Washing your bedding correctly can mean the difference between sheets that last 5 years and sheets that pill and fade after a few months. Yet most people wash their bedding the same way they wash everything else — hot water, regular detergent, high heat dryer. This guide covers the right way to wash every type of bedding material.
How often should you wash your bedding?
| Item | Frequency | Why |
|---|---|---|
| Sheets and pillowcases | Every 1-2 weeks | Sweat, oils, dead skin cells accumulate |
| Duvet cover | Every 2-4 weeks | Less direct skin contact |
| Comforter/duvet insert | Every 2-3 months | Protected by cover |
| Pillows | Every 3-6 months | Absorb moisture and oils over time |
| Mattress protector | Monthly | Barrier against sweat and allergens |
General bedding washing rules
These rules apply to almost all bedding materials:
- Read the care label first — always check manufacturer instructions
- Wash bedding separately — do not mix with clothes, towels, or items with zippers
- Use cold or warm water — hot water breaks down fibers faster and can cause shrinkage
- Choose gentle detergent — avoid bleach, fabric softener, and harsh chemicals
- Do not overload — sheets need room to move for proper cleaning
- Tumble dry on low — high heat damages fibers and causes shrinkage
How to wash Tencel bedding
Tencel (lyocell) is durable but requires slightly more care than cotton. The good news: Tencel actually gets softer with each wash.
- Water temperature: Cold (30C / 86F) or cool
- Cycle: Gentle or delicate
- Detergent: Mild liquid detergent (no powder)
- Avoid: Bleach, fabric softener, dryer sheets
- Drying: Tumble dry on low heat, or air dry (best option)
- Ironing: Low heat if needed, but Tencel naturally resists wrinkles
Pro tip: Turn your Tencel duvet cover inside out before washing. This protects the outer surface from friction and helps maintain the silky feel.

How to wash cotton bedding
Cotton is the most forgiving bedding material to wash, but proper care still extends its life significantly.
- Water temperature: Warm (40C / 104F) for regular washes; hot for sanitizing (occasional)
- Cycle: Normal or gentle
- Detergent: Regular or gentle detergent
- Bleach: Only oxygen-based bleach for whites (never chlorine)
- Drying: Tumble dry on medium heat
- Ironing: Medium-high heat; cotton wrinkles easily
Pro tip: Add white vinegar (1/2 cup) to the rinse cycle every few washes. It naturally softens cotton, removes detergent buildup, and brightens whites without chemicals.
How to wash silk and satin bedding
Silk requires the most careful handling of any bedding material.
- Water temperature: Cold only (30C / 86F)
- Cycle: Delicate or hand wash
- Detergent: Silk-specific or very mild pH-neutral detergent
- Avoid: All bleach, fabric softener, wringing, twisting
- Drying: Air dry flat, away from direct sunlight
- Ironing: Low heat on reverse side only, or use a pressing cloth
How to wash microfiber bedding
Microfiber (polyester) is the easiest bedding material to care for.
- Water temperature: Cold or warm
- Cycle: Normal
- Detergent: Regular detergent (avoid fabric softener — it coats the fibers)
- Drying: Tumble dry on low heat or air dry
- Ironing: Usually unnecessary — microfiber resists wrinkles
How to wash bamboo bedding
- Water temperature: Cold (30C / 86F)
- Cycle: Gentle
- Detergent: Mild liquid detergent
- Avoid: Bleach, fabric softener
- Drying: Tumble dry on low or air dry
Bamboo viscose has similar care requirements to Tencel since both are regenerated cellulose fibers.
Common bedding washing mistakes
1. Using too much detergent
More detergent does not mean cleaner sheets. Excess detergent leaves residue that makes sheets feel stiff, causes skin irritation, and attracts more dirt. Use the recommended amount — or slightly less.
2. Washing in hot water every time
Hot water breaks down fibers, causes color fading, and can shrink natural fiber sheets. Save hot water for occasional sanitizing washes only (e.g., after illness).
3. Using fabric softener
Fabric softener coats fibers with a waxy layer that reduces breathability, moisture-wicking, and natural softness. This is especially harmful for Tencel and bamboo sheets, which are naturally soft. Use white vinegar instead.
4. Overloading the washer
Sheets need room to agitate and rinse properly. Wash one set at a time — do not stuff multiple sets into one load.
5. Using high heat in the dryer
High heat weakens fibers, causes shrinkage, and can create permanent wrinkles. Always use low or medium heat.
How to remove common bedding stains
| Stain | Treatment |
|---|---|
| Blood | Cold water + hydrogen peroxide (dab, do not rub) |
| Sweat/yellowing | Baking soda paste + white vinegar soak |
| Coffee/tea | Cold water rinse + mild dish soap |
| Oil/grease | Dish soap directly on stain, wait 10 min, cold wash |
| Makeup | Rubbing alcohol on a cotton ball, dab gently |
Golden rule: Always treat stains with cold water first. Hot water sets protein-based stains (blood, sweat) permanently.
How to store bedding properly
- Store in a cool, dry place (linen closet or shelf)
- Use breathable cotton storage bags — never plastic bags (traps moisture, causes yellowing)
- Add a lavender sachet for a fresh scent and to repel moths
- Fold neatly to prevent permanent creases
- Rotate your bedding sets — using 2-3 sets in rotation extends each set lifespan by 50-100%
Bedding care cheat sheet
| Material | Water Temp | Cycle | Dryer | Special Notes |
|---|---|---|---|---|
| Tencel | Cold | Gentle | Low | Gets softer with washing |
| Cotton | Warm | Normal | Medium | Vinegar rinse helps |
| Silk | Cold | Delicate | Air dry | Hand wash if possible |
| Microfiber | Cold/Warm | Normal | Low | No fabric softener |
| Bamboo | Cold | Gentle | Low | Similar to Tencel care |
Frequently asked questions
Can you wash bedding in cold water?
Yes, and you should for most materials. Cold water is gentler on fibers, prevents shrinkage, saves energy, and is sufficient for regular cleaning. Use warm or hot water only for occasional deep sanitizing.
Should you wash new sheets before using them?
Absolutely. New sheets may contain manufacturing residues, excess dye, and sizing chemicals. Wash new sheets once before first use. This also helps soften cotton sheets.
How many sets of sheets should you own?
Ideally 2-3 sets per bed. This allows you to rotate while one set is in the wash, and extends the lifespan of each set. See our buying guide: Best Bedding Sets Under $50
Why do my sheets smell after washing?
Usually caused by excess detergent buildup, washing in cold water without enough detergent, or leaving damp sheets in the washer too long. Try: less detergent, warm water wash, and immediate drying after washing.
Can you dry bedding in direct sunlight?
Sunlight naturally sanitizes and whitens sheets, but prolonged sun exposure can fade colors. Best approach: air dry in indirect sunlight or shade for colored sheets; direct sunlight is fine for whites.
