Soaking shoes? Drying shoes with high heat? Have you made these common mistakes?

Have you ever done something like this: soaking dirty shoes in soapy water for an hour or two; leaving wet shoes on a radiator overnight after a rainy day; or tossing your freshly washed sneakers out in the blazing summer sun, thinking, "The sun will dry them and kill bacteria"... These seemingly natural, well‑intentioned care habits are actually ruining your shoes little by little. And the part that suffers the most is the one thing you can't see but is the most important—the glue.

Most shoes rely entirely on glue to bond the sole to the upper. While this adhesive is flexible, much of it is vulnerable to water, heat, and harsh chemicals. Below, we'll go over the most common mistakes and the correct methods to use instead.

Mistake 1: Soaking shoes in water for a long time – Thinking, "A good soak will make them easier to clean," you drop the whole pair into a basin of water for half an hour or even longer.
Glue's worst enemy is prolonged soaking. Water molecules slowly seep into the adhesive layer, causing it to lose its bonding strength. For older shoes, just one long soak can make the soles start to separate.
Correct method: For local stains, dab a little mild detergent on a damp cloth and wipe the surface. If you need to clean the entire shoe, use a soft brush with a small amount of foam, scrub quickly, try not to let water penetrate the edge of the sole, and immediately blot away moisture with a dry towel afterward.

Mistake 2: Soaking shoes in hot water or soapy water – Believing that hot water cleans faster and that laundry powder is more powerful, you mix hot water with detergent and soak your shoes.
High temperatures soften and deform the glue; when it cools, it becomes brittle and loses elasticity. Strongly alkaline laundry powder corrodes the glue's surface, accelerating aging.
Correct method: Use room‑temperature water and choose a neutral detergent or a specialized shoe cleaner. It's better to wipe an extra time or two than to soak or scald.

Mistake 3: Drying shoes in direct sunlight or on a radiator – After washing, you leave your shoes out in the scorching sun, or in winter you place wet shoes directly on a radiator, or even blast them with a hairdryer on hot. This is the most common and most damaging mistake.
Ultraviolet rays break down the polymers in the glue, making it hard and brittle. The localised high heat from a radiator (often exceeding 50°C) can directly melt the adhesive's structure; once it cools, the glue loses its bonding power. Many instances of sole separation are literally "baked" into existence.
Correct method: After washing, blot away excess moisture with a dry towel, stuff absorbent old newspaper into the shoes (this helps maintain shape and absorbs water), and then let them air‑dry naturally in a well‑ventilated place out of direct sunlight.

Mistake 4: Using strong stain removers or organic solvents – Using alcohol, thinner, or even gasoline to scrub stubborn stains off your shoes.
These organic solvents can directly dissolve or swell the glue, causing the sole to detach almost instantly. Even if you only wipe the surface, the evaporating solvent can seep into the edges.
Correct method: For stubborn stains, gently rub with a small amount of toothpaste or a baking soda paste. If that doesn't work, take the shoes to a professional cleaner. Never use "heavy‑duty" chemicals on your own.

Mistake 5: Scrubbing the edge of the sole repeatedly with a stiff brush – When brushing your shoes, you especially like to scrub hard along the seam where the sole meets the upper, thinking that's where the dirt is worst.
The glue at the seam is already exposed to air and has undergone some aging. The repeated scraping of a stiff brush directly damages the protective film on the adhesive's surface, causing tiny cracks. Once moisture and dust get in, the sole will separate even faster.
Correct method: Use a soft toothbrush with a little cleaning foam, and gently sweep along the gap without scrubbing back and forth forcefully.

Conclusion

In the end, caring for your shoes isn't difficult. The key is to replace "fast and harsh" with "slow and gentle." No soaking, no baking, no sun‑drying, no aggressive scrubbing—that's the secret to keeping your shoes from coming unglued. Next time you're tempted to put your shoes in the blazing sun or scrub them vigorously, stop for a moment and switch to the right method. Your shoes will reward you by lasting much longer.
