9 Not-Obvious Things You Should Never Put in the Washing Machine

Don't forget to double-check those pockets!

The modern electric washing machine is one of the greatest inventions of the 20th century. Back in the day, one would have to spend hours boiling water, hand-scrubbing clothing, hanging it out to dry, ironing, folding, and finally putting it all away, only to start all over again. The modern appliance transformed women's lives, letting them get out of the laundry room and into the workforce or anywhere else they preferred to be. It's a miracle product. That said, it can't clean everything, and the machine can't read the tag on an item to see if it's safe to stick in the wash or choose the right settings without some help from us.

Open Washing Machine with Dress Shirts Inside

Here are a few things you should never put in the washing machine:

Delicate Embellishments

Those beautifully delicate items covered in sequins, beading, or fragile embroidery can be destroyed in the washing machine, especially if they are glued on instead of sewn. Similarly, take care washing anything made with lace, which can rip or tear in a washer, especially if it rubs against clothing that has hooks, buttons, or zippers. Hand-wash or dry clean those items instead.


The underwire and hook-and-eye closures can damage the interior of your washing machine, turning a $30 bra into a $600 mistake. Lace can also get damaged. Instead, either hand-wash your lingerie or invest in a protective mesh bag to keep your bras, garments, and machine safe. Don't have a mesh bag? A pillowcase will do the trick.

Coins and Keys

While most of us wouldn't intentionally wash our keys or change in the machine, almost everyone has accidentally left a few coins or a spare key in the pocket of a pair of jeans at some point. If the keys or coins stay put, it can be a harmless mistake, but if they get loose, they can do a lot of damage. "[Coins] can damage the fins on the drain pump if they make it past the filter," James Peters, Kenmore Director of Product Management, told Business Insider. They could also get stuck in the washing machine's drain (in turn blocking the water), damage the drum, or even shatter the glass of a front-loading washer. Luckily, the solution is easy: Simply check pockets while you load the machine.

Running Shoes with Leather

While you can wash some sneakers in your machine, be aware that it can shrink the shoes or reduce some qualities that make them able to take a beating on the road. Also, remember that shoes with leather accents should never go in the machine as it can damage the leather. While it's safest to hand-wash your expensive running gear and let them air dry, if the tag says they're machine-safe, Livestrong suggests removing the insoles and putting each shoe in a separate pillowcase and then air drying.

Flammable Stains

If you spill gas, paint thinner, or another combustible solvent on your clothing, do not stick it in the dryer. The heat could cause the stain to combust and cause a fire. Instead, according to Carolyn Forte, executive director of the Home Appliances & Cleaning Products Lab at the Good Housekeeping Institute, who spoke to Prevention, spot-treat the stain with a solvent-based stain remover (like Spray n' Wash), let it sit for at least ten minutes, machine wash alone so it doesn't transfer the toxic stain, and hang dry. Alternatively, The Spruce recommends rubbing a paste of two parts baking soda with one part water into the stain, and then washing and hanging to dry. Otherwise, hand-wash the item in hot water with liquid detergent and then hang to dry.

Baby Socks

As every parent knows, baby socks disappear with an alarming frequency. According to HGTV, though, one culprit may be the washing machine. Baby socks are so tiny that they can be sucked into the hoses and vents on your washer and dryer. Not only does this mean having to purchase a steady supply of ridiculously small socks, but they can clog the machine leading to flooding and costly repairs. It's worth buying a mesh laundry bag to safely corral the little things.

Pet Hair–Covered Clothing

While we all love cuddling with our beloved pups and favorite lap kittens, the hair they frequently leave behind is less than adorable. Your first instinct may be to immediately chuck the hair-covered pants in the washer, but it's worth taking a moment to remove the hair first with a lint roller or brush. Randy Radtke, spokesperson for laundry appliance maker Speed Queen, a company that makes both commercial and residential washers, told Consumer Reports that if you chuck it straight in the washer, the hair gets wet, clumps, and can stick to the sides of the washing machine, spreading the hair to your next load of laundry. Plus, all that hair can run down your drain, clogging pipes. Another option for removing pet hair from clothing is to stick it in the dryer first where the steady motion, heat, dryer sheet, and lint trap can remove and capture the hair.

Too Much Laundry

Your washer and dryer can do a lot, but overstuffing tends to cause bigger problems than forcing you to do a second load of laundry. Overloading the machine means the washer can't clean your clothes properly, and the dryer won't be able to generate air flow to dry clothes evenly. Plus, overloading can lead to breakdowns. Not only do heavy loads strain the drum belt and bearings, but they can also cause the motor to overheat and burn out. Check the manufacturer's suggestions for your particular model's capacity and consider taking big items like comforters to the dry cleaner or laundromat.


Suits tend to be high-priced, special-occasion clothing made of high-quality fabric. Protect your investment by always dry cleaning your suits, as even the delicate cycle can be too much for the clothing. Instead, bring them to the dry cleaner. In between dry cleaner drop-offs, use a steamer to de-wrinkle your suit.
