Kann man elektronische Geräte wirklich mit Reis trocknen?
Mit dem Wasser in elektronischen Geräten ist es ungefähr so wie mit Pfannkuchenteig: Wenn du sofort zum Lappen greifst, lässt er sich leicht abwischen. Aber wenn du länger wartest, hast du ein Problem. Das Gleiche gilt für Wasser in elektronischen Geräten.
Wenn du ein Handy in Reis legst, passiert genau dasselbe, wie wenn du gar nichts unternimmst. Alles, was es bringt, ist das Gefühl, dass du etwas unternommen hast. Denn die Korrosion beginnt sofort, wenn Wasser ins Innere des Geräts dringt. Manchmal betrifft sie wichtige Bauteile, manchmal nicht. Wenn du es schaffst, es nicht anzuschalten, bis es getrocknet ist - ob es jetzt auf dem Tisch liegt oder in einer Schüssel mit Reis -, kann es sein, dass du Glück hast. Wenn dein Handy zufällig in der Reisschüssel lag, denkst du vielleicht, dass der Reis es gerettet hat. Hat er aber nicht. Auch wenn das Handy scheinbar nicht beschädigt wurde - kleine Lötverbindungen im Inneren sind oxidiert und dadurch schwach und brüchig geworden. Die Korrosion breitet sich dann weiter im Handy aus. Dass es überhaupt noch angeht, hat nichts mit dem Reis zu tun - du hattest einfach nur Glück. Vorerst jedenfalls.
Also was hilft wirklich, wenn dein Gerät nass geworden ist? Auch wenn es unlogisch klingt: Versuche nicht, es zu trocknen!
Wie du dein Handy ohne Reis trocken kriegst
Das Allererste, was du tun solltest, ist, das Wasser zu verdrängen - genauer gesagt, all die leitfähigen Inhaltsstoffe des Wassers. Das funktioniert am besten mit 90 %-igem Isopropyl-Alkohol und einer Zahnbürste. Öffne dein Gerät so bald wie möglich, baue den Akku aus und fang an zu schrubben. Bedecke das gesamte Motherboard mit Alkohol und säubere es sorgfältig mit der Zahnbürste. Erst dann solltest du es trocknen lassen, und erst dann kannst du schauen, woran du bist. Indem du das Wasser verdrängst, bevor es trocknen kann, wischst du praktisch den Pfannkuchenteig ab, solange er noch flüssig ist.
Klar klingt es verlockend, das Handy einfach in Reis zu legen - und vielleicht funktioniert es nachher auch wieder, wer weiß. Es wäre so viel einfacher, als es auseinanderzunehmen und ordentlich zu säubern.
Aber du wirst niemanden finden, der in der Reparaturbranche arbeitet und Reis bei Wasserschäden einsetzt. Im Gegenteil - wahrscheinlich hat er oder sie schon zahlreiche Geräte vor sich gehabt, die kaputt waren, gerade weil sie in Reis gelegt wurden.
An alle Reparatur-Profis da draußen: Bitte teilt eure Bilder davon, wie ein Smartphone oder ein anderes elektronisches Gerät wirklich aussieht, wenn es aus dem Reisbad kommt. Ein Bild sagt ja bekanntlich mehr als tausend Worte - vielleicht hilft das, um allen klarzumachen: Reis hilft nicht bei Wasserschäden.

Hi, ok fair enough, but it has worked for me before . I don't open up the items, all I do is place them in the rice then place them it in direct sunlight and under the light globe. After that I open them and see how things look. In the bebops case all looked good so I fired it up.

It did not work. You think it worked because you did something. You could have wrapped up your phone in Toilet paper and probably would have received the same results. Be sure to use the extra absorbancy kind. What worked was evaporation, but the corrosion will remain.

All very true. And if the loquid contained any amount of sugar, you actually need to first scrub and rince the parts with demineralized water as sugar is almost not soluble in alcohol. Then you rince with alcohol to wash out the demineralized water so it will dry properly, as it could leave moisture in small parts otherwise.
And you can check for the water marks inside. if they haven’t change color than you’re lucky and liquids most probably didn’t get in.
I saved a few devices this way (scrubbing with demineralized water and/or alcohol, not the rice). The rice is actually worst than letting it dry vertically. Depending on the rice you use, and how you put the device in, you can get rice dust particles inside the device, which will get stuck to the water droplets, and potentially burn up when you power on the device depending on where the are.
But like you said, scrubbing still is not magic, if you waited too long, tried to turn on your devices, or dropped it in some peculiar mix, no amount of scrubbing will do. I once forgot an iPhone 5 in the washing machine, turned on (sleep mode). Let’s just say the full cycle with soap, banging, spinning (too make sure everything got real wet. Let’s just say that one never walked again. Who knew metal could get so green so fast…

Almost every time we have had a customer bring a phone that has been in contact with rice, there is a piece stuck in the charge port and the headphone jack. So even if rice was able to dry your phone, you are possible damaging your phone by introducing foreign objects into the exposed ports.

Just thinking about the amount of dust in rice makes me cringe when a person says that they put their phone in rice

You don’t want to dry the water that’s allowing for corrosion? What kind of nincompoop would ever believe that?
Yes, in an ideal world displacing the water and ions that allow for corrosion, then drying it off is the procedure, but good luck doing that on a wet device if you are not a professional with tools and isopropylic at your disposal.
Rice works by absorbing moisture from the air around it - surround a device in a dessicant and most of the remaining water will dry faster. Dissicants. And it is A LOT better than letting it soak .
Isopropyl alcohol is also relatively safe, but that relatively gives room to A LOT, from damaging screens, coatings, paint, and even some lower-end rubber used in some, rather bad tactile switches, oh, and most adhesives, as in the ones holding your screen to the rest of the device adhesives. Also, good luck displacing that tiny drop of water unless you open up your device (do you already have the tools at your disposal? what about the ones needed to reassemble it?).

Except rice is a horrible desiccant, there are much better options.

How about an iphone that you can not open up…. would placing the whole thing in a baggy full of rubbing alcohol work? (Turned off of course)

It would destroy the display.

Good report, thanks, yet.. how to open an iPhone?

There’s a guide on how to open and repair every model of iPhone on ifixit’s website. If you don’t believe me, i’ll show you.

My iPhone 8 went through the wash cycle of my Fischer Paykel washer. It works, should I be worried? This washer uses very little water, only enough to wet the clothes, no soaking.

this happened to me just yesterday I was so confused and searched different websites
what I did was to squeeze in some mattress foam into the headphone jack for 20 MINS then I removed it and shook my phone vertically against the palm of my hands and suddenly it started working again, and the microphone too, glory be to God

Your very BEST bet is that extended warranty just sayin

Corrosion is not instant. Please give me what your definition of corrosion is… Here are the definitions i have found online: “destroy or damage (metal, stone, or other materials) slowly by chemical action” “(of metal or other materials) be destroyed or damaged slowly by chemical action” “destroy or weaken (something) gradually.“

i used to put any electronics that got wet into a speedvac (a vacuum desiccator) and that has saved more than 50%. pre drying with 100% iso is also a really good idea.

For those that think, "but it worked for me," beware of confirmation bias. Being consistently lucky is different from having a working mephod.
Tang Tang - Antwort
its not fool proof.... the water has to NOT destroy components for it to work. Thats just common sense
Otherwise, this works 100% of the time.
Its ok to be wrong, just as long as you know. You are wrong
If everyone is calling a swan, a swan. And you call it a dog. Yet it has wings. Who is right?

Bro I killed like 5 phones with water damage then I learned Abt the rice thing and I would've killed like 3 phones and a switch with water damage but I saved them 4 thing with the rice &&^&^$^ dumbass the water need to have not damaged in order to save it

I have an iPhone….. the battery doesn’t just come out.
Jay Williams - Antwort
Nice idea but iPhone doesn’t let you open it. The only thing you can open is the little slot on the SIM card and that’s it. You can’t open the back to access the battery.

Will non flammable electronics that leaves no residue be the better choice? “Scrubbing” might lead to physical damage.
