What types of cleaning solution should I avoid using

Agitating the ultrasonic cleaning bath is okay. However, it depends on the kind of agitation done to the bath. If the agitation is extreme, the effect of the cleaning process is diminished. If the agitation is gentle, the cleaning becomes better. Contaminants are removed by the slow and gentle movement of the cleaning bath. https://www.youtube.com/watch?v=AgSNrKpmS1g
