Within a month of using the new vitamix container it started to get cloudy around the bottom and with each passing week it shows more and more cloudiness on the sides, and I've only been using it for a total of 6 weeks. I have been cleaning it per instructions after each use, but it doesn't help. This is the reason I bought a replacement, my last container got so bad I couldn't read the measurements. I purchased my vitamix blender over 10 years ago, and many friends have seen me use it and loved the smoothness of the smoothies I made for them and then went on to purchase one for themselves. But I just cannot continue to recommend the blender anymore, because the container is too much of an issue. It starts to look grubby on the countertop. And they're not cheap to replace.

I have an original C series or TNC machine. I was always envious of the new low stature containers and when I noticed there was a 1.4l container available for my C series, I bought it. I have to say, it is nowhere near the quality of my original container. The clear plastic handle is quite thin and the lid is made from a hard plastic. This renders it completely inflexible and hard to fit.

We have had our Vitamix for 2 years and we love it. The only problem is the interior or the plastic container scratches and gets cloudy making it visibly unattractive. Only dish detergent is used to clean it. We only use vegetables in the blender and avoid seeds and acidic substances such as lemons. I'm not sure why this interior deterioration occurs. If you could make a glass or Pyrex container that would be wonderful. But the plastic just doesn't compare with the quality of the machine.
