Isopropyl Alcohol and the water damage square

Ok i was cleaning my battery contacts and my usb pins with 91% isopropyl alcohol and got some on the white square and it turned kind of pink (small faint pink spots)...like as if water damage was done...any suggestions? am i screwed on warranties?

Buy some new water detecting stickers off ebay and cut to size. If not Satan I mean ATT will black list you for warrantys when they ask you what color it is, they dont care why its pink, its broke and your fault even if it never had water damage, no joy!
Spend the 8 dollars plus .42 cent shipping to ease your issues Just my personal experiences.

Well, it's definitely a lot better than having water on it. Alcohol boils at a lower temperature, meaning it will dry up a lot faster. Keep the battery out for a few days and put the device in rice to drain everything out. Hope it goes back to normal.

do you have a link for those stickers..i cant find them anywhere

I'd bet it is not reacting to the alcohol at all, but to the water in the alcohol. Remember even 100% alcohol isn't (or is only fleetingly). The instant you open the container and expose it to air it starts absorbing water.

[Q] HTC HD7 water death!!!!

Hi guys, I recently fell into the sea by accident and my phone was in my pocket and it got wet. I did not know what to do and i thus took out everything and wiped it dry and then plugged it into a power source. No response. After a few tries, it started vibrating madly and the light on top of the device started flickering. The phone started heating up like mad until finally i switched off the power supply. Now it is not giving any response. Please Help!!!

you fried the board.

In future if you ever get a phone/anything electronic wet, immediately remove the power source (battery) and leave it to dry in a well ventilated place for a long time (or a bag of dry rice, which can draw the water out). And when you think it's dry, leave it a bit longer still!
Don't be curious and try turning it on "to see what the damage is", as you will invariably cause more damage.
Unless it's tap water that's spilled on it (or it's been submerged in) you will likely want to wash it out before drying it - pure, deionised water is good for this. This might seem mental, but it's not - pure water is generally harmless to electronics unless there's current running through them. The residue from dried seawater or coffee will cause short circuits and damage the thing, so best to wash it off.

Seawater? Ouch. If anything salt will kill the motherboard faster than the water. But yes, you made a mistake by plugging it into a power outlet after drying it out. Next time (which hopefully does not occur), pull out the battery, dry it out, and stick it in a bag of rice or silica gel packets. Waiting a few days before touching it would also be a good idea. You may be able to try this now and to rid of the salt, soaking the phone in 100% rubbing alcohol (only 100%!) may clean out the internals. Good luck!
By the way, I haven't tried out the alcohol method but it was suggested by other forum members. The worst case scenario with the alcohol is that some of it seeps into your screen and won't evaporate, so try out the rice first.

It's a common misconception that water conducts electricity. In fact, it's salt water that conducts electricity. The problem is our skin has minute amounts of salt on it. It has been tested already making a completely water submerged PC as an advanced cooling method such as using cooking oil. The plus side is for circulating, water isn't as thick & flows faster plus it don't "go bad". The downside is you have to be very careful not to let salt get into the water & how hard it is to find "pure water".
P.S. DO NOT TRY IT YOURSELF. Even Mineral Oil can be dangerous to PC parts if you don't know what you are doing, plus Oil dissolves rubber & plastic parts over time.

Are you joking? Water conducts electricity. Distilled water (saltless) conducts electricity. Mineral Oil != water! And it does not conduct electricity (the pc cooling projects).

You may be right that distilled/Pure water conducts electricity, for that matter everything conducts electricity if enough voltage is applied. Even air as proof by Lightning. Computers run on 12/5 Volts though (except the Power Supply that turns 220/110 Volts into 12/5 Volts). This is not enough voltage (the 12/5 Volts) to pass through Pure Water. The point is people have tried it & it works. Would I recommend it to someone, NO. As I said, any contaminants will increase water's ability to conduct electricity. There's parts in the PC that can give off salt & other contaminants into the water. Our devices work on less than 5 Volts. If you take the battery out immediately & let dry out completely. You can save the device. I've done it myself & helped others save their doing this. The best choice for a advanced cooling system is this 3M liquid, but it's extremely expensive.

Excuse me, Distilled water has no free ions which are found in normal tap water (minerals, K, Na, Mg, F) that's why it won't conduct electricity, but as " drkfngthdragnlrd " said at extreme voltages not currents, it totally can and that's what's exhibited in stun guns for example where air itself connects..

Help: Note 9 display blinks after being hit by rain

Hello Fellow note 9 users,
Please any advice will be appreciated, i got drenched by rain and my note 9 display starts blinking and some parts of the screen wont even respond. I couldnt power it off because of the pin which can be entered due to the scrren defect. so i kept it in rice for a day and also used hair drying, to my suprise, the affected part works so i have been able to switch it off because the screen still blinks and not stable.
What can i do again because the price of the screen it out of this world. any advise please

Power it down immediately!!!
It must be opened and dried ASAP!
Disconnect the battery first.
Flush with copious amounts of anhydrous isopropyl alcohol. Allow the alcohol to absorb the moisture then displaced as much of the alcohol as possible using a flinging motion or better, low pressure compressed dry air.
The room humidity should low so the hygroscopic isopropyl doesn't grab moisture from the air. It is flammable!!!
Allow to dry completely before plugging battery back in.
A day or two in a warm dry room with a fan on it should do the trick.
Time is of the essence to save this device!!!

thank you, i have opened it and blowed it with low pressure air. although its still opened. i will need to get isopropyl alcohol then.
Thanks for your help. i just hope it works

Disconnect the battery. Energized circuits corrode.
If there's no apparent moisture, leave it air dry in a warm room for a few days with a fan on it.
If any moisture gets into the microconnectors for the ribbon cables it can behave like that.
It can be difficult to detect... one small drop is all it takes.

Alright thanks. will leave it dry

Once my Buds case fell straight into a full cup of coffee, cream and sugar. Fortunately the Buds weren't in it.
After a brief deep cup savage mission I tore it straight apart. The battery is spot welded in so in it it stayed. Fortunately I has RO water to flush out the sugar with and I always keep a bottle of anhydrous isopropyl on hand. Chased the RO water with alcohol and left it to dry.
A day later I checked it out. A-OK, a little bit of sketchy performance at first but that soon subsided.
2 years later it's still is working.
Fast action can save devices even from coffee
If it's salt water though... it's already dead

I have dried the phone well, but can I use methylated spirit to wash the internals, It contains alcohol also. Or what do you think

No! 99% Isopropyl alcohol only. Drug stores have it although it may be 96%, not perfect but acceptable. Don't use 70%
No telling what additives are in denatured ethanol alcohol.
Ethanol it's self may react differently to the plastics than isopropyl.
You want to limit exposure time as well; permeate everything and get it off as quickly as possible.
NEVER use any kind of solvent including isopropyl on or near a LCD display, it will kill it.

Hello, thanks for the help so far, I got isopropyl 88%. Is that fine? Can I use it on the motherboard?
Thanks for the help

That's 12% water... not good. The purpose of using anhydrous isopropyl is to absorb the moisture thereby displacing it.
That extra 12% is a lot of water you don't need.
You're better off leaving it open with a fan on it in a warm dry room.

No. Anhydrous isopropyl is 99% pure isopropyl alcohol, the rest in water.
You want it's chemical and physical properties.
I have no idea how that combination would perform. You already have one rogue experiment running, don't add more variables to the mix!
At this point just leave it open and allow it to dry completely.

Hello, Thanks for the help so far. After leaving it to dry for few days now. I finally put it up yesterday and it came up. the screen and all works but i noticed the screen is a bit faint, i mean not sharp and when i lock the phone, before the AOD shows, i notice like a white flash towards the bottom of the screen.
please what can i do again,

I noticed something again, if i increased the brightness totally, i wont see that blurry aspect again. everything just looks good but very bright, but once i decrease the brightness to the normal level, i start seeing that blur and thick lines underground

Still has moisture present or contacts got corroded. Pull the battery!
If you can pull off the ribbon connectors the display, carefully do so.
Disassemble as much as possible then flush it well with anhydrous isopropyl. Remove as much of the alcohol as possible, allow to completely again. It will need extended drying time if not fully disassembled. Keep the drying area warm (heat drives out moisture) with a fan on the phone. You can make a warm box for it if you leave in the tropics. Any heated semi sealed enclosure with a couple cubic feet or more of space will do but keep it the temp below 140F.
Observe ESD protocols as best you can as static discharge can easily damage out of circuit subassemblies.
Make sure, at least, the room humidity is 50% or higher when handling. Use a bare wood table or piece of wood to work on if you have no ESD mat. Discharge yourself to an earth ground frequently if no wrist strap but do not touch earth ground when handling components.
If you can feel, see or hear static discharge, it's already way more than enough to cause damage.
Move to a drying area when done, but reassemble using ESD protocols.

thank you for all the help so far, so i should discharge myself continuously, open up the phone again and dry out the board and wash with isopropyl and dry out again, right.
thank you

After doing all you mentioned, heating the board countless times with even hair drying, powering it back on, still gave me the same result. I dont even know what to do. i might do a little video of the screen so you see what i am saying.

The chances of repairing this device are not good. The battery may have been connected too long after exposure. Every time you connect the battery before it's dry, the more damage is done.
Using a hair dryer is not recommended.
It needs to be torn completely down at this point and all ribbon cable connector pins inspected. The mobo may have corrosion damage. If it's under a BGA* it's not practical or easy to repair. Corrosion damage is insidious and progressive once started.
If it's just water with no formed corrosion under a BGA, in a connector socket etc, anhydrous isopropyl alcohol can be used to chase it out.
Pull all ribbon connectors first. You'll need full access to the mobo and display.
Flush well and repeatedly. Use low pressure dry air to blow off as much of the alcohol is possible.
Pay special attention the BGA ICs, blow the alcohol out from underneath if possible.
Out of circuit subassemblies are susceptible to ESD damage ie static discharge. ESD procedures should be used when disassembling and handling the subassemblies. Leave dry in a warm dry area with a fan on the parts for at a few days. All areas including under the BGA's must be completely dry before powering it up again.

Question Emergency help need to recover my phone

Hi guys
My phone was dropped in the water. I gave time to it and make it dry by hairdryer and put it in rice to absorb its humidity. Then I opened the back panel and made it drier. INow when I press the power button nothing happened. Just when I connect it to the charger, the charging logo and then start screen appear and shows 1 percent charge, is charging and then disappear. it repeats without starting normally. What is your remarks folks?

Something is shorted, just send it to someone to fix it and tell them it's water damage.

Disconnect the battery immediately.
Rice does nothing.
Get some anhydrous (99%) isopropyl alcohol* and liberally flush the entire phone with it to absorb the moisture.
Use low pressure compressed dry oil free air to blow out as much of the alcohol as possible.
Do it in a dry room and it is flammable.
After you get it as dry as possible allow to dry in a warm, dry room with a fan on it.
Let it rest for at least several days.
Reconnect the battery and see what you got.
* never use isopropyl alcohol or any solvent around an LCD display, it will poison it. Should be safe for AMOLED displays. Try to prevent it from getting in between the display and the glass if that can happen.
Use your best judgement.
The more you can safely disassemble it before flushing it out the better. Be aware that individual assemblies like the display and mobo are sensitive to ESD damage when out of circuit.
In a dry room handling them is risky if you disconnect the ribbon cables. Unfortunately this is exactly where water tends to get trapped.
If you disassemble to subassemblies level raise humidity in the room to 50% and use a plain wood surface, or earth grounded ESD mat to work on. A ESD wrist strap is highly recommended.
It may be best not to remove the ribbon connectors other than the battery, flush it well, and allow more drying time.
Either way you want to dry the assembly in a warm dry remove to remove all residual moisture; it must be completely dry before powering up again.
If any corrosion formed as a result of the water exposure especially with the battery connected it will not be salvageable.

Lol, that sounds more complicated than having a heart transplant.

Well once you get a device wet, speed and appropriate actions make the difference between a paper wieght and a working device.
At least I gave known good advice*. Manufacturers won't even attempt to salvage them because experience has shown it's not worth it.
*dropped my Buds case in a full coffee cup (cream/sugar). Immediately pulled it out and apart. Flushed first with RO water to dissolve any sugar then flushed with anhydrous isopropyl.
A day later it was charging again. 2 years later it still works. And that was with the battery in it.
The coffee was still drinkable too

Question How do you clean USB port?

Hi, I use my phone under water and in dust, and I might have to clean USB port since charger sometimes do weird disconnected-reconnected feedback.
How do you clean it? Alcool, WD40?
Thanks!

Why not use a case that closes off the USB port and switch to a wireless charger? I wouldn't use wd40 as it will damage the seal over time

Use dry air to blow out dust/dirt.

Definitely no WD40. Can mess up the phone if it gets through the seals.
Compressed air works great for port cleaning. It will get rid of most loose particles.
For stubborn traoped lint etc, fine micro-tweezers do the job well but need to avoid damaging the USB shelf in the centre.

I use isopropyl alcohol and cotton bud

Don't use it underwater unless you really want to destroy the phone. You need a diving case to safely use it under water.
Using compressed air can easily force the water into the phone. Only very low pressure like a blower bulb should ever be used.
Anhydrous isopropyl alcohol is a good drying agent, use in a warm, dry room and it's flammable.

I wash my phones under the tap with some soap. Keeps speakers mics and ports clean. Use a toothbrush and some alcohol of this doesnt work.

I live in a dusty environment, in the desert. The most I've had to do with my N10+ was purged moisture in the C port once with anhydrous isopropyl alcohol. It doesn't collect dust in spite of no cover. Maybe use a blower bulb occasionally.
Other ports, less is better. Qtip and blower bulb every 6 months. The recessed holes in the Bolt case also help keep the junk out surprisingly well.
Once you replace the battery I doubt you will trust deliberately exposing this expensive flagship phone to water. It's one seal, one layer of protection and no guarentee it's 100% sealing the phone. It not an rounded edge seal and less reliable; double sided adhesive. This type of sealing system should not be trusted to be watertight especially under pressure.

I'm talking about latest generation Samsung phones. I have 2 N10+'s. Some of the ones with removable batteries had better seals.
Salt water is sure death to electronics.
Do what you want but it's not like you didn't know better... at least put the phone in a zip lock bag.
These are not dive rated phones... that includes swimming.
Did you notice that Samsung doesn't do those cute underwater camera shot ads anymore? That's because of all the water damaged phones they caused. Carriers ate a lot of them.
