Ultrasonic cleaning
I saw some vids demonstrating washing clothes with ultrasound. It can remove dirty stains from food, but not the printed dyes, why?

I would think that it depends on the type of dye, type of fabric, and type of stain, as well as the ultrasonic strength. For example, if I place a
piece of cotton fabric in my ultrasonic at 40 kHz overnight, it almost completely destroys the fabric. It dissolves Al foil in seconds. So I am sure
that ultrasonic could remove printed dyes as well, but a clothes washer would be adjusted to not do so.
