Granted, I'm a germophobe. Doubly so after my transplant.
VitaMix
There are two hard to reach cavities.
The outer ring of the top plug fills with debris. https://www.webstaurantstore.com/vitamix-062984-lid-plug/HP7... This one really pisses me off. It'd be so easy to redesign the plug to eliminate the cavity.
The second is the underside of the pitcher, between the side wall and the center spindle. This one is only annoying. Can't find a pic, but this is the pitcher. https://thingsaroundthehouse.com/vitamix-7500-vs-5200/
I use looped pipe cleaners to scrub these cavities clean.
I could fully disassemble my former KitchenAide's pitcher to clean every component. Alas, the Vitamix does better with all the big leafy greens I now consume.
InstaPot
I like the cord unplugs from the appliance. This should be the norm.
Where do I put the cord? Inside the pot? Great, now I have to clean the cord too. Or rinse the pot before using it again. Sometimes I kinda fold the cord and stuff it thru the top handle.
