Leather Care & Weather
Does Water Ruin Leather?
Water alone needn't ruin leather; heat-drying, storing it damp and leftover salt can. See what water does by leather type and what you can still fix.
Water on its own doesn't have to ruin leather; what you do next decides it. The sources warn against three things: drying it with heat, putting it away damp, and leaving winter salt on it. Let wet leather dry at room temperature, and never put it in a dryer.
Part of our leather care and weather guide.
What water does, by leather type
According to the BLC Leather Technology Centre, leathers react to water in different ways:
Not sure which you have? Check the care label.
International Leather Club explains why a water mark forms: water is drawn into the fibers, dissolves salts, oils, dyes and tanning agents, and leaves them concentrated near the surface where it dries. The swatches run under a tap in the video only show the staining; this is not a cleaning method, and the advice on this page still applies.
| Leather | What water does | Goes back to normal? | Fact |
|---|---|---|---|
| Aniline | Soaks in and darkens the leather | The source does not say | – |
| Suede and nubuck | Darkens while the nap is wet | Should dry back to the original color | – |
The three ways water does lasting harm
Damp air does slow harm as well. The Canadian Conservation Institute links relative humidity above 65% to mould and to breakdown of the leather fibers.
If a white bloom appears after leather dries, don't assume it's mould. Salts from sweat and fatty residue can look the same. For timing, see how long leather takes to dry.
| Cause | Why it matters | What to do instead | Fact |
|---|---|---|---|
| Drying with direct heat | BLC and the store's care guide both rule out hair dryers, radiators and clothes dryers | Dry it naturally at room temperature | – |
| Putting it away damp | Mould can grow after 2 days at 90 to 100% humidity, 10 days at 80% and 100 days at 70% | Let it dry fully in a ventilated room first | – |
| Salt left behind | Winter salt stains leather | Wipe with a clean, damp cloth and let it dry naturally | – |
Can water damage be fixed?
You can limit the damage:
- Blot the water with a clean cloth as soon as you can.
- Dry it promptly but without heat. The conservation advice is to dry wet leather as quickly as possible, but by air, not with a heater.
- Take any water stain that remains to a professional leather cleaner.
Suede and nubuck should recover their color once dry. Whether darkening on aniline leather fades is not covered by the sources we found. A leather specialist is the safer judge. For leather that has already cracked or hardened, restoration is covered at mumiay.com.
Before the next wet day, see can you wear leather in the rain. For everyday care, see how to care for a leather coat.
When you buy leather, ask about the hide and the finish. Leather Collection coats, for example, come in cowhide, sheepskin or goatskin.
