No, I did not but I could have. I had to disassemble it after the bath to make the drying easier and faster. The thing is that disassembling the 35s is troublesome and almost always leaves dents etc. The calculator has a big opening on its back that is covered by the battery door.
Pure alcohol (C3+) is preferred over regular alcohol (C2+water).
If you are willing to give this a go, use a white bowl and take pictures of the alcohol, if you can.

It was not just the color, but nearly a whole set of capacitors. I have a picture of that if you're interested. My point is, if HP is still manufacturing the 35s after almost 10 years, why not work on a 35sII? Since the target is exams, anything beyond the 35s/TI36xPro capabilities won't be allowed. Maybe faster, smaller and with STO unshifted.
