Hi.
Mixers have their bowls and blades toiveled.
I’ve never heard of anyone toiveling the machine itself.
Years ago we bought a George Foreman grill that had cooking surfaces that couldn’t be detached.
I asked a shaila about what to do, since toiveling would likely ruin it, and was told that I didn’t have to toivel it.
As this site’s disclaimer says, “One must ALWAYS ask a Rov a Shaila, and NEVER Pasken from the forum!”
