I then sit it vertical so the water slides/dries off the side. This usually gets rid of all the dust for me.
Sometimes the water doesn't completely slide off and it ends up worse than when I started, so I just do it again.

Hi,
I think water even distilled water is not a good idea. I use 99.999% pure isopropyl alcohol with 10% ether. This dries away wothout leaving any trace on the chip.
