waider | self-defeating coffee mug

I bought a cheapy heated coffee mug - it plugs into a cigarette lighter socket and keeps your coffee warm - but mostly for use as a giant coffee mug rather than an in-car pick-me-up, since I don't have a coffee cup holder in the car. It holds >1.5 times the standard office mug, which is nice. However, I have noticed that you can't get rid of the smell of cheap coffee no matter how much you wash the thing, so I can't drink anything else out of it now - it all tastes like cheap office coffee. Bah.
