TL;DR
Gray shoelaces clean up with a warm soak in soapy water, a firm rub between your hands or with a brush, and a full rinse, which usually takes about thirty minutes of soaking plus five minutes of work. A mesh laundry bag lets you machine wash them safely, but the dryer will melt the plastic tips.
Why Do Shoelaces Go Gray?
Laces sit right at the top of the shoe where dust, road grit, and skin oils land. They are usually cotton or polyester braid, which has an enormous amount of surface area for that soil to lodge in.
The gray is not one stain. It is thousands of small particles caught in the weave plus a film of body oil that holds them there. That is why a quick rinse does nothing and a soak plus friction works.
Laces also pick up dye from the shoe itself and from socks, especially in the first few washes of a new pair. That kind of discoloration is dye transfer rather than soil and does not always come out.
Always Unlace First
Take the laces completely out of the shoe. Cleaning them in place is the most common mistake, because you cannot reach the sections that sit under the eyelet row, and those are exactly the dirtiest parts.
Unlacing also lets you clean the tongue and the eyelet stay properly, which is where grit collects and grinds at the shoe.
Take a quick photo before you unlace if your shoe has an unusual lacing pattern. It saves five minutes of puzzling later.
How Do You Hand Wash Shoelaces?
Soak the laces in warm water with a small amount of laundry detergent or dish soap for about thirty minutes, then rub them briskly between your hands or scrub them with a soft brush on a flat surface. Rinse until the water runs clear and hang them to air dry. Friction is what actually removes the gray.
Rubbing the lace against itself works better than a brush for round laces, because it flexes the braid open and lets water reach the core.
For flat laces, lay them on a cutting board or a countertop and scrub with a soft brush. Turn them over and do the second side.
A second short soak after the first scrub often lifts noticeably more soil. Change the water; reusing gray water just redeposits soil.
Can You Machine Wash Shoelaces?
Yes, in a mesh laundry bag or a zipped pillowcase. Loose laces wrap around the agitator, snake into the drain pump, and get lost, and the mesh bag prevents all of that. Wash on a normal cycle with your regular load, then air dry.
Never put laces in a clothes dryer. The plastic or metal tip at the end, called an aglet, is usually heat-sealed plastic that softens and deforms. A lace without an aglet frays immediately and becomes nearly impossible to thread.
Tie the two laces together loosely at one end before bagging them so they do not tangle into a knot you have to fight later.
What About Whitening Very Dingy White Laces?
An oxygen bleach soak is the safest whitening step for white cotton laces. Dissolve it in warm water per the package instructions, soak for one to several hours, then wash and rinse normally. It is gentler on fibers than chlorine bleach and does not yellow rubber.
Chlorine bleach is a poor choice here. It weakens cotton fibers, so laces snap sooner, and any splash on the shoe can yellow a rubber midsole permanently. That yellowing mechanism is explained further in our guide to white sneakers without yellowing.
Whatever you use, never mix cleaning products. Chlorine bleach combined with ammonia or with an acid such as vinegar releases toxic gas, and there is no laundry benefit that justifies it. Work in a ventilated space and use one product at a time.
Colored laces should not get any bleach at all. Test any whitening product on a short section first, because dye behavior varies enormously.
How Should Laces Dry?
Hang laces over a rod, a hanger, or a towel bar so air circulates. They dry in two to six hours depending on thickness.
Keep them out of direct sun if they are colored, since ultraviolet light fades dye. White laces are less affected but still dry fine in the shade.
Do not put them back in a damp shoe. A wet lace threaded into a wet shoe keeps both damp longer and encourages odor.
When to Replace Instead of Clean
Replace laces when the aglet has broken off and the end has frayed, when the braid has thinned or split anywhere along its length, or when the gray does not lighten after two proper wash attempts.
Replacement laces are inexpensive, generally in the $4 to $12 range at retail for a common length, and new laces make an old shoe look dramatically better for very little money.
Measure the old lace before buying, or count the eyelet pairs. Getting the length wrong is the usual reason a new set sits in a drawer.
For the whole category of footwear and everyday carry, our shoe and bag cleaning guide covers the same material-first logic, and canvas uppers have their own quirks explained in canvas shoes without water stains.
Small textile items like laces respond to the same treatment as any fabric in a house: soak to loosen, agitate to release, rinse to remove. It is the same sequence a crew uses on soft surfaces during house cleaning services, just at a much smaller scale.
FAQ
Can I wash shoelaces in the washing machine?
Yes, if you put them in a mesh laundry bag or a zipped pillowcase first. Loose laces tangle around the agitator and can reach the drain pump. Wash on a normal cycle with a regular load, then air dry. Do not use the dryer, because heat deforms the plastic tips.
Why are my white shoelaces still gray after washing?
Gray usually needs friction, not just detergent. Soak the laces in warm soapy water for about thirty minutes, then rub them briskly between your hands or scrub them with a brush, and repeat with fresh water. An oxygen bleach soak helps on white cotton laces.
Should I use bleach on white shoelaces?
Oxygen bleach is the better choice. Chlorine bleach weakens cotton fibers so laces break sooner, and any splash can permanently yellow a rubber midsole. Never mix bleach with other cleaning products, and skip bleach entirely on colored laces.
How do I keep the plastic tips from falling off?
Keep laces out of the dryer, since heat softens and deforms the sealed tip. Avoid yanking a stuck lace through an eyelet. If a tip does come off, a tight wrap of clear tape or a dab of clear nail polish on the frayed end restores enough stiffness to thread it.
How long do shoelaces take to air dry?
Two to six hours hung over a rod or towel bar, depending on thickness and humidity. Round athletic laces with a thick core take the longest. Do not put damp laces back into a shoe, because it keeps the shoe wet longer and encourages odor.
Is it worth cleaning laces or should I just replace them?
Clean them if the braid is intact and the tips are on. Replace them if the ends have frayed, the braid has thinned or split, or two proper washes have not lightened the gray. New laces typically run $4 to $12 a pair and refresh an older shoe noticeably.
