Est-ce qu'on peut vraiment absorber l'humidité avec du riz dans un appareil électronique ?
Réparer une tablette, un ordinateur ou un téléphone qui a pris l'eau, c'est un peu comme de la pâte à crêpes sur la table de la cuisine : le jour même, elle est relativement facile à nettoyer. La pâte à crêpes séchée le lendemain matin, c'est une autre histoire. Il en va de même pour les dommages causés par l'eau ou les liquides.
Lorsque nous mettons un téléphone dans du riz, c'est la même chose que de ne rien faire. On a juste l'impression de faire quelque chose. La corrosion est instantanée lorsqu'un téléphone entre en contact avec de l'eau. Parfois, la corrosion atteint des composants importants, parfois non. Si nous résistons à allumer le téléphone jusqu'à ce qu'il sèche sur la table de la cuisine, dans du riz ou n'importe où ailleurs, nous avons parfois de la chance. Si c'est dans du riz, nous pensons que le riz a sauvé le téléphone. Mais ce n'est pas vrai ! Même si le téléphone semble fonctionner, il aura des soudures oxydées et fragilisées. La corrosion continuera à se propager à l'intérieur du téléphone. Bref, ce n'est qu'un coup de chance temporaire.
Le vrai secret des dégâts des eaux ? Il ne faut pas essayer de faire sécher !
Comment faire sécher un téléphone sans riz
En fait, il faut d'abord déplacer l'eau – ou plus précisément, tous les éléments oxydants qui se trouvent dans l'eau. Pour ce faire, vous pouvez utiliser de l'alcool isopropylique à plus de 90 % et une brosse à dents. Ouvrez votre appareil dès que possible, retirez la batterie et commencez à frotter. Plongez la carte mère dans l'alcool et frottez. Ensuite seulement, séchez-la et voyez où vous en êtes. En déplaçant le liquide avant qu'il sèche, vous nettoyez la pâte à crêpes le jour même. C'est la meilleure stratégie à adopter en cas de téléphone qui a pris l'eau.
Bien sûr, il est tentant de mettre le téléphone dans du riz – on ne sait jamais, cela pourrait marcher. On ignore les explications ci-dessus et on espère que tout ira pour le mieux.
Vous aurez du mal à trouver une seule personne compétente en réparation électronique qui ne lève pas les yeux au ciel lorsqu'elle entend parler de "portable + eau + riz". Nous vient alors à l'esprit le triste résultat des téléphones et appareils qu'on a soigneusement placés dans un bol de riz en croisant les doigts.
À toutes les réparatrices professionnelles et réparateurs professionnels : nous vous invitons à partager des photos de l'intérieur d'un téléphone ou d'un appareil qui a fait trempette dans du riz. Une image vaut mille mots. Peut-être que nous finirons par chasser la légende urbaine du riz sauveur une bonne fois pour toutes !

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)

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

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 - Réponse
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

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.
