If you have a water-damaged phone, there are a few steps you can take to remove the excess moisture. You can use a paper towel or a washcloth to dry the phone. Make sure to get into all the nooks and crannies, including the headphone jack and SIM slot, so that the water is completely removed from the phone. Ideally, you should leave the phone in the rice overnight, though you should allow longer if you find the water is really bad.
If you aren’t comfortable blowing out the water, you can also use a mechanical air compressor set to a low psi setting. The air should be blown across the phone’s surface and into the ports to remove all of the water. Avoid using higher psi, as this can cause further damage to the phone’s internal components. If you don’t have a mechanical air compressor, you can also try a blow dryer.
First, you should remove the case and external components of the phone. Once you’ve taken out the external components, wipe them down gently with a clean cloth. Do not shake the phone, as this can cause the water to move further inside. You can also use compressed air to blow out any remaining water that has built up in the phone’s case. Lastly, make sure that the phone is properly ventilated, as moisture can cause deterioration of internal components.
