Bob- I know I seem to have gotten under your skin for some reason, so apologies on my part if I have. Not intended. i am just talking, as you are.
I would caution though on this advice- if I have no notch on my blade, and there is nothing to be removed, obviously either we have different blade setups or something is awry.
And I don't have any buildup, nor do I have a bad smell on my blade, despite being used a minimum of 5 times per week since May.....
Here is what I think, the blade assembly that has the notch, has a removable gasket and this is the one they are currently selling with the Nutribullet. That is why when I posted my first post on this topic, I made note of the "small notch" that allows the gasket to be easily popped out. If you don't see that notch, I suspect that there is a possibility that your gasket is not removable. I am assuming that the notch was included on the newer blades, so that the customer could remove and clean the gasket. This is not spelled out in the instructions, and I think that is a something that should be included in the owners manual. Allowing that material to accumulate on the gasket, is not the healthiest thing in the world, in my opinion.
What made me aware of this issue, is someone else posting on the other thread that I put a link to, that they had a blade assembly that started to get a bad odor. They found that it was coming from under the gasket, and when they called customer service, they sent the person a new blade assembly. ( You can read the other thread if you want). It seems like Nutribullet doesn't want to weigh in on this issue, which is bothersome to me, because this affects people's health. I just ordered my daughter a Nutribullet for her birthday, and I am going to show her, when she gets it, how to remove and clean this gasket..
