Ever wondered why a heavy blanket can turn a simple laundry day into a risky guessing game? The truth is, washing oversized throws, weighted blankets, and thick comforters the wrong way can damage both the fabric and your washing machine. If you want to learn how to wash heavy blankets in washing machine without ruining them, the key is to check a few things before pressing start.
What to Know Before You Wash a Heavy Blanket
Before you wash a heavy blanket in washing machine, look at the care label first. Some materials, such as wool, fleece, sherpa, and weighted blanket fillings, may need special handling or professional cleaning. The label will tell you whether the blanket is machine washable, which water temperature to use, and whether it should be air dried or tumble dried on low.
Next, check your washer’s capacity. A blanket that looks manageable can still be too large once it gets wet. If the blanket fills the drum more than about two-thirds of the way, it may not clean properly. Overloading can also strain the motor, cause poor rinsing, and lead to imbalance during the spin cycle.
How to Wash Heavy Blankets in Washing Machine Safely
1. Shake and Inspect the Blanket
Start by shaking out dust, pet hair, and debris. Check for loose seams, holes, or stained areas. Spot treating stains before washing gives you a better chance of a full clean without needing a second cycle.
2. Use the Right Washer Settings
When washing bulky blankets in a washing machine, choose a gentle or bulky cycle if your machine has one. Use cold or warm water based on the care label. Cold water is usually the safest choice for preserving fibers and preventing shrinkage.
3. Pick a Mild Detergent
Use a small amount of mild liquid detergent. Too much soap can trap residue inside thick fabric and make rinsing harder. For sensitive materials, avoid bleach and strong stain removers unless the label allows them.
4. Balance the Load
If your washer allows it, wash the blanket alone. If the drum feels off balance, add a few towels to help distribute the weight evenly. This can reduce shaking and improve spin performance, especially in a top load washer.
Can You Wash a Heavy Blanket in a Top Load Washer?
Yes, but only if the blanket fits comfortably and the washer has enough capacity. A top load washer can handle many heavy blankets, but large or dense ones may absorb too much water and become too heavy. If the blanket is tightly packed in the drum, it is better to use a larger machine or a laundromat washer.
How to Dry Heavy Blankets After Washing
Drying is just as important as washing. If the care label allows machine drying, use low heat or no heat. High heat can shrink fabric, damage fillings, and weaken seams. For extra thick blankets, pause the dryer and fluff the blanket occasionally so it dries evenly.
Air drying is often the safest option for large blankets. Lay it flat on a clean surface or drying rack to help it keep its shape. Make sure it is fully dry before putting it away to prevent mildew.
Final Tips for Washing Bulky Blankets
If you are unsure how to wash heavy blankets in washing machine, always start with the label and your washer’s size. Washing a heavy blanket correctly helps protect the fabric, improve cleanliness, and extend the life of both the blanket and the appliance. When in doubt, choose a gentle cycle, use less detergent, and avoid overloading your machine.
