How Often Should You Wash Pillow Covers? The Complete Pillowcase Cleaning Guide
Your pillow cover may look clean, but every night it comes into direct contact with your face, hair, skin, sweat and natural body oils. Over time, these can build up along with dust, dead skin cells, skincare or makeup residue and other everyday debris.
So, how often should you wash pillow covers?
For most people, the best rule is once a week, ideally at the same time you wash your bedsheets. Sleep Foundation also recommends washing pillowcases at least weekly, while people who sweat heavily, have pets sleeping on the bed, or experience allergies may benefit from washing them more frequently.
If you want a cleaner, fresher and more comfortable bedroom, establishing a regular pillow cover washing routine is one of the easiest habits to adopt.
How Often Should You Wash Pillow Covers?
For everyday use, wash your pillow covers once every 7 days.
However, your ideal washing frequency can change depending on your lifestyle:
| Situation | Recommended Pillow Cover Washing |
|---|---|
|
Normal everyday use |
Once a week |
|
Heavy sweating at night |
2–3 times a week |
|
Oily skin or hair |
2–3 times a week |
|
Pets sleep on your bed |
2–3 times a week |
|
Allergies or sensitivity to dust |
Several times a week to weekly |
|
After illness |
Wash immediately |
|
Pillow cover visibly dirty/stained |
Wash immediately |
|
Hot and humid weather |
More frequently, as needed |
Pillowcases are among the bedding items that have the most direct contact with your body, so they generally require more frequent washing than items such as blankets or comforters.
Why Is It Important to Wash Pillow Covers Regularly?
Your pillow cover acts as a protective layer between your face and pillow. But that doesn’t mean it stays clean indefinitely.
During sleep, your pillow cover can collect:
- Sweat
- Facial oils
- Hair oils
- Dead skin cells
- Dust
- Skincare products
- Makeup residue
- Saliva
- Pet hair and dander
- Everyday dirt
Over time, this buildup can make your bedding feel less fresh and may contribute to unpleasant odours and irritation for some people.
Regular washing helps maintain better sleep hygiene and keeps your bedroom bedding fresh.
Sleep Foundation notes that bedding can accumulate sweat, oils, dirt and allergens, and recommends washing pillowcases and sheets regularly.
Can Dirty Pillow Covers Cause Skin Problems?
A pillow cover comes into contact with your face for several hours every night. If you go to bed with skincare products, makeup, hair products or excess facial oil, some of that residue can transfer onto the fabric.
A pillowcase that isn’t washed regularly can therefore accumulate oils and other residues.
If you are prone to oily skin, acne or skin irritation, changing your pillow cover more frequently may be a useful part of your overall hygiene routine.
However, pillowcase cleanliness isn’t the only factor affecting skin health. If you experience persistent acne or irritation, consider speaking with a qualified dermatologist.
How Often Should You Wash Pillow Covers in Summer?
In hot and humid weather, you may need to wash your pillow covers more frequently than once a week.
This is especially true if you:
- Sweat heavily while sleeping
- Sleep without air conditioning
- Live in a hot or humid environment
- Have oily skin or hair
- Exercise frequently
- Use heavy hair oils or styling products
Summer sweat can make pillow covers feel dirty faster. A practical approach is to keep multiple pillow cover sets so you can replace them quickly while the used ones are being washed.
How Often Should You Wash Pillow Covers If You Have Pets?
If your dog or cat sleeps on your bed, consider increasing your pillow cover washing frequency.
Pets can bring hair, dander and outdoor dirt onto bedding. Sleep Foundation recommends washing bedding more frequently when pets sleep in the bed.
In this situation, changing pillow covers two or more times per week can be a practical choice depending on how much exposure there is.
You should also regularly wash your bedsheets and clean the surrounding bedroom area.
How Often Should You Wash Pillow Covers If You Have Allergies?
People who are sensitive to dust or allergens may benefit from more frequent bedding changes.
Dust mites and other allergens can accumulate in bedding, and regular cleaning can help reduce this buildup. Sleep Foundation recommends more frequent bedding cleaning for people with allergies or asthma.
For allergy-sensitive households, focus on a complete bedding routine rather than washing only the pillow covers:
Pillow covers → Bedsheets → Mattress protector → Pillow → Blankets
Always follow the manufacturer’s care instructions for each item.
How to Wash Pillow Covers Properly
Simply putting your pillow covers into the washing machine isn’t always enough. Proper washing can help maintain their appearance, softness and durability.
1. Check the Care Label
Before washing, check the manufacturer’s instructions.
Different fabrics may have different requirements for:
- Water temperature
- Detergent
- Washing cycle
- Drying
- Ironing
- Bleaching
When in doubt, follow the care label rather than using a generic washing method.
2. Separate Colours
Wash white, light-coloured and dark pillow covers separately when possible.
This can help reduce the risk of colour transfer.
3. Don’t Overload the Washing Machine
Give your pillow covers enough room to move around during the wash cycle.
Overloading the machine can reduce washing effectiveness and may leave some areas inadequately cleaned.
4. Use a Suitable Detergent
A mild or suitable laundry detergent is generally a good option for regular bedding.
If you have sensitive skin, choose a detergent appropriate for sensitive skin and follow the manufacturer’s instructions.
5. Dry Completely
Make sure pillow covers are completely dry before putting them back on your pillows.
Damp bedding should not be stored or used because prolonged moisture can create an unsuitable environment for mould and unpleasant odours.
How Often Should You Change Pillow Covers?
Washing and replacing are two different things.
You should wash pillow covers weekly, but you don’t necessarily need to replace them every week.
Sleep Foundation recommends replacing pillowcases approximately every 1–2 years, depending on their condition and material.
Consider replacing a pillow cover sooner if you notice:
- Permanent stains
- Faded or damaged fabric
- Fraying seams
- Holes or tears
- Elastic or fastening damage
- Persistent odour
- Fabric becoming excessively thin
Investing in several quality pillow covers can make it easier to maintain a consistent bedding hygiene routine.
How Many Pillow Covers Should You Own?
For a practical bedroom linen collection, having 3–4 sets of pillow covers per pillow is a convenient option.
For example:
1 set in use + 1 set in the laundry + 1–2 clean spare sets
This means you don’t have to wait for laundry day before changing your pillow covers.
If you regularly wash your entire bedding set, coordinating your pillow covers and bedsheets can make bedroom maintenance much easier.
For example, Jazkaa Luxe’s King Size Cotton Bedsheet Set includes two matching pillow covers and is made from breathable cotton designed for everyday use.

Pillow Cover vs Pillow Protector: What's the Difference?
Many people use the terms interchangeably, but pillow covers and pillow protectors serve different purposes.
Pillow Cover
A pillow cover or pillowcase is the outer bedding layer that you sleep directly on.
It should be washed frequently—generally once a week or more often when needed.
Pillow Protector
A pillow protector is an additional layer placed between the pillow and pillowcase.
It provides an extra barrier against sweat, oils, dust and other everyday buildup.
Some pillow protectors are designed to be removable and washable, making them particularly useful for maintaining pillow hygiene.
Sleep.com notes that washable pillow protectors can help protect the pillow and may allow the pillow itself to be cleaned less frequently, depending on its material and care instructions.
How Often Should You Wash Your Pillow?
Don’t confuse washing your pillow cover with washing the actual pillow.
Pillow covers should generally be washed weekly, while washable pillow inserts themselves usually require much less frequent cleaning.
Sleep Foundation suggests washing many washable pillows approximately every 4–6 months, although the appropriate schedule depends heavily on the pillow material and manufacturer instructions.
Some pillows—particularly memory foam and certain latex pillows—should not be placed in a washing machine. They may require spot cleaning or other care methods.
Always check your pillow’s care label before washing it.
What About Your Bedsheets?
If you’re wondering how often to wash pillow covers, it’s useful to create a complete bedding cleaning schedule.
A simple routine could look like this:
- Pillow covers: Once a week
- Bedsheets: Once a week
- Pillow protectors: About monthly, depending on use and care instructions
- Pillows: Approximately every 4–6 months if washable
- Duvet covers: Every 2 weeks to monthly
- Comforters/blankets: Every 2–3 months, depending on use
These are general guidelines rather than strict rules. Your lifestyle, climate, pets, allergies and fabric type can all affect the ideal schedule.
7 Signs Your Pillow Cover Needs Washing
Not sure whether it’s time for laundry day?
Look for these signs:
1. It Smells Different
A noticeable sweat or musty smell is a clear indication that it’s time for a wash.
2. You Can See Stains
Yellowish or darker marks can develop from sweat, oils and other residue.
3. The Fabric Feels Oily
An oily or slightly sticky texture can indicate buildup from skin and hair oils.
4. You’ve Been Sweating More
Hot weather or increased physical activity can make bedding dirty faster.
5. You’ve Been Sick
Change and wash your pillow covers after illness to refresh your bedding.
6. Your Pet Sleeps on the Bed
Pet hair and dander can accumulate quickly.
7. It’s Been More Than a Week
Even when your pillow cover looks clean, weekly washing is a useful baseline for regular sleepers.
How to Keep Pillow Covers Fresh Between Washes
Want your bedding to stay fresher for longer?
Try these simple habits:
✔ Shower before bed
A clean body means less sweat, dirt and product transfer onto your bedding.
✔ Avoid sleeping with makeup on
Makeup can transfer onto your pillowcase.
✔ Don’t go to bed with wet hair
Excess moisture can transfer into bedding.
✔ Air your bedroom regularly
Good ventilation helps reduce stuffiness and moisture.
✔ Keep pets off pillows
If pets sleep on your bed, try keeping them away from your pillow.
✔ Keep spare pillow covers available
This makes changing them regularly much easier.
✔ Wash your bedsheets and pillow covers together
This creates a simple weekly bedding routine.
Choosing the Right Pillow Covers for Everyday Use
When buying pillow covers, don’t focus only on appearance.
Consider:
Fabric
Cotton is a popular choice for everyday bedding because it can feel soft and breathable. Jazkaa Luxe’s cotton bedsheet collection, for example, focuses on soft, breathable fabric suitable for regular use.
Size
Make sure the pillow cover fits your pillow properly. An oversized or undersized cover can affect both appearance and comfort.
Breathability
For warm climates, breathable bedding can help create a more comfortable sleeping environment.
Durability
Since pillow covers are washed frequently, look for fabrics and stitching that can handle regular laundering.
Design
Your pillow covers don’t have to be purely functional. Coordinated bedding can instantly improve the overall appearance of your bedroom.
