Yes, add rice and boil until cooked.

It is as safe as it is pointless.

BTW, if you have not unplugged the battery until now, your macbook is a toast by now if water actually got inside. Turning it off does not necessarily help a lot, standby circuits are still under voltage.

MAC-AIR-oni (Cheese) on toast, with some RICE and sliced APPLE. Should taste really nice, with a nice hot cup of TEA (which you have already added  :-DD).

Hopefully remove all power sources (all batteries), thoroughly clean with safe substances, and allow plenty of time to be absolutely dry before ever powering up again. Else it may destroy itself with electrolysis.

Well he should take the laptop apart (or take it to somewhere who can) and disconnect the battery first, then watch the video.

If rice works then why not cat litter.

There is something in black tea that corrodes the hell  out of pcb traces and keyboard contact pads. I don't know if it is the tannins or what. Disassemble and flush with water right away. I have wrecked 2 keyboards that way. It surprised me the first time as I thought tea was fairly benign.

I've heard rice works well but never had the need to use it, one thing I will say though is that last summer I boiled up some rice in preparation for a stir fry which we have often, anyway on this particular occasion for some reason I didn't give the used rice pot a wipe out and rinse which I would normally do prior to doing the dishes and left it on the bench over night, the following morning I came out into the kitchen to make the coffee and found two black house spiders, one white tail spider and some other unidentified creature all having breakfast in the rice pot. I could only assume from that particular experience that they are attracted to the smell of cooked rice so we have been pedantic ever since in not leaving invitations like that around.

Spiders suck.    :scared: :phew: :--

I keep a couple of kilos of silica gel around for just such occasions. Rice is a bit of an old wives tail that harks back to putting rice in the salt shaker to stop it caking. That was a mechanical process, but people believed the rice absorbed water in preference to the salt.

I also have a big pot with a silicone seal I use with calcium chloride. That will suck the moisture out of silica gel, but it's a one time affair. Cheap enough though.

Right tool for the right job.

Rice is a total waste of time and just contaminates the equipment further.

To be aware, some computers have non removable main batteries now :(

Also many laptop designs use a separate battery to provide power to the RTC etc. If there is a battery of any sort connected to the PCB, electrolytic action will normall start eroding pins of components that are powered.

A laptop that has had a 'bath' should be disassembled and at least inspected and cleaned by a competent person knowledgeable in fluid damage repairs on computers. Speed is of the essence. Do not wait a few days to get it disassembled and cleaned.

As you well know, generally around here it's the chainsaw that is best suited when dealing with these big black hairy monsters. Anyway, as she who regularly takes them out back always says objects may appear larger whilst idiots are wearing empty coke bottles.   ::) :P

She......that is scared of such things thankfully can't use a chainsaw (I've a few) but she can use a shotgun....one of the reasons why I keep them locked away.  :scared:

I heard that it is suppose to be boiled rice that has been baked dry.
Apparently used to keep film stock viable in the jungle during the Vietnam war.

No. You wanna rinse away all the tea before it has a chance to cause corrosion — the rice method simply delays this crucial step. (See the first video.)

Louis Rossmann in agreement with the first video also concluded that the rice drying method does more harm than good by not immediately and properly addressing the issue in addition to possibly leaving harmful residue, definitely some good advice to be had here.

Yep, I'll be concurring with Louis's point of view.  I've received many machines and phones that have rice in them after several days of corroding away (phones especially!).  The whole rice myth is resulting in a lot more damaged equipment than there needs to be.

For me though, the greater peeve is when people choose not to honestly tell me that it's been dropped in a [dirty] toilet, good reason to suit up and have a big container of IPA on the ready - damned biohaz :(

I've watched this video before, and I didn't understand it then. I'm glad have the opportunity to question it now. Louis acts like people believe that rice is somehow going to magically heal corrosion damage on the phone. I don't that anyone believes that beyond a few real dummies.

I thought that the idea of surrounding the device with rice and putting it in a dry place is that the rice helps absorb the water/humidity from the phone, as rice does function as a desiccant to some extent. Therefore, the point of the rice is an attempt to dry the device as quickly as possible if water gets inside the phone or perhaps stuck behind the display. The reasoning is that the faster the water is removed from the device, the less corrosion occurs.

I understand that Louis and others are frustrated from dealing with stupid customers all the time, but it seems insulting their intelligence to act as if they believe sticking rice on corrosion is going to heal a phone. No one thinks that or ever thought that. The rice reasoning was an attempt to remove water from the phone as fast as possible and prevent corrosion damage. I'm not saying that there aren't better ways to do that, though because there are. However, the desire to remove the liquid from the device is complete rational and is "denial" or the belief in magic. The sarcasm that always accompanies this topic seems unnecessary and a bit demeaning.

What do you guys think? Am I missing something here?

That is the kernel of truth in this urban legend.

The problem is that rice is not a good desiccant. Not at all.

It is like saying: "jet propulsion works, so if I eat a can of beans, I should be able to fart my way to the moon". The principle is correct, but magnitudes of effectiveness are not even close.

Even real silicagel is not going to be super helpful in this case.

   It's a bit of an inside joke as it were, with a lot of satire / sarcasm heaped on for effect.   No, Louis doesn't believe that people believe that it magically heals things; it's just over-the-top drama for comic relief of others in the industry to watch.   I'm sure if you were to ask seriously, he'd agree that most people simply believe that rice will dry out their equipment to the point where it works again.

   Essentially that it's humour/blow-off borne of frustration that runs with the industry; likewise you'll find the same sort of thing among mechanics, doctors, architects.

I guess the joke went over my head. Thanks for setting me straight.

I keep a couple of these rechargable silica gel drying blocks handy, just for pulling out the last bits of moisture from items by sealing the phone/board in with the silica gel  in a small container for 24hrs or so. 

No good if it's sopping wet, but good for after you've already washed/dried it off as much as you can and just want to get those last bits.

Nutting says lovin like something from the oven.  Just take the battery out and stick it in the oven, should you have something other than a microwave, on a low temperature setting like proof (120F).  My wife has hearing aids and they supplied her with something like a coffee cup warmer to put them on.
