Ice Machine

I have purchased an ice shaving machine to crush solid ice into small shavings. It is mostly made of plastic. However, the part that is doing the actual shaving is made of metal. Does the ice shaving machine need to be immersed?

Thank you.

If you can disconnect the metal part, or the piece containing the metal part, and immerse it, you should.

If there is no way to remove it without breaking the machine, and the machine will break if you immerse the entire machine, you do not need to immerse it.
All the best
