Suede is a delicate form of leather, recognized by its soft, velvety finish known as the nap, and it is highly susceptible to moisture damage. The short answer to whether snow can ruin suede is a definitive yes, especially when the snow turns to slush and mixes with road salt. Unlike finished leather, the open, porous nature of suede fibers allows water and chemicals to penetrate deeply and rapidly, making untreated items vulnerable to permanent discoloration and textural change. Prompt care and preventative measures are necessary to maintain the material’s integrity throughout the winter season.
The Mechanism of Damage
Suede’s porous structure readily absorbs moisture from snow and slush, which begins a damaging physical and chemical process. As the water evaporates, it leaches out the natural oils and tanning agents that keep the fibers flexible. This loss of moisture causes the fibers to become brittle, resulting in stiff, hardened patches and eventually leading to cracking.
The corrosive nature of road salt, typically a blend of sodium chloride or other ice-melting chemicals, presents an even greater threat. When dissolved in slush, these salts are drawn deep into the suede fibers where they recrystallize as the water dries. This process concentrates the salt, leaving behind the characteristic white “salt lines” that permanently etch the surface. The salt residue severely dries out the delicate nap, causing fading, discoloration, and a crusty texture.
Prevention: Protecting Suede Before Snowfall
Proactive treatment is the most effective defense against winter damage to suede. First, gently brush the item with a specialized suede brush to remove dust and lift the nap. This prepares the surface for the application of a high-quality water-repellent spray designed specifically for suede and nubuck.
When choosing a protectant, a fluorocarbon polymer spray is preferred over a silicone-based product. It creates a breathable shield around each fiber rather than coating the material, allowing the suede to breathe and reducing the likelihood of altering its color or texture. Apply the spray in several light, even coats from the distance recommended by the manufacturer, typically around six to eight inches, to avoid saturating the material.
After the initial light coat, the suede must be allowed to dry completely, which can take up to 24 hours depending on the product, before a second coat is applied. This curing time is necessary for the chemicals to fully bond and create a water-resistant barrier that causes moisture and slush to bead up and roll off. For items worn frequently in heavy snow and salt exposure, reapplication of the protectant every few weeks is advisable.
Restoration: Fixing Snow and Salt Stains
If suede is exposed to snow or slush, the primary concern is proper drying, which must be done immediately and away from any heat source. Never place suede near a radiator, fireplace, or in direct sunlight, as high temperatures will rapidly shrink, stiffen, and permanently warp the material. Instead, air-dry the item at room temperature, often with the interior stuffed with unprinted paper or a boot tree to help absorb internal moisture and maintain the original shape.
Once completely dry, salt stains must be treated with a targeted solution to dissolve the mineral residue. A mixture of one part distilled white vinegar to two parts water is an effective, mild cleaning agent, as the acetic acid helps break down the salt deposits. A clean cloth or cotton ball should be lightly dampened with this solution, not soaked, and then gently dabbed onto the stained area.
The salt stain should be blotted carefully, working from the outside of the stain toward the center to prevent the ring from spreading across the nap. After the area has been treated, allow it to air-dry naturally again. Finally, restore the surface texture by using a soft-bristled suede brush or a suede eraser to gently rub the fibers back and forth, lifting and reviving the compressed nap.
