Yes, credit cards can get wet, but they usually still work
A wet credit card is almost never ruined. The magnetic stripe and chip that store your account information are designed to survive water exposure. You can dry it off and use it normally within hours. The real risk is not the card itself — it is what you do while it is wet, and what happens if the card issuer suspects fraud when you suddenly cannot use it.
Credit cards are made from PVC plastic laminated with protective layers. Water does not dissolve plastic or erase the magnetic stripe data. Chip cards are even more resilient because the chip is embedded under a protective coating. A card that has been soaked in a pool, dropped in a puddle, or run through the washing machine will dry out and function again.
The one genuine risk is corrosion. If a card sits wet for days without drying, or if it is exposed to saltwater repeatedly, the metal contacts on the chip can corrode. This takes time — hours or days of continuous moisture, not a single soaking. A card that gets wet once and dries within a few hours faces almost no corrosion risk.
Key Takeaways
- Water does not damage the magnetic stripe or chip on a credit card, so a wet card will work again once it dries.
- Dry your card with a soft cloth and let it air-dry for a few hours before using it again to avoid any corrosion risk.
- If your card stops working after getting wet, contact your card issuer to report the problem and request a replacement.
- Your card issuer may flag unusual activity if you suddenly cannot use your card and then report it missing, so call them promptly if water damage occurs.
How to dry a wet credit card safely
The process is straightforward. Remove the card from water as soon as you notice it is wet. Pat it dry with a soft, lint-free cloth — a microfiber cloth or paper towel works well. Do not rub hard or use heat from a hair dryer, because friction and high heat can damage the protective coating on the chip.
Lay the card flat on a clean, dry surface and let it air-dry for at least two to four hours before using it. You can stand it upright or lay it flat; either works. Avoid placing it near direct heat, sunlight, or in a closed container where moisture cannot escape. Once it feels completely dry to the touch, it is safe to use in an ATM or card reader.
If the card was in saltwater, freshwater, or any liquid other than plain water, rinse it gently under cool running water first to remove any residue, then pat it dry and air-dry as described above. Saltwater and sugary drinks can leave deposits that may interfere with the card reader over time, but rinsing removes most of this risk.
When a wet card stops working and what to do
Most wet cards work fine after drying. If yours does not, the problem is usually one of two things: the card reader is having trouble reading the wet card, or the card has genuine damage. Try using the card at a different ATM or store first. Sometimes the problem is the reader, not the card.
If the card still does not work after it has dried completely, contact your card issuer. Tell them the card got wet and stopped working. They will either troubleshoot over the phone or send you a replacement card. Replacement cards usually arrive within five to ten business days, though some issuers offer expedited shipping for a fee.
Do not wait to call if your card is not working. The longer you wait, the more likely your issuer is to suspect fraud when you report the card missing or damaged. A prompt call creates a record that the card had a legitimate problem, which protects you if unusual activity appears on your account later.
Protecting your card from water damage in daily life
The easiest protection is a waterproof wallet or card holder. These are inexpensive — usually between five and fifteen dollars — and keep cards dry during rain, at the beach, or around water. Many are slim enough to fit in a pocket or bag without adding bulk.
If you do not have a waterproof holder, keep your card in an inside pocket of a jacket or bag rather than a back pocket or outer pocket. This reduces the chance of accidental water exposure. At the beach or pool, leave your card at home or in a locker rather than carrying it in your pocket.
For people who work around water — construction workers, landscapers, lifeguards — a waterproof holder is worth the small cost. It protects not just your credit card but also your ID and other cards. Some people also keep a backup card at home in case their primary card is damaged and needs replacement.
The difference between water damage and normal wear
Card issuers replace damaged cards for free, but they distinguish between water damage and normal wear. A card that has been wet once and dried is not considered damaged — it is just a card that got wet. A card that has visible signs of damage — peeling plastic, discolored areas, or a visibly corroded chip — may be flagged as damaged.
This distinction matters because some issuers charge a fee for replacement if they believe you damaged the card through carelessness. In practice, most issuers do not charge for a single water incident, especially if you call promptly and explain what happened. They charge fees mainly for cards that are repeatedly damaged or show signs of abuse.
If your card issuer offers a replacement for free, take it. If they quote a fee, ask whether the fee applies to water damage or only to other types of damage. Many issuers waive fees for the first replacement or for accidental damage. A quick phone call can clarify the policy before you commit to paying.
Chip cards versus magnetic stripe cards in water
Chip cards are more water-resistant than older magnetic stripe cards because the chip is embedded under a protective coating. However, both types survive water exposure. The magnetic stripe is made of iron oxide particles bonded to the card with a resin coating — water does not dissolve this coating or erase the data.
Chip cards have an additional advantage: they can be read even if the magnetic stripe is slightly damaged or wet. If you have an older card with only a magnetic stripe and no chip, it will still work after drying, but it may be more vulnerable to corrosion if it stays wet for extended periods. Most cards issued today have both a chip and a magnetic stripe, so this is less of a concern.
If you have an older card with only a magnetic stripe and you frequently work around water, consider requesting a replacement card from your issuer. Newer cards with chips are more durable and also offer better fraud protection, so the replacement is worth doing anyway.
What to do if your card is lost in water
If your card is lost in water — dropped in a river, left in a flooded car, or submerged in a way you cannot recover it — treat it as a lost card. Call your card issuer when ready and report it lost. They will cancel the card and send a replacement. Do not wait to see if the card turns up; canceling it when ready protects you against fraud.
Your issuer will ask when you last used the card and when you discovered it was missing. Be honest about the water incident. This creates a record that explains why the card disappeared and protects you if charges appear on your account before the card was canceled.
Once you report the card lost, you are not responsible for fraudulent charges made after the report, even if someone finds the card and tries to use it. Your liability for charges made before you reported it lost depends on your issuer's policy and how quickly you called, but most issuers limit your liability to fifty dollars or zero dollars if you report the loss promptly.
Frequently Asked Questions
Can I use my credit card while it is still wet?
No. Wait until the card is completely dry before inserting it into an ATM or card reader. Using a wet card can damage the reader or cause the card to stick. Dry it thoroughly first, then use it normally.
Will my credit card work if it goes through the washing machine?
Yes, in almost all cases. Washing machine water is not hot enough to damage the card, and the agitation does not harm the magnetic stripe or chip. Dry it with a soft cloth and let it air-dry for a few hours, then use it as normal.
Do I need to replace my card if it gets wet once?
No. A card that gets wet once and dries completely does not need to be replaced. It will work normally. Replace it only if it stops working after drying, or if it shows visible signs of damage like peeling plastic or discoloration.
What if my card gets wet and then stops working weeks later?
This is unlikely but possible if the card was exposed to saltwater or another corrosive liquid and the chip corroded over time. Call your card issuer and explain that the card was wet weeks ago and has now stopped working. They will send a replacement. Keep a record of when the card got wet in case your issuer asks.
Can I speed up the drying process with heat?
No. Avoid hair dryers, ovens, or direct sunlight. High heat can damage the protective coating on the chip or warp the plastic. Air-drying at room temperature is the safest method and takes only a few hours.
