Cleaning a weighted blanket depends almost entirely on the filling type and fabric cover. Glass bead blankets are safer to machine wash than plastic pellet versions, but both benefit from a removable duvet cover that absorbs most of the dirt and can be washed separately. Here is the complete guide by filling and construction type.
Weighted Blanket Washing Rules by Type
| Filling | Machine wash? | Max weight | Dry method |
|---|---|---|---|
| Glass beads | Yes (if under 15 lbs) | 15 lbs home machine | Air dry or low tumble |
| Plastic pellets | Risky — spot clean preferred | 10 lbs home machine | Air dry only (never high heat) |
| Steel balls (premium) | Spot clean only | Never machine | Air dry only |
| Organic cotton (sewn-in) | Machine (if under 15 lbs) | 15 lbs | Tumble low |
| Removable cover blanket | Wash cover only | n/a (cover handles dirt) | Tumble dry cover |
Method 1: Machine Wash (If Allowed)
- Confirm your home washer is rated for at least 18 lbs (most top-loaders). If your blanket is heavier, use a commercial laundromat washer.
- Use mild, unscented detergent. Quarter the normal amount.
- Cold water, gentle cycle. Hot water damages glass beads and synthetic covers.
- No bleach, no fabric softener.
- Extra rinse cycle to remove soap completely.
- Dry on low heat or air dry only. High heat damages glass beads (they become brittle).
Method 2: Hand Wash (Best for Uncertain Blankets)
- Fill bathtub or large basin with cold water.
- Add 1-2 tablespoons mild detergent.
- Submerge blanket, gently agitate 10-15 minutes.
- Drain, refill with clean cold water, rinse. Repeat 2-3 times.
- Roll in dry towels to absorb water (blanket is heavy when wet).
- Air dry flat on drying rack. Takes 24-48 hours.
Method 3: Cover-Only Wash (Easiest)
If you buy a weighted blanket with a removable duvet-style cover, you only need to wash the cover regularly (weekly is reasonable). The weighted core stays inside protected from most dirt and body oils. The core needs a deep clean maybe once or twice a year.

Stain Removal (Spot Cleaning)
- Food stains: Mix dish soap + cold water. Dab gently. Rinse with cold water.
- Oil / grease: Baking soda powder, let sit 15 min, brush off. Then dish soap and water.
- Blood: Cold water only (hot sets the stain). Hydrogen peroxide if color-safe fabric.
- Pet accidents: Enzyme cleaner (pet-specific). Rinse thoroughly to remove all cleaner.
What NOT to Do
- Do not dry clean. The solvents damage filling materials.
- Do not use bleach — damages glass beads and cotton fibers.
- Do not use fabric softener — reduces cover breathability.
- Do not iron weighted blankets. Heat damages beads.
- Do not wash more often than monthly (unless stained). Over-washing shortens blanket lifespan.
FAQ
How often should I wash my weighted blanket?
Monthly to every 2 months is typical. If you use a removable cover, wash the cover weekly and the core quarterly.
Can I put a weighted blanket in the dryer?
Only on low heat and only if the label allows it. Glass beads can crack under high heat. Plastic pellets melt. Air dry is safer for all types.
Can I wash a 20 lb weighted blanket in a regular washer?
Not recommended. Most home washers are rated for 15-18 lbs max. Use a commercial washer or hand wash.
How do you get pee out of a weighted blanket?
Cold water rinse first, then enzyme cleaner. Air dry. Do not use hot water (sets the stain).
