White shoelaces turn gray faster than the shoes they live in, and once that happens most people just buy new pairs at $4 a set. That gets expensive on a household with kids in sneakers, and the gray problem is fixable in about 20 minutes of active work. Learning how to clean laces properly extends the life of the laces you already own and keeps your sneakers looking new for the full life of the shoe. Different lace materials need different approaches, so the first step is identifying what you are working with.
Identify the Lace Material First
Most modern shoelaces are one of four materials, and the cleaning method differs for each.
- Cotton laces: Common on canvas sneakers like Converse and Vans. Absorbent and prone to permanent yellowing if treated wrong.
- Nylon or polyester laces: Standard on athletic shoes. Resist staining better but build up grime over time.
- Waxed laces: Found on dress shoes and boots. Cannot be machine washed without ruining the wax coating.
- Leather laces: Hiking boots and work boots. Need conditioning rather than washing.
If you cannot tell, do the burn test by snipping a half-inch piece and lighting it. Cotton smells like burning paper and leaves ash. Nylon melts into a hard bead. Waxed cotton smells like a candle. Most household laces are cotton or nylon and can be cleaned with standard methods.
Pre-Treatment for Heavily Soiled Laces
Yellowed or gray laces need a soak before any washing. The pre-treatment lifts deep-set grime that surface scrubbing cannot reach.
- Remove the laces from the shoes entirely. Cleaning them while installed never works and damages the shoe upper.
- Fill a bowl with warm water and add 2 tablespoons of OxiClean Versatile Stain Remover or a similar oxygenated bleach.
- Submerge the laces and let them soak for 30 to 60 minutes. Stubborn yellowing benefits from 2 hours.
- For pure white laces, add 1/4 cup of standard household bleach to a separate soak. Skip this step on colored laces.
- Rinse thoroughly under running water until no suds remain.
Do not use hot water above 120 degrees F. Hot water sets protein-based stains (sweat, food, blood) permanently into the fibers.
Machine Washing Method
The washing machine is the easiest method for cotton and nylon laces, with one critical step that prevents lost laces and damaged machines. Place the laces inside a small mesh lingerie bag or a knotted pillowcase before tossing them in.
Add the bag to a regular load of light-colored laundry. The friction of other clothing helps scrub the laces clean. Use cool to warm water with your standard detergent. Skip fabric softener because it leaves a residue that yellows quickly. Run the wash on a normal cycle.
If you do not have a full load, run them in a sink instead. Machine washing a single small bag wastes water and provides too little agitation to actually clean.
Hand Washing for Stubborn Stains
For laces too dirty for the washing machine, scrub them by hand on a flat surface. This method gives you control over which spots get the most attention.
Lay the soaked laces on a flat surface like a sink ledge or a cutting board. Apply a small amount of dish soap, laundry detergent, or a paste of baking soda and water directly to the dirty areas. Scrub with an old toothbrush in small circles. The bristles get into the lace fibers in a way that hands cannot. Work the entire length of the lace, then rinse under cool running water until the water runs clear.
For really stubborn dirt on white laces, a Magic Eraser works surprisingly well. Wet the eraser, squeeze excess water out, and gently scrub the lace. The melamine foam lifts ground-in dirt without scrubbing the dye out of colored fabrics.
Drying Without Yellowing
How you dry laces matters as much as how you wash them. The dryer is rarely the right answer. High heat can shrink cotton laces noticeably and melt the plastic aglet tips on nylon laces. Air drying is the safer path.
Hang the wet laces from a clothing rack, towel bar, or shower curtain rod with the tips pointing down so any drips run off cleanly. Direct sunlight is your friend here. UV exposure naturally bleaches white laces brighter as they dry, which is why outdoor laundry lines work so well for restoring whiteness. Most laces dry completely in 2 to 4 hours.
Avoid drying on a radiator or near a heater. Concentrated heat causes the lace to dry unevenly and can leave permanent crimps where the lace touched the hot surface.
Cleaning Waxed Laces
Waxed laces need a completely different approach. Soaking them strips the wax coating that makes them durable and decorative. Instead, wipe them down with a slightly damp microfiber cloth and a dab of saddle soap. Work the cloth along the lace in short strokes, applying gentle pressure to lift surface dirt without driving water into the fibers.
For seriously dirty waxed laces, the realistic answer is replacement. A pair of premium waxed laces from Red Wing or Allen Edmonds costs $8 to $15 and is worth the upgrade over fighting decade-old grime.
Restoring the Aglet Tips
The plastic tips on nylon laces fray over time and look bad even when the laces themselves are clean. You can extend their life by carefully heating the frayed end with a lighter for 1 to 2 seconds until the nylon melts back into a smooth shape. Wear gloves and have a cup of water nearby. Do not use this trick on cotton laces because they will catch fire.
For permanent fixes, shrink wrap tubing in 3/32-inch diameter slides over the lace ends and shrinks tight with a quick pass of a hair dryer. A 4-foot length runs $3 on Amazon and rebuilds a dozen pairs of aglet tips.
Replacement Versus Cleaning
At some point laces are past saving. If the lace fibers are visibly fraying along most of the length, or if the aglets have both broken off and the lace ends have unraveled into a fuzzy mess, replacement is faster than rehabilitation. A 54-inch pair of Kiwi flat cotton laces costs $4 at Target and outperforms 30 minutes of scrubbing on truly worn-out laces.
