Switch the wet phone off and leave it off

Turn it off and stop touching it. Several separate conversations say the thing that kills a wet device is not the water but the electricity running through the water — switching it on, or plugging it in to see, shorts the board at once and permanently — and several cautions rated high say the same in the same breath: do not check whether it works. One caution says the tapping-to-see-if-it-lights-up reflex is what causes the short circuit. Then get the water out that will come out: pull the case, the card tray and anything removable; one account spins the phone in a salad spinner or swings it in a pillowcase to fling the water out of the ports, which is odd and, they say, works. The maker of one popular phone says, in its own support guidance, to tap the phone gently against your hand with the opening facing down and then leave it somewhere dry with some airflow — and it says not to push cotton buds or paper towel into the connector, not to use compressed air, and not to apply heat. That contradicts one account here who reaches for canned air; another caution says a tilted can sprays freezing liquid onto the board, so this page sides with the maker. One evenly split exchange is about which direction to move air at all: one says a fan, straight at it, taken apart if you can; the other says never blow into the holes, because you raise the pressure inside and push water further in — hang it so the water drains from the biggest opening and move air across the surface instead. Why the hurry: several separate conversations say the liquid rarely destroys anything by itself; the corrosion that follows does, the white and green crust that grows on the contacts from the impurities in the water, and one caution rated high says that can begin within a few hours. Which is why speed matters more than the choice of desiccant, and why what you do in the first minute is most of the outcome.

Not rice, and the people here have had this argument in many separate conversations, so here is the whole of it. Many conversations say the rice is a mistake: it does not pull water out of a sealed device, it leaves starch dust and fragments in the ports, and others say that any phone that came back after rice came back because of the days that passed, not the grain. The maker of one popular phone now says the same — no rice, because the particles damage the phone. But the people who defend it are not fools, and this page carries them: in one conversation, rice edges silica: slightly more accounts say rice is the thing you actually have at eleven at night while silica is the thing you don’t; in another the split is even; in another, a few say rice is terrible and gross while more say it is a valid fallback that has saved their phones; several objecting accounts say rice is ‘not as ideal’, not useless. The decider the people here agree on is simply what is in the house, and one caution says every rice success story is confounded by time. What settles the argument for this page is who is saying what: across more than one conversation the repair technicians — the people who open the phones afterwards — say rice fails to stop corrosion and clogs the ports, and the accounts for rice are anecdote. One correction is owed to the anti-rice side too: the claim that rice leaves ‘crystals’ inside a phone was called nonsense by most of an exchange, and the people here who dislike rice dislike it for the dust and the delay, not for crystals. Silica gel, then: several conversations say it is the better desiccant, and the catch is the one more than one conversation names — the packets from a shoebox are already full of the air’s moisture and do nothing until they are dried out again. One correction gives the fix: a low oven for the packets, and a caution rated high says the phone never, ever goes in with them. One account buys unscented silica cat litter as a bulk source; more than one conversation saves the packets from every purchase into a jar, and one caution says the jar has to be tight or they saturate in the cupboard. Then the method several accounts describe: phone and dry silica in a sealed box for two days, and cautions rated high say do not open it to look, because you let the moisture back in. Finally the fan, which is where the strongest evidence in these conversations sits and the fewest people. Several accounts say moving air is orders of magnitude faster than any passive desiccant, and one correction says the same against rice by name; the argument that matters, split unevenly across conversations, is silica-in-a-box against a fan, and the accounts’ own decider is whether you can open the device — a fan across a closed phone is a fan across glass. One account uses a vacuum cleaner at the ports and calls it better than a fan; another says a vacuum killed motherboards with static, and a contraindication says to be cautious with vacuums for that reason. This page’s own ordering, from the accounts: off, tapped out, moving room-temperature air, silica if you have dry silica, two days, and rice only if the alternative is the bathroom floor. Warm room air is fine — an electrical engineer in one conversation puts the ceiling around body temperature — and heat is not: one account dried a phone with a heat gun on low and this page refuses to repeat it.

Only for a sugary spill, only on the board, and probably not by you. Several separate conversations say high-strength isopropyl alcohol displaces water and evaporates fast, which is true and is why repair shops use it; one evenly split exchange is the whole argument — one side says it dissolves the adhesives and silicone seals a modern phone is held together with, the other says it is for cleaning corrosion off an opened board with a brush, never for dunking a sealed phone. A contraindication says the same: no submersion for a device with glued seals. Cautions rated high sharpen it: the rubbing alcohol sold in a pharmacy can be a third water plus a bitter additive, and one correction says you will rarely find better than 91 per cent in a pharmacy; another correction says contact-cleaner spray is not the safe substitute it sounds like, because it evaporates too fast to carry sugar away. The one case the accounts make for alcohol is the drink that was not water: more than one account says a phone dropped in something sugary needs the sugar dissolved before it hardens on the contacts, and one caution says that is the only time to reach for it. One account suggested flushing with distilled water instead and was corrected more than once: it becomes conductive the moment it touches the dirty board, and one caution rated high says it is aggressive to the copper besides. If you are not going to open the phone — and for a sealed, glued, modern device one account says the right move is not to — none of this is for you; the service centre is.

It is on. That is not the same thing, and the people here are honest about it. Several separate conversations say the liquid rarely kills a device on the spot; what kills it is the corrosion that grows afterwards, and one correction points out the uncomfortable part — the impurities in the water keep corroding the contacts even with the device off and even once it feels dry, so ‘it works now’ tells you about now. One caution calls a once-wet phone a ticking time bomb: the camera or a button fails later. So the first thing you do with a resurrected phone is back it up, today, and the second is decide whether it is worth a technician cleaning the board before the crust finishes the job. Two smaller things the accounts mention: some phones detect moisture in the charging port and refuse to charge by cable until it is dry — one account says it re-enables itself, and the maker’s guidance says that can take up to a day, so charge wirelessly if you can and do not force it; and more than one conversation plays a low tone through the speaker to shake water out of it, which is a real trick and not a repair. If the device is under warranty, the accounts say the maker is the first call, not the fan; one caution notes that opening it yourself can cost the cover.

A freezer bag, for the beach, the boat and the rain — with one word changed. Many separate conversations say a zip-seal freezer bag or a bin bag is a cheap, effective barrier for a phone or laptop against sweat, rain, sand and splashes, and that a touchscreen works through it; one account double-bags and sucks the air out with a straw so the screen presses flat. The word to change is waterproof. Several corrections say the bag is water-resistant, not waterproof: it will fail if it goes under, or under pressure, and cautions rated high say every zip bag eventually leaks and to test one before trusting a phone to it. Exchanges carry the argument: a close split on whether a bag done properly is enough, and an even one on using one in the shower for podcasts — one side says it works fine, the other says people have carried broken phones into repair shops after doing it; the decider both give is what the phone is worth to you and what you will do if the bag fails. Cautions rated high add the boating rule: a bagged phone sinks, so put air or something buoyant in the bag, and one account ties a floating trinket to keys and phone for the same reason. Several cautions say a phone working hard inside a sealed bag overheats, so no video or games in there. For anything more than splashes, one account buys a purpose-built waterproof case rather than risking an expensive phone on a cheap bag, and another notes that one account notes some phones sell with built-in water resistance — with one account’s reminder that resistant means it survives a stated depth for a stated time, not that it is sealed. The cheerful small use: one account keeps the phone in a bag while working on the car so the manual stays readable and the screen stays clean.
