Hello all,

We all have read about this issue for a while now and I will not touch the basics on it, just a specific.

I heard about this ultrasonic method to clean and restore circuit boards from corrosion and mineral deposits, have any of you guys heard anything about it?

If so, what kind of chemical do you use to clean? The brookstone ultrasonic cleaner (Ultrasonic Jewelry and Eyeglass Cleaner) suggests tap water but we all know this is not a good option, some have recommended thinner and others a combination of thinner and isopropyl alcohol.

Can anyone advise what the best chemical is to clean the iphones motherboard? and how effective is this ultrasonic method?

Thanks!

Did you ever get a response/figure this one out?

Well, if you use it i would use destilled water(maybe some detergent if it was damaged by coke or anything similar) or isopropanol(normal waterdamage).

But the problem with the ultrasonic method is the physical stress for all the parts and solder points.
So i wouldn't recommend this method

Usually i would use:
1)for anything except water some destilled water with a bit detergent and clean it up with a brush
2)and than put it in a bath with isopropanol >97%, again clean it up with a brush or toothbrush or both (carefull) u should leave it in there for a few hours(or even days) and brush it a few times
3)put it into some clean iso, brush it again take it out dry it

for normal water just start @point 2 but 1 wouldn't damage the board anyway

the thing is that carbon compounds(for example iso) wont remove beer, coke, ...


the point is that u want to fix for the next month/years and not just for a few weeks
