What to Do When Your Touch Screen Gets Wet
As a touch screen supplier, I've encountered numerous questions from customers regarding touch screen maintenance and troubleshooting. One of the most common issues is what to do when a touch screen gets wet. In this blog post, I'll share some practical advice on handling this situation based on my experience in the industry.
Understanding the Impact of Water on Touch Screens
Before we delve into the solutions, it's important to understand how water affects touch screens. Touch screens work by detecting electrical signals. When water comes into contact with the screen, it can disrupt these signals, leading to various problems. For capacitive touch screens, which are the most common type today, water can cause inaccurate touch responses, unresponsive areas, or even complete malfunction.
Immediate Actions
If your touch screen gets wet, the first step is to act quickly. Here's what you should do:
-
Power Off the Device
The moment you notice that the touch screen is wet, turn off the device immediately. This helps prevent short - circuits, which can cause permanent damage to the internal components. For example, if it's a tablet or a smartphone, press and hold the power button until the device shuts down. -
Remove the Device from the Water Source
If the device is still in water, take it out right away. Avoid leaving it submerged for any longer than necessary, as prolonged exposure can increase the risk of damage. -
Wipe the Surface
Use a soft, dry cloth to gently wipe the surface of the touch screen. Make sure to remove as much water as possible from the screen and the edges of the device. Be careful not to apply too much pressure, as this could scratch the screen.
Drying the Touch Screen
After the initial steps, the next crucial part is to dry the touch screen thoroughly. Here are some methods you can use:
-
Air Drying
Place the device in a well - ventilated area with good air circulation. You can leave it on a table or a countertop. Avoid direct sunlight, as excessive heat can damage the screen and other components. Air drying may take several hours to a day, depending on how wet the device is. -
Using a Desiccant
Desiccants are substances that absorb moisture. You can use silica gel packets, which are commonly found in shoe boxes or electronic packaging. Place the device and the silica gel packets in a sealed plastic bag. The silica gel will draw the moisture out of the device over time. Another option is to use uncooked rice. Although it's not as effective as silica gel, it can still absorb some moisture. Put the device in a container filled with rice and leave it for at least 24 hours. -
Avoid Using Heat Sources
Do not use a hair dryer, heater, or any other heat source to dry the touch screen. High temperatures can warp the screen, damage the internal components, and even cause the adhesive holding the screen in place to melt.
Testing the Touch Screen
Once you believe the device is dry, it's time to test the touch screen. Power on the device and check if the touch screen is functioning properly. Try tapping on different areas of the screen, swiping, and performing other touch - based actions. If the screen is still unresponsive or has inaccurate touch responses, you may need to take further steps.
When to Seek Professional Help
If the touch screen is still not working after drying, it's advisable to seek professional help. A technician can open the device, inspect the internal components, and determine if there is any water damage that needs to be repaired. In some cases, they may need to replace certain parts, such as the touch screen digitizer.

-
Use a Protective Case
A good quality protective case can provide an extra layer of protection against water and other forms of damage. Look for cases that are waterproof or water - resistant. -
Be Careful in Wet Environments
Avoid using touch - screen devices in areas where they are likely to get wet, such as near swimming pools, in the rain without proper protection, or in the bathroom while taking a shower. -
Regular Maintenance
Keep your touch screen clean and dry on a regular basis. This helps prevent the build - up of dirt and moisture, which can affect the performance of the screen.
