I drink cold brew coffee. Normally I leave the coffee to brew for 24 hours. I’m considering of buying ultrasonic cleaner for brewing my coffee. I wonder if that’s going to work.

Watching YouTube videos on smoking / flavouring liquor using these cleaners gave me the idea.

N.B. not cold brewed coffee

That doesn’t sound food grade. Is there a method to line the cleaner basin with something food grade?

They put the drink in a mason jar https://youtu.be/YlQT4ptwLKs?t=15h34m

And that jar goes in the cleaner

This also works for cleaning items in solvents and flammable liquid. Put a secondary reservoir inside the ultrasonic tank.
