Should You Zip Zippers Before Washing?

Leaving a zipper open in the washing machine can let the teeth and slider rub, catch or snag against nearby fabric. Closing it first is a simple way to protect both the zipped garment and the other clothes in the load.

Direct answer: Yes, in most cases you should close zippers before washing. A closed zipper keeps the teeth together and reduces the chance of the zipper catching on T-shirts, sportswear, prints or delicate fabrics. After zipping, turn the garment inside out when suitable and follow its care label. Do not force a damaged or jammed zipper closed, and do not assume the same rule applies to buttons, which are usually better left unbuttoned to reduce stress on the buttonholes.

Close the Zipper

Bring the slider fully up so exposed teeth are less likely to catch on nearby clothing during the wash.

Turn It Inside Out

For suitable garments, washing inside out can reduce rubbing on the outer fabric, print and zipper surface.

Check the Care Label

Use the temperature and cycle recommended for the garment rather than relying on a general zipper rule alone.

Quick comparison

What Should You Fasten Before Washing?

Fastener or detail	Before washing	Why
Zippers	Close	Reduces exposed teeth and lowers snagging risk
Buttons	Usually unbutton	Helps reduce pulling on buttons and buttonholes
Hooks and clasps	Fasten or use a laundry bag	Prevents small hooks from catching other fabrics
Hook-and-loop fasteners	Close	Keeps the rough hook side from attaching to other garments
Drawstrings	Tie loosely if needed	Helps stop long cords from tangling or pulling out
Damaged zippers	Do not force	A jammed slider or broken teeth can worsen in the wash

Simple rule: Close fasteners that can snag other clothes, but avoid fastening anything in a way that puts unnecessary tension on the garment.

Garment types

How to Wash Different Zippered Clothes

Jackets

Zip-Up Jackets

Close the main zipper before washing to keep the teeth aligned. Empty the pockets, secure any smaller pocket zips and turn the jacket inside out when the care label allows it.

Hoodies

Zip-Up Hoodies

Zip the hoodie before washing so the open teeth do not scrape against T-shirts or other soft garments. A gentle cycle can also reduce stretching and surface wear.

Sportswear

Sports Jackets and Jerseys

Close zippers and wash lightweight performance wear with similar fabrics. Avoid mixing it with rough, heavy items that may increase abrasion or snagging.

Workwear

Uniforms and Work Jackets

Check all front and pocket zippers before the wash. Remove tools, clips and sharp objects from pockets, then follow the fabric and decoration care instructions.

Trousers

Jeans and Zippered Pants

Close the fly zipper before washing. This helps keep the zipper teeth from rubbing against other garments while the heavier fabric moves through the drum.

Delicate

Lightweight or Delicate Clothes

If a delicate item has a small zipper, close it and consider a mesh laundry bag. This gives extra protection from tangling and contact with heavier garments.

Check Pockets Before You Zip

Before closing a jacket or trouser zipper, empty every pocket. Coins, keys, pens and other hard objects can damage both the garment and the washing machine.

Printing and branding

Why Zippers Matter Around Printed Shirts

Silkscreen

Silkscreen Printing

An open metal or plastic zipper can rub against a screen-printed surface during washing. Closing zippers and turning printed garments inside out helps reduce unnecessary abrasion.

DTF

DTF Transfers

DTF prints can be sensitive to repeated scraping along edges and surfaces. Keep nearby zippers closed and avoid overcrowding the washing machine with heavy hardware.

Sublimation

Sublimation Printing

Sublimated colour is inside the polyester fibres, but the fabric itself can still snag. Close zippers on jackets, bags or pants sharing the load with lightweight sublimated shirts.

Embroidery

Embroidery is textured and can catch against exposed zipper teeth. Closing zippers and using a mesh bag for delicate embroidered garments can reduce contact.

Separate Heavy Zippered Garments When Needed

Closing a zipper reduces snagging, but it does not make a heavy jacket suitable for every load. Keep bulky zippered workwear away from lightweight, delicate or heavily decorated shirts when possible.

Why it matters

What Can Happen If You Leave Zippers Open?

Fabric Snags

Exposed zipper teeth can catch loops, loose threads and lightweight fabric as garments move in the drum.

Surface Scratches

Hard zipper teeth and sliders can rub against smooth fabric surfaces and printed areas during agitation.

Zipper Twisting

An open zipper has more freedom to bend and twist, which can place extra stress on the tape and slider.

Tangling

Open jackets or hoodies can wrap around smaller garments more easily, especially in an overloaded machine.

Print Abrasion

Repeated contact between a zipper and a printed T-shirt can add wear that a clothing-only load would avoid.

Delicate Damage

Lace, mesh, knit and other delicate fabrics are more vulnerable to catching on exposed teeth or hardware.

Situation	Best practice	Extra protection
Metal zipper	Close fully before washing	Wash inside out when suitable
Plastic zipper	Close before washing	Use a gentler cycle for lightweight garments
Small delicate zipper	Close carefully	Place the garment in a mesh laundry bag
Broken or jammed zipper	Do not force it	Repair before machine washing when possible

Remember: closing the zipper protects against exposed teeth, but sorting by fabric weight and care requirements is still important.

Step-by-step washing

How to Prepare Zippered Clothes for Washing

Empty Every Pocket

Remove coins, keys, receipts, pens and other objects before closing any pocket or front zipper.

Inspect the Zipper

Check for missing teeth, loose sliders or fabric caught in the zipper. Do not force a damaged zipper shut.

Zip It Closed

Close working zippers fully so the teeth remain together and are less exposed to the rest of the load.

Turn the Garment Inside Out

When the care label allows it, this can reduce rubbing on the outer surface, logos, prints and decorative details.

Sort by Weight and Fabric

Keep bulky jackets and heavy workwear away from delicate T-shirts, mesh, stretch fabric and lightweight sportswear.

Choose the Correct Cycle

Use the temperature and cycle shown on the care label, and avoid overloading the machine so garments can move freely.

Common situations

What Should You Do in Different Loads?

Hoodie

Zip Hoodie With T-Shirts

Close the hoodie zipper and turn it inside out. If the hoodie is thick or has a heavy metal zipper, consider washing it separately from lightweight printed shirts.

Sportswear

Track Jacket With Jerseys

Close every zipper and use a gentle cycle suitable for synthetic fabrics. Avoid rough items that can increase abrasion on performance shirts.

Workwear

Work Jacket With Uniform Shirts

Fasten the jacket zipper, empty all pockets and separate it if it is much heavier or dirtier than the uniform shirts.

Delicate

Zippered Delicate Garment

Close the zipper gently and use a mesh laundry bag. Wash only with compatible lightweight items and follow the care label closely.

Frequently asked questions

Washing Clothes With Zippers FAQ

Should zippers be open or closed in the washing machine?

They are generally better closed. Closing the zipper keeps the teeth together and reduces the chance of them catching or rubbing against other garments.

Should I zip up hoodies before washing?

Yes. Close the zipper, empty the pockets and turn the hoodie inside out when suitable. Follow the care label for temperature and cycle.

Can an open zipper damage T-shirts?

It can. Exposed teeth and the zipper slider may snag, scratch or rub against soft fabric, prints and loose threads as the load moves.

Should I button shirts before washing?

Usually no. Unlike zippers, buttons are commonly left unbuttoned so the wash does not put extra tension on the button and buttonhole.

Should I close pocket zippers too?

Yes, after checking that the pockets are empty. Small pocket zippers can also catch nearby fabric if left open.

What if the zipper is broken?

Do not force it. A broken slider, missing tooth or trapped fabric may worsen in the machine. Repairing the zipper first is the safer option when possible.

Do plastic zippers need to be closed?

Yes. Plastic teeth are less hard than many metal zippers, but closing them still helps reduce snagging and twisting during the wash.

Should zippered clothes go in a laundry bag?

Not always, but a mesh bag is useful for delicate, lightweight or small zippered garments that need extra protection from tangling and abrasion.
