse.
* You notice any odors.
It’s a good idea to align washing your mattress cover with washing your pillows for a full bed refresh.
Common Washing Problems and Solutions
What if my cover shrank?
Unfortunately, shrinkage is often permanent if caused by high heat. You can try to gently stretch it while it’s still damp and air dry it. Prevention is key: always wash in cool water and dry on low or no heat.
The waterproof layer feels sticky or cracked.
This usually means the coating has degraded from harsh detergents, softeners, or high heat. The cover likely needs to be replaced. For a new one, always follow the gentle care instructions.
There’s a lingering odor after washing.
This can happen if it wasn’t dried quickly enough or detergent got trapped. Rewash it without detergent on a gentle cycle, then dry immediately. Adding a half-cup of baking soda to the wash can help neutralize odors.
My cover has bulky filling that won’t dry.
For thick, quilted toppers, use a dryer on low heat and add a couple of clean, dry towels or dryer balls. They will help absorb moisture and agitate the filling for even drying. Be prepared for it to take a few cycles.
FAQ Section
Can you put a mattress cover in the washing machine?
Yes, most modern mattress covers are machine washable. Always check the care label first. Use a gentle cycle with cold or warm water and mild detergent. Very old or delicate covers might need hand washing.
What is the best way to clean a mattress protector?
The best way is to follow the manufacturer’s label. Generally, wash it alone on a cold, gentle cycle with mild detergent. Avoid bleach and fabric softener. Air drying is the safest method to preserve the waterproof layer.
How do you wash a bed cover that is waterproof?
Wash it by itself in cold water on a delicate cycle. Use a small amount of mild liquid detergent. Do not use vinegar, bleach, or softener. Tumble dry on no heat or, ideally, hang it to air dry completely.
Can you wash a mattress pad in hot water?
It’s not usually recommended. Hot water can cause shrinkage, set protein-based stains (like sweat), and damage waterproof coatings. Warm or cold water is safer for most materials and is effective with modern detergents.
How do you dry a mattress cover quickly?
The fastest safe method is using a dryer on a low heat or air fluff setting. Adding dry towels can speed up moisture absorption. For non-waterproof covers, you can partially air dry and then finish in the dryer on low to soften it up.
Keeping your mattress cover clean doesn’t have to be a chore. By knowing your material, pre-treating stains, and using gentle cycles with cool water, you can maintain a fresh and hygienic sleep surface for years to come. Regular cleaning protects your investment in your mattress itself, ensuring you get the best sleep possible. Remember, when in doubt, that care label is your best friend.
