Wet cell phone saved after four days

We had a customer call us a few weeks ago that had there family cell phone fall in to the tide pools at the beach. She called us to see if her wet cell phone could be saved even though it had been four days since it originally got wet. Since she had not pushed any buttons I let her know that DRY-ALL could save her wet cell phone. We told her to rinse the phone with distilled water to get all of the salt water off of the inside of the phone. After doing that we told her to place her phone in DRY-ALLs Wet Cellular Phone Emergency kit and leave it for 48hrs. She called this morning to let us know that her cell phone works great now and DRY-ALL saved her wet cell phone.
