Divide By Zero said:I use a good quality ziplock bag inside the ultrasonic cleaner.
Ziplock brand does not use BPA in their plastics.

It blocks less of the ultrasonic waves than glass/paper/cardboard.
It also makes cleaning up a snap!
What a great and simple idea ! And the ultrasound don't cause the plastic to leach ? I already know at these temperatures we're fine because we can't apply heat over 32 C...
