I got a Keureg for Christmas and it was like that for a bit, then I washed it with cool soapy water and rinsed it well and now it's amazing. It's always better not to use hot water on plastics bacause hot will often make the soap get locked the plastic. I tried that on my Gevalia and I tried vinager and I ran a ton of empty water through it but it always smelled and tasted like plastic. I guess they just use cheap plastic.
