Plastic cases that go sticky
Gyro:
I think I mentioned it once before in another sticky goo thread, but I have a Logitech Harmony remote that suffered rubber breakdown on the rear surface. I completely removed the coating with meths to reveal... another, solvent resistant, Logitech logo. Now that's thinking ahead!

It's almost as if they knew/expected their product to degrade in this way.
It reminds me of a pair of running shorts I bought. The laundry tag literally says "Designed to fade".

Right. I'll be in that corner there stuffing crayons in my nose and eating wood glue. :-[

I've got a USB stick with this very problem. I've put it in the EPROM eraser for 1 hour and we'll see what happens.

The caution label says "contains Ethanol UN1170" but no mention of Methanol or complete ingredients list. Yes, purple in colour with distinctive smell. Sold for spirit lamps / stoves, hard surface, and glass cleaning, de-greasing etc.

It depends on the country, "methylated spirits" here is almost pure ethanol with a tiny amount of denatonium benzoate added to make it unpalatable. There's zero methanol content, which would make it poisonous.
