My beloved AllClad does have a silicone seal around the metal disk that acts like a low roof, if you will, on the inside of the bell of the blender. I've seen stories of folks having trouble with that seal failing. Fortunately my DH is a pretty good fixer-of-things, and he feels confident that he can repair this if it does fail.Be careful with the fancy stick blenders because they often have a flexible gasket or seal around the impeller shaft. Flexible seals aren't usually used on cheaper stick blenders. These flexible seals are rated for exposure to food, not concentrated alkali, so they will eventually fail if you use them in soap batter. Better to use a cheapo stick blender that only has a less expensive metal-to-metal seal around the shaft.
I learned this the hard way -- dear husband got me a fancy Bamix once-upon-a-time. I use it only for food nowadays.
I'm thankful for that but still holding my breath. This is by far the best SB I've ever used when it comes to lack of bubbles, low speed, and ability to blend small amounts at a time. If it fails, for me it will be a tragic love story: me left standing as the bereft princess after the prince dies while trying to save her.
In the meantime, I use it sparingly and dunk it immediately in a waiting container of hot soapy water when blending is done. It's also the first thing that gets washed after the soap is in the mold.
