Computer / Electrical Cables In The Dishwasher

I have a number of computer cables worth several hundred dollars in total which have come into my possession, that were stored in such a way that they may have been contaminated (nothing a good washing wouldnt fix). I would prefer not throwing them out. Most of us have probably heard about washing a keyboard in the dishwasher, and now I am wondering if the same logic can be applied to dirty cables. My assumption is that because the older PS2 keyboards used in these dishwashing experiments have their own copper cables attached, what could be the difference? I am wondering if any of these cable types have different material or fastenings that will not hold up in a dishwasher, under heat, or when wet.

The assortment of cables include:

HDMI cables
DVI cables
VGA (DE-15) cables
Other DSUB types
Cat 5e/6 etheet cables
SATA cables
USB cables (Micro, Mini, A to B printer types)
Speaker wire
S/PDIF cables
RCA cables
3.5 mm Stereo cable
Auxillary cables (to headphones jack, maybe same as 3.5 mm)
Computer Power Cables (IEC60320 C13 standard)
Any C-Type standard cables for that matter
DB-25 Parallel Printer cables (I know, throw it out)
D-Sub

Follow up questions:

1. If there is conce about the temperature of the dishwasher (although I cannot imagine it hurting the cables and not a keyboard), can they be washed by hand?

2. If there is any water left in the cables after several weeks of drying out, could they damage the electronics they are plugged into? Or will they simply not function?
