Deleting geomerty

Hi
I like to know how to delet geomerty i see in the dynamo grafics window cause it get very cloggy.
As you see I have imported an item and it pops at a location with a rotation. But i like to move and rotat it to the correct place. How ever I get 3 geomerty instead of 1. Is there a delet in view fuction to run on the others?
