Expert consulted: 
There are plenty of things you probably don't think twice about putting in the washer. But cleaning experts want you to avoid putting certain items in the washing machine because they can damage the appliance or the items themselves.
Modern washing machines are relatively sturdy, but seemingly small things like an excess of pet hair or loose coins can put undue stress on your washer or even cause it to malfunction. On the other side of the equation, certain items, like foam pillows and vintage items, are too delicate to stand up to the powerful agitation and spinning of the washer.
If you're not sure whether an item can go through the washer, look for a care tag or any instructions that came with the item to find info on the best way to clean it. When in doubt, it's often safer to spot-treat or hand-wash an item than to put it in the machine.

If you're looking for even more tips on avoiding laundry mishaps, read up on the laundry mistakes pros say can ruin your clothes and the laundry items you're probably washing on the wrong setting.
Extremely dirty items
Things like sandy towels, blankets covered in pet hair and muddy clothes shouldn't be thrown directly into the washing machine. Not only can a large amount of sand, dirt or pet hair damage a washer, but your clothing won't get clean. Shake out very dirty towels, clothing and linens outside or over the trash can before machine washing them. You can also use a lint roller to remove a majority of dog hair.
Solid foam pillows
Solid memory foam pillows provide great neck support, but they should never be machine washed. The machine's agitation and high-speed spin can damage the foam. "They probably shouldn't even be hand-washed, as the foam can tear from the weight of the water," says Forté. Instead, invest in a machine-washable pillow cover!
Weighted or very heavy blankets
Some large and weighted blankets may claim to be machine washable, but it's important to consider the size and capacity of your washer. While extra-large home washers can often handle mixed loads of 22 to 24 pounds, a single 20-pound item can put a strain on your machine. Our experts recommend not washing a weighted blanket of more than 15 pounds, even if your washer can typically handle 20-pound loads.

Items labeled dry clean only
Always check the care label before machine washing clothes. If the label reads "dry clean only," you run the risk of damaging, shrinking or fading your clothes. Delicate fabrics (think silk, cashmere and leather), embellished items and formal attire, like suits and gowns, tend to be dry clean only. Certain blankets and pillows shouldn't be machine washed either.

Vintage and delicate clothing
Vintage garments or modern clothing made from delicate fabrics (again: silk, cashmere, suede and lace) should not be machine washed. Instead, these items should be hand-washed with mild detergent in cold water or brought to a dry cleaner. We recommend dry cleaning for pleated skirts, leather clothing and any garments with embellishments like jewels, sequins, leather patches or detailed trims.
Items with an unzipped zipper
Whether you're washing denim jeans, jackets or bedding, always make sure zippers are fully closed. The teeth of an open zipper can easily get stuck on fabrics and tear your clothing. Also, be sure to zip up mesh laundry bags before tossing them in the washer.
Anything left behind in pockets
As you're loading the washer, always check pockets for stray items — like coins, keys, tissues, old receipts or lip balm. Not only can things like lip balms, paper receipts and tissues get all over clothing, but metal items (think coins and keys) can damage a washer.
Leather clothing
As mentioned earlier, certain fabrics — like leather — should steer clear of the washing machine. When exposed to a wash cycle or high heat, leather can crack, wrinkle or shrink. Hand-wash leather jackets, pants or accessories, or simply spot-clean them as needed.
Dark and bright-colored clothing that might bleed
Certain dyes, especially reds and oranges, are known to bleed color in the wash — especially when the item is brand new. This can cause an entire load to stain. If you're worried about color bleeding, it's best to hand-wash the item separately.
