I’m on my second Ultrasonic cleaner. The first one I got for like $45 was made of plastic and broke after just two months. I got an all metal one last week and I’m pretty happy with it so far. It has a heater which makes the cleaning happen a bit faster.

I keep the tank full of just regular water. I put my nails and baskets in a ziplock with a little purple/orange degreaser and the put the sealed ziplock into the tank. Putting the cleaner directly in the tank works but it gets gross fast. Using the ziplock lets me use a smaller amount of cleaner too.
