How to Use a Wet USB Cable: Can It Be Saved?

Recently, I had a comical mishap that involved my coffee and a USB cable. While I was clearing up my desk, I inadvertently plunged the tip of the USB cable into my coffee cup. “Looks like my coffee decided to give me a jolt today,” I chuckled as I pulled it out, inspecting the connector for any signs of the flavorful brown liquid.

Despite the humor of the situation, it sparked a thought: Could I still use my USB cable immediately, or had I rendered it useless? Uncertain of what to do, I embarked on a little investigation. Here’s what I discovered…

Understanding Wet USB Cables

While many USB cables boast a degree of water resistance, think of it in terms similar to a cheap 1980s watch—okay for a few splashes, but not built for immersion. Submerging them is typically a bad idea.

The connector is the most at risk, as it’s exposed and lacks protective casings. If your cable happens to get wet, it’s crucial to power off your device immediately and disconnect it from any power sources as soon as possible.

It’s also essential not to rush into using the cable again; let it dry for at least an hour to prevent any moisture—be it water or coffee—from reaching your device’s USB port or damaging the cable. There are a few techniques to expedite the drying process.

How to Effectively Dry Your Cables

If your cable has gotten wet, begin by drying it with a cloth. Run your hand gently along its length. If any liquid has pooled inside the connector, shake it lightly to dislodge excess droplets. Then, use a tissue or a microfiber cloth to carefully soak up any remaining moisture inside.

I tried these methods on my soaked USB cable, and to my relief, it functioned perfectly when I plugged it back in.

Need a Quick Fix? Consider This…

A hairdryer can be a game changer for drying out a wet connector, but some precautions are necessary to avoid damaging your cable with heat.

First, always set the hairdryer to its lowest heat setting.

Additionally, maintain a safe distance of about 14 inches between the cable and the hairdryer’s nozzle to ensure a steady stream of warm air without overheating the cable or its connector.

Using a hairdryer can dry your cable sufficient enough for use in as little as 15 minutes, as opposed to the hours it might take otherwise. Just remember to ensure it’s completely dry before reconnecting it.

In conclusion, while most USB cables can withstand a bit of splashing or brief submersion in liquids, caution is key. Always dry them thoroughly before reusing, to safeguard your devices from potential damage.
