[Zbrush] Slice Brushes and excess slices: How to clear?

Mawedking

Its my first time using panel loops and I'm using slice brushes to form my polygroups. I've ended up with many excess slices that are distorting geometry in some areas. The only way I know to clear the slice marks is to dynamesh, which also ruins the clean edges on the new polygroups. 

Is there something I'm missing to clear the slice marks? Or any other suggestions to avoid excess slice marks altogether?
Thanks in advance for the help!
