9 Things You Should Never Put In Your Washing Machine

It’s easy to think the washing machine can handle anything that fits inside. But some things just don’t belong there, no matter how tough they look, or how dirty they are. From delicate fabrics to everyday items that seem harmless, a quick cycle can turn into permanent damage. Here’s what professional cleaners and repair techs say you should always keep out of your washer if you want it to last (and your stuff to survive).

Shoes With Leather Or Suede

Sneakers? Usually fine. Leather boots or suede loafers? Definitely not. The water and agitation can warp the shape and ruin the texture beyond repair. The glue that holds soles together can also loosen in hot water. Instead, wipe them down with a damp cloth or use a specialty cleaner. A little hand care keeps them looking good for years, and saves you from the heartbreak of floppy, misshapen shoes.

Anything Covered In Pet Hair

Before tossing your favorite blanket or sweater in the wash, give it a good shake or run a lint roller over it first. Pet hair clumps up in the water and sticks to everything, including your washer’s drum and drain pump. Over time, that buildup can cause odors and even clogs. A quick brush-off or trip through the dryer on “air fluff” first makes a big difference.

Memory Foam Or Gel Pillows

They might look soft, but inside, these pillows are delicate. The motion and water pressure from the washer can cause them to crumble or tear. Instead, spot clean with mild soap and let them air dry. If they need a refresh, sprinkle a bit of baking soda, let it sit, then vacuum it off. You’ll keep your pillow’s shape and skip the soggy, lumpy mess that a wash cycle creates.

Metal Keys And Coins

It happens to everyone: you forget to check your pockets and a few coins or keys get washed with your pants. But a single coin or key can do real damage inside your machine. They can dent the drum, scratch glass doors, or even get wedged in the filter. Always give your pockets a quick check before pressing start. It’s one of those tiny habits that saves you from big repair bills later.

Bedazzled Or Beaded Clothing

All those sequins and beads might look like they’re attached firmly, but they’re usually hand-stitched or glued on. A single spin cycle can loosen them or tear the fabric of the garments. If you must wash them, turn garments inside out and use a mesh laundry bag on the delicate cycle. But the best option? Hand wash. It takes a little more time but keeps your favorite pieces safe and wearable.

Items Labeled “Dry Clean Only”

There’s a reason that tag exists. Water and detergent can ruin the fabric’s finish or cause shrinkage that no amount of ironing will fix. Even gentle cycles can warp delicate fibers like silk or wool and ruin your clothes. Instead, spot clean small stains or use at-home dry-cleaning kits. For anything valuable, take it to a professional cleaner. It might cost a bit more, but it’s better than replacing an entire outfit.

Heavy Or Oversized Rugs

Washing a rug in the machine might seem like a great shortcut, but those heavy fibers can throw your machine off balance and strain the motor. If the rug holds too much water, it can even cause leaks. For small, washable mats, they should have no problem in the machine. But anything large or thick belongs outside for a good hose-down or at a laundromat with industrial-sized washers. Your machine, and your floors, will thank you.

Not all plush toys are machine-safe, especially those with glued-on eyes, sound boxes, or delicate stitching. The washer’s motion can pop seams and damage fillings too. If your child’s favorite stuffed friend needs a wash, use a pillowcase as a protective bag and wash it on the gentlest cycle possible. Or better yet, spot clean with a mild soap solution. A little patience goes a long way with sentimental things.

Too Much Laundry At Once

It’s not exactly an “item,” but overloading your washer might be the worst mistake of all. When it’s too full, clothes can’t move freely, meaning detergent can’t do its job. It also strains the motor and bearings of your machine. Two smaller loads clean better and dry faster than one stuffed one. Think of it as giving your washer (and your clothes) a little room to breathe.
