I'm not adding anything useful here, but I just gotta chime in and agree with all the others here.  24 hours is not enough time to get computers dry.  A week, as the others have said, is what you should have waited.  Sounds like you might have damaged the Amiga that you turned on after 24 hours, as there was probably moisture still underneath the components, and in all the nooks and crannies of the circuit board (not just the visible places).

What conclusion are we trying to draw here-- that even if you bathe the Amiga, it will still work as long as you dry it out for a week+ ?

I had a floppy drive that was really dirty and most disks failed on it.  I bathed it in water and tried after letting it dry for a month and it still does not work.  It was better when it was dirty.  Now it reads ZERO disks.  Seems like I killed something just by the bathing process.


I think it's pretty well known that you can use water to clean enclosed, non-moving components like a circuit board. The motherboard and components (mostly plastic) are all fairly inert things.  A bit of washing & drying won't hurt them (as long as they are not powered up at the time).  Some people have even put computer motherboards in the dish-washer (i.e. Amiga boards) and then allowed them to dry entirely, without problems.

However, you put a disk drive with moving, non-sealed components (i.e. the motors) in water. In a disk drive there are coil-wraps in the motors, other parts that can corrode, water absorbent materials (like the piece of felt opposite one of the drive heads & even cardboard components).  There are also lubricated/greased parts that can be harmed by water (the lubrication can be washed away).  Placing a disk-drive in water was a probably a mistake.

I also suspect that your problem was greater than dust contamination.  Probably head-misalignment.

Water cleaning is only intended for non-moving, inert, sealed components like motherboards, ICs, resistors, etc.

You could have removed just the circuit board from the disk drive and washed that, though, without worry.  In fact, I suspect the circuit board from your disk drive works just fine. It's just the mechanics that are faulty.

Now, in the case of a flood, where you have no choice, and even the moving parts are soaked, a weeks worth of drying is your only choice.
