The short answer

Assess the Damage First

Before you try anything, check what kind of water the device came in contact with. Clean water from a leaky pipe is one thing, but floodwater or sewage is another. If the water was dirty, the device may need professional cleaning to avoid corrosion and health risks.

Look for visible signs like water in the screen, a swollen battery, or a burning smell. If you see any of those, do not plug the device in. Take it to a qualified electronics repair shop. They can open it up, clean the inside, and test the parts that still work.

Dry It the Right Way

Power off the device immediately and remove the battery if you can. Take out the SIM card, memory card, and any other removable parts. Wipe off excess water with a soft cloth, then place the device in a dry, warm spot with good airflow.

Do not use a hair dryer or an oven, because heat can warp plastic and damage internal components. A bag of uncooked rice can help absorb moisture, but it is not a perfect fix. The pros use specialized drying equipment and desiccants that work much better for getting water out of tight spaces.

  • Power off the device right away
  • Remove the battery, SIM, and memory cards
  • Wipe off excess water with a soft cloth
  • Let it air dry in a warm, ventilated area
  • Avoid heat sources like hair dryers or ovens
  • Do not plug it in until it is fully dry

What the Pros Usually Do

A qualified electronics repair professional will open the device, inspect the circuit board, and look for corrosion. They often use an ultrasonic cleaner or a solvent bath to remove water and mineral deposits. After cleaning, they test each component to see what still works.

Some parts, like a battery or a charging port, may need to be replaced. Other parts, like the screen or the logic board, might be salvageable if the water did not sit for long. The repair cost depends on the device model, the extent of the damage, and the price of replacement parts.

When Replacement Makes Sense

If the device is old or the repair cost is close to the price of a new one, you might be better off replacing it. Water damage can cause hidden problems that show up weeks later, like a short circuit or a failing battery. A professional can give you a clear picture of the risks.

For expensive items like a laptop or a camera, a repair is often worth trying. For a basic phone or a small appliance, replacement may be the simpler route. Always ask the repair shop for a detailed breakdown of what needs fixing and what it will cost before you agree to anything.

Prevent Future Water Damage

Keep electronics away from sinks, bathtubs, and open windows. Use a waterproof case for your phone if you spend time near water. If you live in Fresno, the hot dry climate means less humidity, but a sudden leak from a pipe or a roof can still happen.

Check your home for leaks regularly, especially under sinks and behind appliances. If you notice a water stain on the ceiling or wall, address it quickly. That kind of damage can also affect your home's structure, so local water damage pros can help with the cleanup and repairs.

  • Keep devices away from water sources
  • Use a waterproof case for phones and cameras
  • Check for leaks under sinks and appliances
  • Fix roof and wall issues early
  • Store devices in dry, elevated spots
  • Know where your main water shutoff valve is

Frequently asked questions

How long does it take for water damage to ruin electronics?

Corrosion can start quickly, especially if the device is powered on. The longer water sits on the circuit board, the more damage it causes. Acting fast to power off and dry the device gives you the right chance, but professional cleaning is often needed.

Can I fix a water-damaged phone with rice?

Rice can absorb some moisture, but it does not remove all the water or the minerals left behind. Those minerals cause corrosion over time. A professional cleaning is more reliable, especially for phones that were submerged or exposed to dirty water.

Is it safe to use a water-damaged device after it dries?

Not always. Even if it turns on, there could be hidden damage like a short circuit or a degraded battery. That can be a fire hazard. Have a professional inspect the device before you use it regularly, especially if it was submerged or exposed to saltwater.
