How to destroy spline mesh components?

How do you destroy spline mesh components in runtime (not construction script)?

I can create the spline and it’s mesh components, and have tried to piece together a solution based on other’s examples, but cannot figure out how to get rid of the things when needed. Drawing a new spline leaves previous iterations behind, connecting the mesh components perpetually.

Destroy components isn’t doing anything for me, maybe I’m referencing it wrong.

Can anyone help point me in the right direction?
